8 Reports of Volkswagen Tiguans Losing Power After EA189 Emissions Fix

Published 03 September 2016
  
  

We have now received eight reports of Volkswagen Tiguan TDIs losing power and rattling between 1,500 - 2,250rpm After the EA189 emissions software remap.

The remapping programme for Tiguans seems to have started in early July. We are not aware of any widespread problem yet with EA189 engines in other vehicles after the remap. And the problem seems to be mainly with post-2010 Tiguan 2.0TDI 140 Bluemotion DSG automatics. 

It is manifested in a lack of torque between 1,500rpm and 2,250rpm leading to a "rattle" and the the transmissions changing down. We think the software remap reduces the fuelling so we have recommended owners to try their engines on higher cetane 'superdiesel' such as Shell V-Power Nitro Plus or BP Ultimate that generally gives more torque at low rpm and might help.

These are the reports as they came in:

12-7-2016: Report that VAG NOx software fix to 2014 Tiguan 2.0TDI 140 DSG has resulted in a significant clatter under load at speeds up to 40mph and engine speeds up to 1600rpm. Suggests that the software fix reduces fuelling and therefore torque at low rpm.

11-8-2016: Another report of a Tiguan TDI, this time a 2012, developing "a horrible rattle in engine when changing up between 2 and 4." VW told owner she needs to pay for a diagnostic test and if it shows that it is due to the fix then they will refund. She had the fix done by a mobile unit from VW direct. She asked the nearest VW dealer how much this diagnostic test would cost and they quoted £100 but also said they had seen several Tiguans with this problem following the fix and that there was updated software that could be applied and if she'd had the emissions fix with them they would suggest doing this first before a diagnostic test. She needs to get onto the original supplying VW dealer and tell him to sort it out FoC or she will sue.

14-8-2016: Third report of knocking from the engine of a Volkswagen Tiguan 2.0TDI after the VAG EA189 emissions software fix, this time on a 2013 Tiguan. It recently went to the VW dealer to have the software update supposed to address the emissions problem. Prior to the update the car was running perfectly well, but after the change it started to rattle very noticeably under light to moderate acceleration along with increased fuel consumption. Subsequently the dealer took it back for investigation (apparently involving info from the VW factory) which took a week. (Owner was provided with a loan car.) This resulted in a further software modification. Owner got car back a week ago. Since then it has started to exhibit the same rattling and fuel consumption symptoms. Having given it what he thinks is a reasonable amount of time and mileage, owner will report the present problem on Monday 15th and see what the dealer proposes to do. (This Tiguan owner wrote again on 3-9-3016: "The latest is that my car has been with the dealer for over a week, during which they were to test drive it and investigate further. The car was returned on Thursday last. The dealer says that they were unable to identify any problem and technically it’s OK. I can confirm that the rattle problem has not gone away, and consumption is significantly worse than prior to the recall. I now intend to speak to VW GB on Monday for their comments and have registered my interest with Slater Gordon (solicitors).)

17-8-2016: Fourth report of emissions modification to a a 31k mile 2012 VW Tiguan 2.0TDI failing and leaving the owner with "a noisy, unresponsive machine completely at odds with the driving experienced prior to modification. The car was returned to the dealer who, in concert with Volkswagen, retained the car for almost 6 weeks. It was returned last week and if anything is worse, possibly dangerous with unreliable throttle response." The dealer visited the owner's home on 16th August, acknowledged the issues but has done nothing. He cannot fix the car to a satisfactory standard and will not buy it back. Owner had the car from new and it is modified for disabled use.

27-8-2016: Fifth report of rattle from engine of WW Tiguan 2.0TDI after the EA189 Emissions Defeat fix. This was a 2014 Tiguan, performing perfectly before the one and a half hour fix, but started to rattle on the owner's drive home from the dealer. The noise gradually got worse. Owner returned it the dealer, dealer mechanic confirmed the fault and described it as "pinking". Dealer then asked owner to bring car back on 30th June 2016 and has had it ever since. VW sent a specialist from HQ who couldn't fix it. Car then transported to VAG HQ at Milton Keynes. Dealer has supplied courtesy cars but owner has not had use of his Tiguan for 2 months. VW Customer Services in Leeds told the owner his was a "unique case". So that's five "unique" cases reported to HJUK.

3-9-2016: Sixth report of problems after 'emissions fix'. 2015 VW Tiguan 'fixed' noticed that the engine sounds noisier and the idling speed seems faster. The mpg is not good anyway. 

3-9-2016: 7th failed emissions defeat software remap reported on a VW Tiguan. This is a Tiguan 2.0L 140bhp Bluemotion DSG. Emissions Software Service Action 23R7 version 9977 was installed on 5th July 2016 by Cheltenham Volkswagen. Recorded mileage was 22,789. Owner was given a certificate of completion which reiterated the statement of VW's June 2016 letter that performance, fuel economy and noise would not be affected. Owner was very unhappy with the loud knocking noise between about 1,500-1,800rpm (typically 30mph in 4th gear auto). He contacted the dealer and arranged for a road test with a technician. The technician was very concerned about the noise and didn’t want me to drive the car. Owner was loaned a courtesy car for a week. It took a week for dealer to get a decision from VW technical department on what to do next. He had in the meantime checked that the software had been correctly installed. He was told to install version 9978 on 22nd July. He did this and the car was returned to the owner with a copy of the report which stated “road tested again, all OK”. It was a very hot day when he collected the car, but when he was able to reduce the aircon fan speed he could hear the noise again. It was slightly less loud, but still within the same rpm range. He returned the car to the dealer on 11th August, having run the supermarket fuel onto reserve as advised and refuelled with Shell Regular Diesel and was again lent a courtesy car for 2 days whilst a further investigation was carried out. He was informed that version 9977 had caused complaints on some other cars and that the 9978 version was working OK on my car, the noise now being “injection noise”. He was advised to again run the fuel onto reserve and refuel with Shell, which I did. There was no reduction in noise. It appears that the 23R7 recall instruction to technicians did not include a road test. In short, after two attempts, VW has failed to reinstate the car to its previous noise level, whilst performance and economy appear to be OK. It was previously a very smooth engine, with no roughness at any rev. range. [Repeated HJ suggestion is to try running on higher cetane Shell V-power or BP Ultimate.]

3-9-2016: 8th report of post emissions defeat remap on a Tiguan: "The 2012 Tiguan has just has the emissions fix done for VW by Lookers and it seems down on power. It is holding onto lower gears in the auto box when it would have changed up and drops down a gear at 70 mph on long slight inclines. Both are new characteristics and the engine sounds more strained. We have just been to a Country Show on short grass and parked on a hill and there was a smell like hot or burning clutch which again is new. Car has done 33,500 miles and is booked for an annual service." ["Hot" smell might be the DPF actively regenerating.]

Had remap done on our Passat 3weeks back (140tdi Bluemotion estate 2013 )everything seems fine if anything the mpg has improved even when towing a caravan.

SLO76    on 6 September 2016

Haven't seen any sign of the motoring press intending on carrying out independent tests pre and post modifications.

We have a Polo 1.2 TDi as a second car and I'm highly reluctant to allow the recall to be carried out on it without independent evidence that I'll not be worse off as a result.

Aside from the worrying threat/bluff from the DVSA that any cars which haven't had the update will fail any future Mot as they introduce new legislation to accommodate the issue I fail to see what owners will gain from complying, especially as VW are not offering any compensation even a discount on service or another token gesture.

I'll be avoiding until it is certain that the Mot will become an issue or there is independent proof the car will not be adversely affected.

I have a 2015 Skoda Superb 2.0 TDI cr which had a software update. Since update its also 'rattles' like the tiguan reports. It's most noticeable around 1500 rpm on a light throttle. Car has just spent a week at dealers who carried out various tests sending data to Skoda HQ technical team. Their conclusion is that everything is OK. Engine is definitely noisier despite what skoda's tests may show. Dealer told me that my software update was 9979, after those mentioned, yet still causing noise. Very disappointed and has ruined my experience of the car. Now deciding my next course of action to escalate this for a resolution.

Simon Mo    on 20 September 2016

i have a 2013 VW Tiguan 2.0tdi 4motion DSG and it has also recieved 2 software updates
the knocking noise at low revs is still present, the engine seem strained going through the gears, engine vibration is fed back into the interior trim causing a humming noise in the trim
there is a deffinate loss of power the dsg gearbox is totally messed up cannot drive the car smooothly like before the updates
worst thing is that the dealership i bought the car from has gone into denial mode and claims the the figure shown on the diagnostics are within the parameters
so now i have contacted customer care on VW uk again and sent the car to another dealership which their master tech tookit for a a 5min test drive has confirmed all my issues
this is the 6th time in gone in for these issues
But VW technical do not share information on what the previous dealers has done to the car and everthing is in a closed loop only VW technical will decide what to inform
Now i'm still waiting after 1 week for VW technical to confirm its caused by the emmissions software so can get them to authorise Mobex for an like for like car for me to use

Anisah    on 9 December 2016

I recently had the emissions changes and the car is starting to have noticeable issues with the car giving out more revs. Also with my Tiguan being an automatic it all of a sudden loses power and does not start. I have had previous bad experience with VW, so I am dreading to see what they say to this issue!

Have the issues been resolved yet with your car?

Simon Mo    on 7 January 2017

No not all !!

i even took it to another dealership to try to resolve the problem, which was going great with the head technician agreeing to me that there was a problem.

Then after a few days they said its been put through the diagnostics and they said my car to be operating within the parameters set by VW

So therefore they are not going to investigate it any further and they also told me that VW uk were refusing to pay the dealership for any work carried out on my car.

I am so fed up with VW i cannot express my utter disgust with this company enough

i found that using Shell fuel helps a little bit rather than the supermarket stuff

Charles Harkin    on 22 September 2016

As the owner of a 64 plate 2.0L TDi DSG Sharan I find all this all a bit worrying. The Saran is never mentioned in the list of cars needing the fix but I got the dreaded VW letter saying it is. As far as I understand some Tiguans have the reduction catalyst and use the Adblue fluid and some do not, so are all the problem cars Adblue users or all not ? It will take much less tweeking of the firmware in a car with a reduction catalyst than one without. I would find it strange if they both got the same update.

If I understand the chemistry of NOx production in the engine ( I may in fact not understand it ) its due to the excess of oxygen above what is actually needed for complete combustion that causes NOx to be produced. It reduces fuel consumption and gives better torque but makes NOx in the precess. The point Im getting round to is that reducing the fueling will make this worse not better, with even more excess oxygen to react with the nitrogen. Could it be that they turn down the boost at the problem revs putting less excess oxygen in to the engine and this is causing the noise, loss of power and vibration ?

In petrol engines its the very lean burn engines that produce the most NOx. As CO2 goes down NOx goes up.

I will not be going anywhere near a VW dealer till I am confident they will not ruin my car.

   on 1 October 2016

My 11 plate golf 2.0 tdi blue motion has developed the knocking as described, not noticed the increased fuel consumption but I've been doing more round the town driving than before, so it's up anyway. Knocking more prevalent when engine cold and when higher torque required around 1500-2000 revs going up hill. In with a mate who's having a look at it now, but likely to be complaining bitterly to VW early next week!!!

Nicola Mawson    on 4 October 2016

I've had the emissions update done on my Audi A4 2.0 TDi and I wish I hadn't!

It was meant to be done on the Thursday but their computers were down so I had to go back on the Saturday and as its a 50mile round trip, the garage put in £20 of fuel because of the repeat journey , so I was quite happy with that and drove home.

Didn't use the car for a few days but the next time I did, the judder from the engine when it was cold was appalling from first gear and up through all the gears, a constant judder which you have to really press the accelorator and it then goes but change gear and the judder is back until you accelerate again. Once the engine is warm this juddering stops.

The dealer has had my car for three weeks now and have done numerous tests but I have been told today that Audi UK technical have said there is absolutely no way the update could have caused this problem as the update only removes a piece of software! Apparently it is pure coincidence that my car now drives like an old tank when the engine is cold!

I now have to pay Audi for them to investigate what is wrong with the car; technician has mentioned injector, compressions in the cylinder head has also been mentioned but I absolutely disagree that this is pure coincidence.

I don't see why I should be paying for an investigation into a problem that WAS CLEARLY CAUSED BY THE UPDATE!!!

The car went in perfect, it had the update and the £20 of fuel and now it's not perfect; the only coincide is the bit in the middle!

So, if you haven't had the emissions update, I wouldn't bother!

Arthur Leewis    on 4 October 2016

My 2012 Passat Estate 2.0 TDI Bluemotion has had the update a week ago, and I am NOT happy!! Before the update the listed 170 Bhp was clearly there, and the car would accellerate smoothly. I now have after the update, a sluggish, underpowered donkey, that VW apparently does no longer care about. The dealership does not appear to have the correct expertise to resolve these problems, and indeed, after the update the car sometimes cuts out when going down a hill with the throttle slightly open. This, in my view, is a dangerous issue. Also the horsepower that has disappeared needs to be returned, I bought a car with a certain specification, and if that spec is changed for the worse, some compensation must be due......

we have exactly the same problem

My VW dealer at Norwich refuses to accept since the upgrade its not there fault

They have refused to take the car back and reprogramme with the software before the upgrade saying VW will not allow !

Anybody with the same issues on the passat 2014 please contact me

HI I've got the same problem my number is 01473780786 please contact me for a chat regards Matt

I got my 2010 VW golf 2.0 tdi done on the 20th August and it came out with the engine rattle and the mpg is way lower than it was. It went back into the dealership who done the update and they had it for nearly a week. They rang to say the car is ok to pick up. Over a month later and my car still has the same problems. The dealership have said they can't do any more and having been in contact with VW customer services they have also said there is nothing more they can do so overall I have been fobbed off by them both. I've been in touch with Motorcodes to file a complaint so let's see what they do.

ukoracle    on 12 October 2016

Following the emissions 'fix', I had same 'clatter' issue and reduced power at low revs on my 2 year old Tiguan. Local VW dealership confirmed that that had been a few complaints about what they called 'pinking' and that Tiguan's needed to be re-done with revised engine mapping to get around the problem, just had this done, and does seemed to have worked. Begs the question though that if VW knew there was a problem with the original fix for Tiguan's, and so produced a new mapping then why did they not recall them again. I'm really not impressed as I was also getting increased fuel consumption (too early to say if 2nd fix has solved this), my car has depreciated more in 1 year than 2 years for my last Tiguan, and yet VW position is that no compensation should be paid to UK owners as we haven't experienced any loss..............!

I have a Skoda Superb 2.0 litre TDi which used to be a 170 bhp version .
Foolishly I let Looker's Eccles do the recall and god knows what it is now , marginally faster than a milk float !
All the torque in third has gone the car is dreadful to drive and the economy is drastically down by around 7 to 8 mpg . The car still has 46 K miles to run until the end of the lease so that's about an extra £900 of diesel.

VAG are maintaining that nobody has complained about this issue . I have however just found out that there is a Skoda emissions complaints team at Milton Keynes so that seems to indicate that there is no change in their policy of lying to everyone both Governments and the poor sods that drive their remapped cars !

If you haven't had the recall / remap done do not under any circumstances agree to let them do it it will kill your car !!!

Geoff Hampson    on 25 October 2016

I also took my Tiguan in for the recall in July. Noisy like a worn out taxi at low revs when pulling also some loss in fuel consumption. Real shame as before the upgrade it was faultless.
I have now taken it back to my VW Dealer. Now Firstly they said they were aware of a problem and had a software fix. Day two and they are changing injector under VW instruction but the need a day three to continue. They haven't got a curtesy car available till Thursday so who knows whats going on.

   on 27 October 2016

I am about to book my Tiguan for the fix but god i am not happy at all. Is there any group where those issues are discussed? Even the lawyer companies who started to approach VW owners for a group to sue VW are doing nothing.

Rich kilborn    on 28 October 2016

Took tiguan 2tdi bluemotion in for emissions fix now has pinking rattle noise when accelerating under 2000 rpm and seeing a drop in mpg by 10.would be interested to see if anyone is happy with vw fix.Just waiting to here back from dealership

   on 28 October 2016

Thanks my Audi 2.0 TDI was due in next week but i've canceled the software update for now think i'll change it next year but it will not be German or french hope you all get your cars sorted.

Phil fennessy    on 1 November 2016

Same issue with a Golf shudder and splutter at low revs when cold almost like a fuel contamination when the engine runs at higher revs or is warm then the engine runs better. one instance of the engine running on after the ingnition was turned off

   on 2 November 2016

Gt tdi golf mk 6 2010 same as above had it done 2 weeks ago and now does not run well at all

   on 4 November 2016

I took my 12 plate polo in for the software update , and it came back totally gutless , labouring in every gear . Not happy !!!

   on 5 November 2016

Just had the emission fix done on my 2.0 TDI SE Bluemotion DSG (Auto) VW Touran 2014...I am experiencing similar if not the same problems as experienced by the Tiguans in this article.
Rattling at low revs and loss of power - not happy about having to use more expensive Diesel.
VW seemed to have "cured" one problem and created another!
VW dealer seemed quite excited at giving me a mug, a pen, a VW badge and sweets in an expensive box. I pointed out that it wasn't the same as a £10,000 refund as our neighbours across the pond got.
He pointed out that VW had done nothing wrong here in the UK
WRONG answer... how about upsetting numerous VW customers?
Won't be buying another.

Tiguan TDI 140bhp DSG auto, 2011.
Just had software upgrade for emissions done' and the engine seems smoother and up on power, looking at past posts I must be very lucky,or has the software changed??

KayJay    on 5 November 2016

My Audi A4 170 went in for its first mot in sept. I explicitly told them not to change the software, when I collected it they told me "we have upgraded the software but it has no effect, it only effects it when it is in cycle beating mode". I tried to explain the illogical statement but they did not understand, I decided to give it some miles and see. I always leave the trip calculator and never reset it, it indicated 52mpg over the previous few thousand miles. I reset it to see the new mileage. I have since done about 1500 miles and can never do better that 50mpg and the average is down to 46, so I have lost 10pc.

Power also appears to be down. Power is subjective but the chassis used to torque steer on full gas in 1st and 2nd, now it never tugs and struggles to keep up on fast junctions.

I visited my dealer today but they say the cannot do anything and the changes have no effect on the car (no effect, why are they needed?). My main complaint is they changed the software when I explicitly told them not to. They insist they cannot set it back. It's wrong that they can tamper with my car against my permission.

I have little hope of Audi doing anything. They appear arrogant and do not care, I have never been sent a letter of apology for their miss-selling or need to change the software for cheating in my car. My only recourse is that when replace both of our main cars in 2017 they will not be VAG products.

Anybody had any issues with engine management and emision lights coming on post fix? Mines a 2.0 tdi a3

jeff normanton    on 26 November 2016

My Tiguan was 'fixed' and 17 miles afterwards the 'Catalytic Convertor' warning light came on. I returned the car to JCT 600, Wakefield who diagnosed that the EGR valve was sticking and needed replacing, and would cost about £1500.

After seeing the service manager and explaining that the car had done 63000 miles without issue I could not accept that it was 'just a coincidence' as he called it and 'nothing at all to do with the update'. After further discussion he agreed to 'contact the brand' and see if they would accept any or all of the cost of the work.

Later he came back to tell me that VW would provide the parts free of charge and I would only have to pay for the labour, 9 hours at £100 per hour which I think is exorbitant.

They managed to get rid of the warning light, they could have taken a bulb out for all I know, and I have been driving the car for 2 days without it returning so I am reluctant to go ahead with the repair.

I have since spoken to a solicitor who is dealing with calaims for compensation against VW and have been informed that it is quite common and not to pay more than £300 maximum.

Has anyone else had this issue.

Wilskonsk    on 30 January 2017

Yes! About 150miles after a full service on my A5 2.0tdi 170 Quattro, at which time they carried out the emissions recall, the 'Emission Control System' warning light came on.

I took it back to the service centre and they tried to charge me £60 for diagnostics. I refused to pay and they gallantly agreed to waive the fee. They say that they then run the diagnostics and it showed an issue with the DPF. So they carried out a forced regen, cleared the fault and said to come back if there were any issues. Amazingly - no charge!

Well, earlier today on my way home, 12 days after the regen, the light came back on. So tomorrow I'll be taking it back. Again.

I find it strange that if it was a DPF issue, that it wasn't the DPF light that came on.

Both times the ECS light came on was whilst driving slow in traffic, in a high gear/low revs.

I have a horrible feeling this is issue is going to be a long and painful experience!

blackislemikey    on 31 January 2017

Anybody had any issues with engine management and emision lights coming on post fix? Mines a 2.0 tdi a3

Yep, me! I thought it must be the DPF so took it to get a flush but the ECU said the EGR valve was malfunctioning (blocked). Now taking it to dealer to get the ECU read by them so I can ask them if VW/Seat are willing to pay for something that should last longer than 30k miles. £700-800 for a replacement EGR after 30k miles, criminal. I have a Seat 1.2 diesel which had the reprogramme about three weeks ago.

I have just had the emissions fix on my bluemotion / 4 motion Tiguan manual gearbox SE. Bought new in sept 11 and only done 26k miles and following the fix it seems o.k on performance but it has a growling noise when putting your foot down and when lifting off on the throttle at certain revs. It seems a throatie / growling noise more like a sports model noise. They told me it would be a 2hr fix but reading on hear it says only half hour as it is only a software change. My VW dealer said drive it for a week and see what happens and then give them a call if it is still noisy. They also said they have had no other similar noise problems reported at there dealership. After all of the lengthy wait for the update it is very disappointing and all I can say I won't buy another one and my fear is I won't get a good p/x value.

Hi Laura, have VW resolved anything ? My car has been back 3 times and they say it is O.K. but my car is still noisey. Would be inerested if thay have fixed yours. regards Peter E

4motion    on 10 November 2016

I have a 2014 vw tiguan 4 motion manual. I had the emissions update performed a few weeks ago, and noticed a dramatic consistent drop in mpg.
vw state that they have had no issues with the update, and that i would have to prove my loss of mpg, which is impossible.
I can't be the only one???

   on 13 November 2016

Seat exeo 143 deisel. Down on torque at low revs and gutless. Stalled on me going round a roundabout in 3rd as no pull . Lost power steering. Not good.

Seat refusing to provide any in gear rev/torque/ power delivery graphs before and after and I have been referred to either German or Spanish authorities as apparently uk authorities have had "nothing to do with this!

Contacted the chair of the uk transport committee 3 weeks ago ...no response. phoned 2 weeks ago ... no reply.

This reeks of another cover up. If engine performance not impacted. Why the secrecy over before and after performance?

Had my 2011 Tiguan 2.0l TDI R-line, DSG box upgraded last week (5th Nov) all going good, put Supermarket diesel in last night, took a run in it today with noticeable lack of power at low revs, hunting for fuel etc not good.

Phone dealer who stated they have had no problems with re-mapping but have arranged for it to go back to them for a couple of days.

Can anyone please advise on what the best way to proceed legally etc. If this issue is not resolved?

My wife had her 2010 SEAT Ibiza FR 2ltr 140 diesel software update and since then if there's a frost when you start the engine from cold there is really loud knocking noise coming from the engine. Booked in with the dealership to look at.
Anyone else experiencing this?

Hi. I have exactly the same problem and am about to take it up with Seat. Have you got anywhere ?

Euron Jones    on 20 November 2016

I know this is a thread for the 2.0 TDI,but I am experiencing very similar issues with a 1.2 TDI 2011 VW Polo. The software was updated in October and since then it lacks power and the idle speed has increased from ~800rpm to ~1200rpm. Significant vibrations at idling can be felt throughout the whole car and steering wheel.

The car is now at my local VW dealership, who have accepted that the idle speed vibrations are a problem but have not yet identified the cause. Various diagnostic checks have shown no issues, and they have now sent a fuel sample to be checked by an independent expert. The car has been with them for over a week.

TimDavis    on 23 November 2016

I've got an early 2013 Tiguan SE TDI 4motion and a letter saying an upgrade is avilable arrived two weeks ago.

Haven't booked Anything yet. I think I will ask my VW dealer to provide a couple of references from people who have already had the upgrade. If they refuse then I will write to VW UK and copy in my MP.

Any one else got any suggestions?

I've got an early 2013 Tiguan SE TDI 4motion and a letter saying an upgrade is avilable arrived two weeks ago. Haven't booked Anything yet. I think I will ask my VW dealer to provide a couple of references from people who have already had the upgrade. If they refuse then I will write to VW UK and copy in my MP. Any one else got any suggestions

Don't have it done until software is proven. Jan 2017 software still has problems.

Last week I traded in my 58 Plate Audi A4 2.0 TDi Multitronic for a 60 plate VW Passat 1.6 TDI Bluemotion. The Passat was juddering when changing up to 5th & 6th gear around 14-1800 rpm. Garage replaced injectors and informed me problem still exists! They contacted VW who said it requires a software update to which I said if it's the Emissions update it will require a Flow Straightener as part of the update. I also noticed the Passat was returning around 48.5 mpg vs 49.4 with the Audi.
After reading this thread I hope they don't return the Passat with a rattle and lower fuel consumption! I have informed the dealer if the vehicle is not to my satisfaction I will be rejecting it and requesting my Audi to be returned (Audi has not had the update carried out).

My 2 litre 140bhp Seat Exeo had the update a couple of weeks ago. I've not noticed any difference in the way it drives but the MPG is down by 5-10%. I contacted the Seat dealer which did the work and was told it was the first report received of this nature after completing over 100 updates. I asked if I could have the settings returned to what they were before and this possibility is being followed up. If I'd read the blogs on this website beforehand, I definitely wouldn't have bothered.

Shall we get together into a FB group and collect evidence about emission fix? Nobody does anything. Even the claim lawers went quiet.

Jeff McCann    on 24 November 2016

I had my passat 2.0tdi serviced and the recall done back in july, thinking at the time of changing the car and if it had all recalls done it may make for a better sale price. what a mistake!!!.

i have abit more information for the readers here, i have had a few months to analyse the problem further.

the car developed a rattle from the engine at low speed 1100-1500rpm this is at 30mph in 4th gear, sounds like pinking in a petrol engine. i have narrowed it down to the top end of the engine by making sound recordings with a microphone at different points on the engine.

Power is down since recall, more noticable on long uphill routes, again this is more noticable at lower engine speeds 1100-1500rpms.

DPF regenerations... this is happening a lot more than before the recall, prior to recall it would regenerate only about twice in 12 months or 16000 miles. now it is regenerating every 160-200 miles at best.

economy is down between 6-10mpg over 3800 miles since recall.

one thing i have noticed driving the car is that during one of the frequent DPF regenerations, the rattle noise disapears and normal power is resumed... thinking about the dpf a little more... it collects soot? if it needs to regenerate so often then there must be more soot build up?. CO2 and hydrocarbons create soot, so their quantity in the emissions must have increased since recall?.

i have taken the car back to 2 different dealers now 5 days off work to let them have the car and all they have done is check for error codes and then re-run the recall software. i have spoken to VW customer service and they said the software "will not affect the economy or power output, or cause increased engine noise" and get this one... they said it has no affect on the nox emissions just makes it easier to detect!!!. complete t***!!!. they ended the conversation by suggesting i took the car in for investigation work as there could be a mechanical fault.

now since the weather has cooled to below 5c here i have noticed another change. whilst the temperature is low the rattle goes away and normal power is resumed. earlier this week the temperature rose to 7c and the rattle returned. i read that the new software only changes fueling settings between 5c and 18c at lower than 5c and above 18c it is deemed to possibly cause engine wear. there have been a few reported cases of engine damage in the last few weeks costing owners near £2k to repair, caused by incorrect fuel timing.

according to 2 VW dealers they are not allowed by Head office to return the old software. i read on a few forums that some owners are having independant help and a couple have swapped ECU's in a test to see if the same problems could be replicated on a different car. some difficulties with programming immobilisers but once done the car that had NOT had the recall developed problems, and the one which had the unchanged ECU put in ran like new again. proving that the problem is in the new software.

if some sort of group action can be arranged to get the cars reverted back to factory settings then count me in. i have a lot of names of others who have the same issues.

Vw are putting inert gas into the engine this is why your engine Pinks

Colin Beetle    on 2 February 2017

Hi Jeff, I'm another statistic you can add to the EGR failure list- see my post just now. Beetle 2.0 TDI EGR failure 5 weeks post Recall Fix applied. Car Stalled at 40MPH, putting wife & son at risk in traffic !

DeChristi    on 25 November 2016

You can add me to that list Jeff McCann, how many others are having issues? I'm surprised this hasn't been picked up by the press a bit more.

We bought a 2013 2.0tdi (140) Tiguan DSG 4M BM etc last year and it drove beautifully. It was so quiet I kept forgetting it was a diesel. Since the 1st update in July it sounds like a tractor and the engine strains to go up hills. Used to get 45-50mpg on long trips, now we're lucky if we can get 40. About 30 around town.

Took it in the Bristol VW dealer who ran the usual diagnostics and couldn't find anything to report, so apparently they can't contact VW direct if they don't find a specific issue. They let me go without paying for the diagnostics, so I reckon they don't want to get involved until VW finds a fix. They also told me they think people are noticing pre-existing issues since the update and told by VW not to admit faults caused by the software update. Can't be a coincidence though, so many cars having the same problems.

Have logged a call with VW directly, but getting minimal response.

There are a few forums with posts from people with similar issues (like: www.vwaudiforum.co.uk/forum/showthread.php/177267-...5), but no admission from VW that there is a problem with some cars, except in Auto Express in August. Here's a copy of the relevant page:

drive.google.com/open?id=0By1Xj5dk9Nm5RzczVDRRbENm...U

Shown this to the VW dealer but they don't know anything about a "revised software update". Have also emailed it to VW direct, but still no response.

Interesting what you say about the temperature affecting the settings. Will check the car next time it drops under 5C again.

In the meantime, will start a complaint through Resolver and see how far that gets.

Hope the engine doesn't blow up before this gets sorted. If that's already happened with a few cars, then the owners need to speak up. All I have read about them so far is hearsay.





Jeff McCann    on 16 December 2016

DeChristi.

sorry for late reply been busy at work. how are things going with resolver?. not had chance to contact them yet.

i know of 6 cars that have had engine failure, over 20 more with EGR valve failure. as to how many are suffering the same issues after the recall i have a list of names gathered from various forums at the last count 1290 names and growing by the week.

getting an email response from VW is like finding hens teeth. it took 6 weeks for my first response, they just wanted my address and daytime phone number. gave them this and another 5 weeks went by, now they are saying i am not showing as owner of the car on their system. which i am assuming that is just a delay tactic hoping i will go away.

i have read the VW Audi forum pages and collected names from all posters there. just wondering if one of the no win no fee solicitors would get anything done for us. maybe worth a try?.

Suki kaur    on 30 December 2016

Hi Jeff

My problem is that i am awaiting my so called fix, but after my car going into limp mode and engine management light coming up it is in the garage, awaiting diagnostics ?? EFR valve may need replacing.

My question is that although it is still awaiting update have you had any reports of customers awaiting software update and as a result this happening, could the two be related?? Please also add me to your list as at the present time when i have put these questions to vw it is all cloak and dagger. It is already day 3 without a car!!!

Jeff McCann    on 2 January 2017

Hi.

not heard of any EGR failures prior to the recall. apart from one old lady ignoring the prompts from the car to drive it harder to complete the DPF regeneration. i would contact the garage and insist they dont do the recall. the week before christmas i removed the EGR from a friends golf and it was so clogged i was surprised the car was running at all also the intercooler and pipes were full of thick black oil luckily a good clean and all was good again. this car had the recall done in october where a intercooler hose was replaced and at that time there was no build up in the pipes or intercooler.

i have added you to my list. VW have had to set on more staff to deal with the problem of complaints after the recall so lets hope that will prove a point to them and we get some support, still waiting for a email reply to one sent to customer service in November. will be on to them again next week.

hope all goes well for you

Jeff

David Lyth    on 26 November 2016

I have a Tiguan 2.0 Diesel Bluemotion and had the software update.
Throttle response has worsened to the point that their appears to be quite a power losee. At light throttle around 2000 rpm the car hesitates giving the impression something is wrong. It also seems noisier.
Prior to this the car went beautifully, I was impressed with what a modern diesel could do. It cost me 25k new.
I will now sell it and no more VW for me. They are lying b******s who have walked away from their customers.

ChrisLawes    on 27 November 2016

Vw tiguan 2011 2.0tdi DSG went for upgrade last month wife reports it idles too fast pulling at lights and noisy she also said it was worse on fuel than before. I took it for long drive this weekend (not that i didn't beleive her) and totally agree wildl be talking to garage on Tuesday simply not good enough Volkswagen.

Angela Nixon    on 29 November 2016

Hi all.
Golf owner here and i have been one of the unfortunate ones. my car had the recall done back in July and i have been battling with VW ever since to get the old software put back. but 3 weeks ago in the outside lane of the motorway a sudden heavy metalic clunk total loss of power. i did manage to roll onto the hard shoulder. as it was late evening i got the car taken home.

my husband said NO MORE VW... he found a recomended VW/Audi specialist and we had the car taken there. he stripped the engine and found that the new software had caused fuel starvation and caused wear. the entire top of the engine "Cylendar head" had to be rebuilt and a new cam belt. all work done in 3 days. but the ecu software was put back to Factory settings. now the car runs great just like it did from new. but the cost of the repair was £1890. now i need to try claiming that back from VW. my solicitor says i have a good case and sees no reason why we should not get paid out for the repair and some sort of compensation.

Chris Gillie    on 29 November 2016

I have drawn vw attention to these issues and this thread as an example . Before having it done I asked for an explanation and what assurances I could get that it wouldn't happen to me.

Despite weeks of chasing and writing to director Alison Jones I'm just getting stonewalled.

It is quite obvious there is a problem with the fix which he are trying to brush under the carpet. I suspect they don't know why this happens to some cars (some owners claim their cars are fine) but not others.

There is already a group on this I'll see if I can share.

Next stop my mp suggest you all do the same, there's a select comittee looking at this
If its not escalated they will brush it off as a few individual cases while convincing the govt the problem is solved

Ady McConnell    on 29 November 2016

VW Blue Motion 1.2 bough brand new in April 2014.
Absolutely no problems wit it at all, has only done 5000 miles in two and a half years.
Went in for software upgrade on 27th October.
Next day, pulled (or attempted to pull) out of a junction on a roundabout.
No power at all and nearly taken out by a lorry.
Car felt like it was trying to start in second gear.
Result?
Car went back to dealership on 2nd November and it is still there.
Dealership are waiting for VW to pick up and look at vehicle.
Courtesy car from VW?
Not a chance.
Having to sort out a hire car from Europa Car.
Although VW are paying the rental Europa Car are phoning on a weekly basis to swap the vehicles they are lending to me.
Had enough and have now rejected the vehicle as have lost complete and total confidence in the product.
Something needs to be done as I thought I was just unlucky with my vehicle - did not realise so many issues had been caused to other cars with the upgrade.

Edgar Polo    on 13 January 2017

My 1.2TDI Bluemotion Polo is showing very similar symptoms after the recall, having had none since purchase. Supposedly has had another update to fix but have lost confidence in the car. Wondered if you had managed to get anywhere with VW with regard to a solution, and if they accepted your rejection of the car?

   on 30 November 2016

I have a Tiguan 2012 TDi DSG Bluemotion. It has just had a major service and 'updated' software after recalls. It is now rattling as if there is a hole in the exhaust. The econony has dropped by 50miles per tank, the accelerator is uncertain at low speeds, gears appear to hanging on. I am a professional driver and know this is not the car I initially bought. I will contact VW tomorrow and let you know how I get on.

TimDavis    on 30 November 2016

BBC Watchdog Program?

I haven't had my 2013 Tiguan 2.0TDI 4Motion SE updated yet (received the letter about 2 weeks ago and having followed this forum and being refused any references from other upgrade customers from my local dealer, a refusal to let me test drive a post fix Tiguan, and no guarantee either, then I will be REFUSING the upgrade as well. I do think I am one of the LUCKY ones.

My Tiguan is out of warranty now so ... it'll never be visiting any VW dealer ever again (I hope). I have a mechanic that I can trust as opposed to the VW brand that has already admitted cheating once and I'm not sure what they are playing at now!

Why don't you all send your stories to BBC's Watchdog program? If enough people do this they must surely cover the problem. They did for the Zafira and there weren't 2.1 millions affected cars for that.

Just a thought.

2010 2.0tdi 4motion tiguan .

my tiguan went in for the emission fix to jct 600 wickersley on the 14th november,
after using the car for nearly three weeks i can now honestly say the engine has lost torque will not pick up speed in 5th and 6th gear from lower speeds as it used to before,the engine exhaust note is louder like a booming sound just as though one of the windows have been left down slightly,the fuel consumption is down by 6mpg this is not using the in car computer but tank to tank,overhaul iam really upset as this was a great car before, i contacted jct600 and explained, they are taking the car back on the 20th december to look further what they are going to achieve is anyones guess, i will keep you upto date with the situation,

jsteventon    on 3 December 2016

I have now received the second letter relating to the required upgrade to the software. I will be intersted to see what the third one states. I have no intention of getting the upgrade done and I now take my golf to an independant garage to ensure the EM software is not changed.

   on 4 December 2016

had my 2011 A3 for 2 years. lovely car never a problem.
had the emissions update at Audi in Nottingham.
2 weeks later emission and emu light came on and car in limp mode.
took car to local garage who carried out checks and said need a new EGR valve
had this done.
2 weeks later emissions and emu light on car in limp mode. took it back. they can find no problem all sensors within limits.
looking at other sites it appears other Audi owners have had the same EGR valve problem after upgrade.
seems likely I have paid for a repair that is down to the upgrade
also particle filter light keeps coming on, only had this once in 2 years prior to upgrade, despite doing several long journeys. is the upgrade causing more particle emissions from the engine?
cannot believe this is just coincidence.
will contact Audi in Notts for response.
will post the reply

paul wilson    on 4 December 2016

update on my egr seat say it is a coincedence and refuse to do anything unless i pay full price for repair they tell me they have no reported cases which they expect me to believe this from a company that lied in the first place . soon as can afford new car i am getting away from any car to do with VW customer service is a joke

DeChristi    on 5 December 2016

The emissions "fix" engages the EGR valve much more often than before, so it is not surprising that these are failing, especially after they haven't been as active for the years before the update. Our cars may have been performing much better before the update, but would also have been spewing out high levels of emissions. Reducing the emissions without affecting performance can't be resolved cheaply with a software fix, despite what VW say. They should leave the cars alone, or install a urea injection system (AdBlue) which they obviously don't want to due to cost.

I'm going to write to my MP, Watchdog, the Consumer Ombudsman, Slater Gordon (the emissions lawyers I've registered with) and suggest everyone else affected does too. I've also contacted Auto Express who published an article about a "revised update" for the Tiguans, which either doesn't work or doesn't exist, but doubt they will be able to do anything about it due to the threat of lost advertising revenue if they anger the beast.

Charles Harkin    on 5 December 2016

The emissions "fix" engages the EGR valve much more often than before, I suspect you are right about that DeChisti as it explains the raft of failures after the fix. There will be other changes as well no doubt, fueling, injection timing and boost pressure. Some manufacturers have been found to only engage the ERG for the first 20 minutes of driving then its turned off to " protect the engine ".

Not sure the urea pump is the whole solution though. My late 64 Shaean has the Adbue system but is still listed to have the software upgrade or more acuratly software downgrade so I dont know what to expect, but it will not be happening till I do know what to expect.

Where I live and drive is in rural areas where NOx is not a great problem, t does not build up in the atmosphere like CO2 as its life is measured in a few days. in cities though it builds up around high buildings and causes the health problem. VW are far from the worst at producing NOx, its the way they cheated thats the problem, other makes cheat but cheat with in the rules and produce as much if not more NOx the VW.

BigAndyG    on 5 December 2016

I had good look around on the web after my second (ignored) reminder and found someone who had actually had his car dynoed before and after the update. I too do not know why none of the motoring press or Watchdog or... haven't done this. Anyway the results are quite damning and back up a lot of what has been said here about ~1500-2500 rpm and loss of power and torque. I have graphed these plots (as best I can) and that's exactly what they seem to show. I sent them to Audi and they wouldn't engage on showing me their test data but just trotted out the old "maximum torque is not affected" line - which is true but very misleading for driveability etc.They also mention an increased EGR rate! I've put the graphs at this link:

Here's the text of Audi's response:
------------------------
Thank you for your recent contact to Audi UK. Please accept my apologies for the delay in our response.

I note your request for further information regarding what the software update does to your vehicle, specifically, you have raised concerns regarding the potential effects of the software update on your vehicle’s power and torque.

First of all, I would like to confirm that the Volkswagen Group has developed a software update for 2.0 litre diesel engines affected by the NOx emissions issues, such as your vehicle, and that this software update is now available to be implemented in your vehicle.

In response to the concerns you raised, the software update, which will replace the existing software in the affected vehicles, takes advantage of advances in diesel combustion technology that were not available at the time the affected vehicles were manufactured, such as that which you find in newer engines (for example the current EA 288 engines). The pure labour time for this software only update should be around half an hour.

Thank you for providing the spreadsheets. It is very difficult for us to comment on these graphs without more information, for example where the data set was sourced from, who carried out the testing, the conditions such testing was carried out in, how fast the vehicle was accelerated during the tests, which gear was used and other such variable factors.

Notwithstanding the spreadsheets you have provided, I would like to assure you that the German Federal Motor Transport Authority (the KBA) is performing independent and rigorous tests of the implementation of the technical measures in the affected vehicles, to ensure that the measures have no adverse impact on the performance of those vehicles. I can also confirm that the KBA is testing the impact of the technical measures on the affected vehicles’ torque across the range and at different rotational speeds.

In this regard, the KBA has provided its final written clearance for the implementation of the software update for your vehicle model and has confirmed that the update has no impact on CO2 emissions, MPG, engine performance and maximum torque, and noise emissions.

In addition to the KBA’s tests, Volkswagen is also carrying out intensive safeguarding programmes internally in order to ensure the high quality of the approach being taken.

If you require further reassurance, we will, following the software update and on request, provide you with a Certificate of Completion which reiterates the KBA’s written clearance that the successful implementation of the measure does not adversely impact the engine performance, fuel consumption, CO2 emissions, maximum torque or noise of your vehicle, and that all values related to the type approval for your vehicle remain unchanged.

In response to your request for a more detailed explanation of the “advances in diesel combustion technology”, I can confirm that the update includes a revised fuel injection pattern, meaning that the number of injections, as well as the timing of those injections are changed. An additional fuel injection phase has been added but as it is formed from part of the fuel quantity of the main injection there is no negative effect on fuel consumption. Specifically, this additional fuel injection phase takes advantage of technology that was not available at the time the affected vehicles were manufactured.

In essence, the affected vehicle’s injection phase has been split from a single injection into multiple injections which results in an improved burning process in the engine. The software update also increases the affected vehicles’ Exhaust Gas Recirculation (EGR) rate, which results in lower nitrogen oxides (NOx) production. Improvements in the combustion process ensure that this increase in the EGR rate (which lowers NOx levels) does not have a detrimental impact on particulate levels.

I hope this information is sufficient for your concerns and offers you reassurance that the software update will not adversely impact your vehicle.

Kind regards

Executive Office
Audi UK

Aye right......

c haase    on 5 January 2017

Chaase. I see that vw have mentioned the EGR valve last of all this is the bit that has caused all the problems

mhm    on 31 January 2017

I have measured soot collected by the DPF for the past 6 months. Following the upgrade, soot collected and regenerations increased 2 -4 fold. Clearly Audi's claim that particulates are not affected is not correct.

Have you had any further responses?

Martyn

mhm    on 9 February 2017

Have you got your original letter or email saying that particulates don't increase. I've checked mine before and after the fix and they go up 2 - 4 times. I'd like to show that they lied.

Also, did you get anywhere with the source of your power and torque graphs that would be really good info of we could prove the Providence. Strange, VAG don't have to prove anything

Richard Whiteside    on 5 December 2016

Our 2011 Tiguan 2.0 TDI 4WD DSG had the ERG Valve replaced with a VW OEM part by our local garage, not a VW dealer, in September 2016 after 68,000 miles having gone into "Limp Home Mode."

4 weeks later the car went to VW for the emissions update, and for about 200 miles seemed OK. Then the problems started, rough running, misfiring and the DPF regenerating 5 or 6 times in a 4 mile journey filling the cr with fumes The RAC diagnosed a "Software Fault" and emailed a report to us.

Once we showed this and a copy of the invoice for the ERG Valve to the VW dealership we were provided with a Golf 1.4TSI Auto as a courtesy car and advised the dealer we were not going to return this until the Tiguan was restored to how it had been for the previous 70,000 miles.

A week later, the Tiguan was returned to us. VW had replaced all 4 fuel injectors and further updated the emissions software. 2,000 miles further on, the car is running better than before the initial software update. However, this was not without having to convince the dealer that none of the faults were there before the update.

Anisah    on 9 December 2016

I am glad to hear that VW resolved the issues you were faced with... I'm currently having the same issues and will need to go back to the VW garage very soon! Hopefully they will be able to resolve the issues.

Richard Whiteside    on 27 January 2017

And here we are at the end of January, the DPF regenerating 3 or 4 times a week and filling the car with fumes again. Also lots of smoke coming from the exhaust under acceleration which didn't happen befor the upgrade.

The car is due back at the VW dealer on 8th February, in the meantime the car cannot be driven. I feel a "To Be Signed For" letter going to te Dealer Principal as the car was running perfectly before the update is now doing anything but.

Was it of merchantable quality and fit for purpose when we bought it? I don't know and will see if my legal expenses insurance might cover demanding VW buy it back like the company are doing in America.

As soon as it is sorted, it will be sold, probably replaced by a Mazda of some sort.

Richard Whiteside    on 28 January 2017

Update on last night, we have joined the Harcus Sinclair Class Action the Honest John link for this is

www.honestjohn.co.uk/news/volkswagen-emissions-sca.../

Richard Whiteside    on 29 January 2017

The car would shortly need a new cam belt, 4 tyres and new front shock absorbers, so purely on monetary grounds is Mazda 3 has been ordered as a replacement with delivery due in March.

Petrol, so no turbo, DPF etc. What isn't there can't go wrong!

I will however report on the efforts of the local VW dealer to fix it.

DCE    on 9 December 2016

I have a 2.0 GT TDI 140 had the update done in September car ok for about 200 miles has gone into limp mode 4 times in the last six weeks showing fault code P0403, sometimes clears if you restart the engine, otherwise I have a code reader to clear the code.
I had no problems previously when I bought the car in June 2013 and had covered 30,000 miles.
P0403 is a erg solenoid fault.
Not sure how to proceed with the VW s******s.

Chris Gillie    on 12 December 2016

For those experiencing problems or anyone else who has concerns there is a facebook group (closed you will need to apply to join) for people with similar concerns.( there are probably others

it is called "the Diesel Customer Forum (emissions Scandal)

We have a manual gear 2012 Tiguan 2.0 TDi BlueMotion. The car went for the software upgrade (in Portugal it is mandatory) and returned with obvious lost of power at low rpm 1000-2000. It becomes quite obvious cruising on motorway in 6th gear. We took the car to VW dealer and the first mechanic that tested the car confirmed the motor lacked power at low rpm. The dealer called the car back twice more for testing and sending information to VW factory. After this process VW just informed us the car does not have any anomaly (notice they don't say the car has the same power, they just say it is normal).

This is the second VM fraud. After lies to governmental agencies, now VW lies to their customers.

   on 13 December 2016

My volkswagen golf 1.6 tdi bluemotion 59 plate went in for the emissions software update on thursday 8th december 2016 next drive I took it on it went into limp mode with loss of power saying engine fault take to workshop. So phoned vw explained the situation, took it in for diagnostics later that day I get a phone call saying the EGR Valve is clogged and needs to be replaced costing £1300. I said i will take it to my local mechanic they said they would do it for half price!? Bearing in mind I just had a full service 2 months prior and car was running smoothly never had a problem before.

   on 14 December 2016

Reading all the comments above, my Skoda Yeti 2.0 was such a pleasure to drive, since software update I have experienced all of the above issues, no longer a pleasure to drive, it's not the same car and I actually want to have the software reverted back to its original configuration. Someone out there must have the know how, willing to pay !!!

I regret allowing Skoda to take the car for its update it's ruined the driving experience! Fuel consumption up, I use the premium diesel, throttle not responsive, engine rattles a lot, pulling away is laborious and at times dangerous as the pull away not what it used to be and potentially with fatal consequences. Is this a plot by the government to make us get rid of our diesel vehicles? That's why this issue isn't being reported by the media, who knows ??

Very Disappointed Skoda Owner !!

DCE    on 14 December 2016

skoda owner.

From what I can gather , the mod done is just a software one and requires the fitting of a baffle tube in the air intake after the air filter. (Which took 2.5 hrs?) on line there is a video of this work I think it took no longer than 15 mins.
The strange thing is on my previous MOT test the emissions were to clean to read because on my mk6 golf there is a rev limiter, so after the mod nothing will change,as they can't rev the engine to get a reading perhaps an independent VW / Skoda garage could return your vehicle to the original set up?

Have you contacted Skoda?

Tiguan bluemotion owner

Had the software changed 2000 miles ago and after putting up with reduced mpg and rattling pinking noise i decided to go back to the vw dealership who did the software update , they told me to give the car at least 1000miles for the new software to work properly, (this was not explained before), when i said i have done 2000miles they oferd to have a look in 5 week time, in the meantime the mpg as reterned to the pre software change or even better one trip recorded over 60mpg driven carefully but still got the pinking rattle noise which could be cheap fuel.

Jeff McCann    on 17 December 2016

Hi.

the rattling pinking noise is the part you need to worry about, it is wear taking place due to badly programmed fueling. as i have said in a past post here and on several other motoring forums. you say your MPG has got better recently... one question where you live has the outside temperature dropped below 5c?. if so that is why. the new software is only active between 5c and 18c. outside this range you have the old software "factory settings" this info was provided by an ex-VW service technician.

the best course of action would be to keep pestering the dealer and vw customer services for an agreement to get your old software put back. i know they will refuse as they have with me on several occasions. but if enough owners do the same then coupled with the threat of changing brands maybe something will get done.

good luck every one

I had the update done yesturday on a 2013 Skoda Yeti 2.0l diesel. Noticed immediately that it is down on low end power, sounds noisier with a pinking sound as though the fuel mixture is a bit too lean. Will see how it goes, but if I am not happy I will be back to get them to reinstate the old software - if that's even possible? Wish I had done some research before I agreed to the update.

Golf mk6 2.0 TDI P0403 code error.
Rang the main steelers to day over problems with limp mode,after emissions mod,they want me to take it in for a diagnostic test,wanted me to pay £96.00 for the privelige,they have agreed to do the test free of charge ,when I said I wouldn,t pay.

They have already ruled out the EGR valve before even testing it! then when I mentioned it is a common fault, that the EGR fails she agreed with me, then hinted that Volkswagen may help with the cost.

If you have a EGR delete do you have to remove the DPF due to regeneration issues?

Just had the modification done on our 100,000 mile Seat Ibiza 1.6 TDi along with a service and other work. Have to say on the drive home from the dealer first impressions weren't good. I'm sure I heard pinking (which I didn't even realise diesel engines could do). It generally felt less responsive and clearly hesitated a couple of times on the change up to second at low revs. Hoping it magically sorts itself out... MAE


Manbatius    on 22 December 2016

Well after a couple of weeks with the "fix", I have never seen the onboard computer display such a low MPG in the two years I have owned it. Early estimations are -5mpg.
Mine is the 2.0 TDi. It drives as rubbish as it always did, so no real complaints there at least!

   on 30 December 2016

Our Tiguan Bluemotion lost power at low rpm after the software update. After complaining and 2 technical analysis we were called one more time to make a new software update. This new update did not bring any difference, the engine is still pretty much dead at around 2000 rpm, which makes it need to use 5th gear a lot when driving on highway. The current status is that VW is telling us that the car parameters do not show any anomaly and they will not do anything. So basically the strategy of VW in europe is to ruin their customer engines and then give then the finger. Brilliant strategy, I am sure all of us VW customers will accept this with a smile.

Glad to have read all the above comments.

Have this morning received the letter to update my 2011 Skoda Yeti 170bhp reassuring me that I will have no change in performance or economy. ( hmmmmm )?

To date Having had the car from new it has given me over 3years of pleasurable faultless driving and therefore I certainly have fears of letting Skoda play with.

As the saying goes ' If it ain't broke don't fix it '.

My only question is are there any repercussions in not having the so called upgrade carried out?

Cheers Geoff

VW Passat 2.0tdi 170bhp (originally)
So I got my "it's your turn" letter through the post today. Some may well criticise me for this but when I bought the car I had the dpf deleted and ecu remapped so was wary about letting VW anywhere near it. Thought I'd do a bit of searching to see if anyone with similar mods had taken theirs in anyone and what the outcome was.
After reading everyones comments on here I'm not wary, I'm full on going to refuse this until they drag it there under court order.
But just out of curiosity, what do you think they would do to my dirty smogger if they got their hands on it? Insist it's returned to factory spec at my cost is my assumption, which I will pointblank refuse. All in all I think I will be steering well clear of any VW dealerships until I have better idea of what they plan on doing.

Wacko Jacko    on 8 January 2017

Hi, I'm considering having dpf removed when it requires replacement. Has the removal increased low end torque significantly? Thanks

   on 31 December 2016

Our 1.6 Golf TDI had the emissions fix. It was previously fine and now loses power with the engine cutting out when driving at 30mph. It is back in for investigations but nothing found. A the minute VW won't reinstate the existing software. Has anyone been successful with similar requests?

Jim Watt    on 31 December 2016

This morning my 2013 Skoda Yeti 170 bhp received its invite to the "Make your car worse" party, needless to say having read all the comments on here I am going to decline the invite. I am so sorry to hear all your problems, but glad that you have all taken the time to explain the effects that this mod has had upon your vehicles.
I feel that as more readers take on board your feelings on this matter they will not go ahead and have the mod done. I sincerely hope that all your issues get resolved and you you see justice from the bandits at VW Group.

Found this site by chance and am glad i did, my 2011 140 vw passat had upgrade sept 2016. Did not notice anything issues with car initialy, but now after a couple of thousand miles have noted that average fuel consumption has dropped approx 10%. Have had car over 4 yrs so i know what the average mpg should be. Not noticed any pinking sound which is mentioned by several owners. Have also noted dpf regeneration does happen more frequently which also leaves an intermitant smell of exhaust fumes inside the car. Will contact dealer about concerns and await responce.

NattyB    on 1 January 2017

Well i wish i had read all this before i took mine in!!! Bought my vw golf mk6 tdi at the end of September of a private seller. I got my emissions letter a few weeks ago, so i had it booked in for last wednesday. I got my car back and there were no problems. I went to start it today and a few seconds after it started, it started stuttering, felt like it was going to conk out on me!! So i left it a few minutes and tried again and same as before!! Think im going to be ringing vw up tomorrow for them to fix and they can f*** off if they think im paying a penny for it!! It even says on the emissions letter you get that it there will be ' no negative impact on engine performance, maximum torque, fuel consumption, noise and CO2 emissions.'.... bs!! I would advise everyone to NOT have the test done., maybe this is the reason they lied about the emissions in the first place if this is what happens when its done.I bought this new car in hopes that unlike my old car i would not have to be constantly taking it to the garage because it has some sort of problem and up until this, it was running fantastic with no issues!!

Geoff O'Sullivan    on 2 January 2017

Well hi!!! I am a Skoda Octavia 170 DSG Jan 2010 owner and I have been thinking about the upgarde(?) After seeing this site and reading the Briskoda web site I am not at all sure about having my car fixed (made worse!) At the moment it pulls well at 1500-2000 RPM and does about 43.3mpg overall. Do I want it to Pink? Do I want worse mpg? Do I want driving issues? No so looks like I will not be having the upgrade then!!! Geoff

Paul Earley    on 3 January 2017

I have a 2014 177 bhp diesel tiguan, with DSG gearbox and with 36,00 miles on clock. I have had from new.
It went in for emission up grade on 13th December and when I received it back it felt different immediately. There was a definite power lag at about 1500 revs.
When I put my foot on throttle there was a noticeable delay followed by the gearbox changing down before power kicking in. It was jerky not smooth.
I reported it to the garage who said they would look at it and so is booked it for today. 3rd Jan 2017
I phoned VW after the upgrade to register my annoyance and ask them what they were going to do about it and got absolutely no where. They were not interested, kept repeating a prepared message and would not let me talk to anyone and kept referring me back to the garage. All I want is the car to perform as it has for the last 2 years. Its not my fault this has happened it is VWs, and the are already stone walling.What a professional way to behave

do not have your VW re-mapped this would turn on the EGR Valve this recirculates exhaust gas through your engine, it will destroy your engine.

gasengineer    on 4 January 2017

Wow - what a thread.

Just had the letter to take my 1.6 Caddy van in so I think I'll be holding off.

One thing that occurred to me is that when VW dealers are investigating all these problems reported - why can't they just revert to the old mapping software and test the vehicle to see if the issues go away or are pre existing as they claim.

Seems so obvious....

c haase    on 5 January 2017

I have also received the letter from vw asking me to come in for the update I have a vw caddy and will not be taking it in after reading all the treads in here. It seems all the vehicles on here and else where are having the same problems. At the moment there is no law in place that requires you to have the fix,but it looks like they will put a more stringent mot test in place soon so your vehicle will fail. I've just had an mot so I have 1 years grace to make decision.

   on 4 January 2017

Message to gas engineer from recently retired gas engineer.

As I understand it the current mapping of our engines/ecu's is that it recognises when is in test mode and automatically 'down powers' to give an in accurate but more preferable emissions reading.
This is why we're expected to go to the trouble of having our vehicles fiddled so that it gets Volkswagen off the hook.

Now, here's the interesting bit.
If, like the manufacturers are stating is true that our performance, economy and reliability will not be affected with the upgrade then why did they need to cheat in the first place?

Having read the impressive list of grumbles above there is no way that I'll be having my vehicle interfered with to satisfy their needs.

By doing so you risk everything but gain nothing.

Again I wonder what the outcome will be for those like me, who chose to leave well alone and stay away from the main dealers who have their own agenda....?

This is nothing to do with emissions This Is falty components EGR valves .my Skoda Yeti has done 30.000 miles Egr valve stuck £1,000 to replace it

   on 4 January 2017

Stephen, north east England.

As the owner of a 2013 Skoda Yeti 140 I too received all the letters regarding the 'Service Action', which I ignored. Just before Christmas I received a call from my local Skoda dealer inviting me to take in my car for the emissions update. I said I did not want to bring it in as I have read too many reports of engine problems since the fix. I was then informed that I DID NOT have to bring it in to have the update done if I did not want to.I asked if there would be any problems with the car passing the MOT, they said no.

I also asked my local MOT station who said there would be no problems. Cars with these engines have been MOT tested with no problems since 2012, and will still continue to pass as the regulation have not changed.

Owners of cars who have had the fix done and are now unhappy with results and cannot get anywhere with the dealers could as a last resort take there car to a Re- mapping centre. They can re-map the ECU, not only returning the performance to how it was, but improving it and also the fuel economy. Not sure of the cost, at a guess 2-3 hundred pounds. One such place is UNIT 9 REMAPS, Horden nr Peterlee.

Hope this is of some use to all affected owners.

Wish we had found this site earlier.
Golf 2.0 TDI EA189 Engine
Had car from new (Oct 2011) 36900 miles to date. Full service history by VW agents.
Software update due to emissions scandal carried out in October 2016.
Just 1300 miles later on January 4th 2017 the engine fault message lights up on dash and car goes into limp mode (no advance warning). Fortunately only doing 30mph.
Driven to VW agents for 3 days where the oucome is - Excessive carbon build up within EGR valve. Replaced and refit, updated software to suit. Total Price £979-09.
As a goodwill gesture a 90% reduction against parts and labour will be applied, leaving us to pay £100.
Fought hard with all at VW agents (1.5 hours) to avoid paying anything, only to be advised the car would not be released until settled.
Assured the car would have no further problems. Watch this space !!!
Could have been a totally different story if we had been doing 70mph on the motorway when we went into limp mode.
Lost all trust in car.

When vehicles go into limp mode they become extremely dangerous has anyone had an accident yet or is that what it is going to take before something is done ?

Got my letter last wk take it to local vw dealer in Edinburgh. 59 reg 2.0 Passat bluemotion the car drives superb best car we've owned it since new asked a mot inspector about future mot said don't bother getting the recall done. There is to many horrific story's of vws driving like crap after recall. So the decision I've made they can stick there recall up there f***er. I will stick with my 65mpg and my non pinking 189 engine thanks very much vw.

kdhuk    on 9 January 2017

I have a Touran 1.6 TDI (2011 model) - I had the EGR valve replaced in April 2016 at a cost of £510 inc VAT (partly offset by free parts from VW) and have just received the notice to have the emissions service action done on its EA189 engine.
Reading through this thread it seems the engine adjustment makes the EGR valve more likely to fail again - at least I have a 2 year warranty on this work(?)

RyanD    on 9 January 2017

I've just had the remap on my 2015 Tiguan 177 tdi DSG. Not noticed any rattle but have noted a substantial reduction in mpg. In some instances, according to the trip computer, this can be over 10mpg difference to pre-fix. I've been driving it far more gently since the fix on an attempt to get the vehicle at least over the 40mpg level....but can't! Today on my usual commute I averaged 35mpg rather than the normal 44-47mpg.

Also noted that the kick down on the DSG box can be slow.

Booked back into VW tomorrow for further investigation.....

Jan K    on 9 January 2017

I have a Audi A5 Sportsback and had the car booked in today to have an interim service and the emissions fix done. Luckily 2 weeks ago had a Slater&Gordon update email saying recent issues with the fix and so cancelled the update today. Asked the dealer anyway how would I know if the s/w fix had indeed been done ie what is the rev level code of the new s/w? He couldn't answer. Does anyone know what it is?

My experience on s/w levels when I bought the car after it being 9 mths old was dire...I asked for the 2014 Sat Nav update when I collected it only to find it was still 2013. I returned the car for the 2014 update. I picked it up after they said ' all done' and when I got home it was still rev 2013. I went mad! They apologized and finally loaded up 2014 version. Net the customer had to check twice. So conversely, how do I as a customer know if the emissions fix has NOT been done? I would like to go back to the dealer and ask them to plug in their diagnostic computer and read me what it says....but what should it say for a car without the fix / car with a fix?

DeChristi    on 10 January 2017

This website can tell you if the update has been applied AND Audi have updated their record of your car: www.audi.co.uk/owners-area/emissions/check-your-ca...l

The software update is more like a patch and doesn't change the ECU version number, so you probably won't be able to tell unless you try to re-install the patch and it tells you it has already been installed.

andrewspe    on 10 January 2017

My 2.0 tdi is down on mpg and total lack of power below 2000rpm and sounds like bag of hammers when cold,

strangely at around 3000rpm there is a nice boost, more than before.

stuck with it though, just paid £1500 for egr and cooler failure literally days before emissions update was booked in.

as has been mentioned by audi official person above, update increases egr usage etc... i don't trust the card reliability wise now reading these comments.

i would happily put my name down towards any compensation claim

Just discovered this thread as I had called vw ref the rattle and 'plinking' sound on acceleration in my golf 1.6 tdi post 'fix' 2 weeks ago. They were concerned that I do not drive and should call my roadside assistance to take the car to them asap. They can't see it until Monday but I'm now really concerned !

   on 15 January 2017

Just to update on my seat exeo EA189 issue with lost power and torque at low revs. I have been told by Seat that no data on "before and after" performance data is available.

However I am now seeking data from KBA in Germany. They initially sent response advising SEAT should provide data. I sent them some e-mail exchanges with SEAT where they say no data is being made available to customers. SEAT have also refused to reinstall old software settings.

Have also contacted chair of transport select committee ( afraid to say nothing coming back from her).i' ll let everyone know what the KBA say if I get anywhere.

This all stinks of another cover up. I think the motoring press are too busy counting their add revenues to care about investigating this. At least it's clear who's side they are on. I sent info to auto express ... they are not interested in corporate cover up....I haven't bought their magazine since.

The Construction and Use Act at one time had a catch-all provision that 'you cannot modify a vehicle if it then presents a danger to its owner - or other road users'.

Talk of limp modes, hesitation etc. makes you basically wonder if this "update" makes the car safer to drive ...?

John Morri    on 16 January 2017

I had my Golf fix on 5th December. On January 1st, whilst driving on the motorway, the car went into 'Limp Mode'. The VW dealer diagnosed a failed EGR Valve. It cost £1150 to fix and VW paid 90%. The car now seems to be performing as before.

Anyone noticed there DPF cleaning more since the emissions update??? I have a 11 plate Passat auto 170 bhp. I've had the car two years and I've only had this problem since October not sure if it's connected but a loud fan comes on at the end of a journey 6-7 times now.

I think it's my DPF cleaning and has not completed the cycle. I've always been cautious about DPF filters as it my first diesel so I give it a good drive ( I have a heavy foot). So thought it was strange it was happening to me.

On Vw website it states that you have to leave the vehicle in S MODE and drive for 15 mins keeping revs between 2500 and 3000 which I've done and twoce and still keeps happening. On avaerage I do two motorway runs a week at off peak times so I get to drive at constant speed.

I wonder if the update has effected DPF cleaning has anyone noticed this since update??.

Driving hard is not the answer and higher revs are only aplicable if the warning light has come on. Its counter intuative but exhaust gas temperatures are higher at lower revs, speeds above 38mph are whats needed for normal regeneration. Hard driving uses more fuel and produces more soot so the whole system works harder. Once engine has fully heated up a steady drive of 10 to 15 mins will allow regeneration if required.

VW's advice :-

VAG DISESEL PARTICULATE FILTERS

Courtesy of David Bodily Volkswagen Technical Support Specialist

Diesel Particulate Filter (DPF)

Detailed below is important information outlining the function and features of the Diesel Particulate filter which all members of your team need to be aware of.

Diesel particulate filters are becoming more commonplace on diesel engines, particularly sizes 2.0L upwards. This is in order to reduce the exhaust emissions as required by European legislation.

The prime reason for a DPF is to reduce particulate matter entering the atmosphere. Particulate matter is found in the form of soot, which is produced during diesel combustion. The DPF traps most of the soot which would normally travel down the exhaust and into the atmosphere. The DPF can hold a certain amount of soot, but not a huge quantity and therefore it needs to go through a process called ‘regeneration’ in order to clear the soot loading. When the soot goes through a ‘regeneration’ process it will be converted to a much smaller amount of ash. The ash is non-removable. There are two types of ‘regeneration’, passive and active.

During long motorway journeys, passive regeneration will occur. This needs no intervention from the engine control unit. Due to the raised exhaust temperatures on a long journey (temperatures between 350 and 500°C), the procedure occurs slowly and continuously across the catalytic-coated (with platinum) DPF. The catalytic-coated DPF is situated close to the Engine, therefore the exhaust gas temperature is high enough (500°C) to ignite the soot particles. Due to this soot is burned-off and is converted into a smaller amount of ash.

Active ‘regeneration’ is when the ECU intervenes when the soot loading in the DPF is calculated to be 45%. The procedure lasts for about 5 – 10 minutes. Specific measures are taken by the ECU to raise the engine exhaust temperature to above 600°C, these include switching off the exhaust gas recirculation and increasing the fuel injection period to include a small injection after the main injection. The soot particles are oxidised at this temperature.

The ECU will trigger a regeneration process, if for some reason this is aborted, ie. customer slows down, stops etc, the process will be resumed when regeneration conditions are once again met, above 60km/h (38mph). This will continue for 15 minutes.

If after 2 attempts of 15 minutes, a successful regeneration has not been possible, the loading will increase. At 50% soot loading, the ECU will continue to maintain maximum exhaust temperatures of 600°C to 650°C to cause a regeneration process. The system will try to run a regeneration process for 15 minutes. If unsuccessful, the system will repeat this process for a further 15 minutes, if still unsuccessful, the DPF light on the driver display panel will then be lit.

The owners handbook states, the DPF symbol lights up to indicate that the diesel particulate filter has become obstructed with soot due to frequent short trips. When the warning lamp comes on, the driver should drive at a constant speed of at least 60 km/h for about 10 minutes. As a result of the increase in temperature the soot in the filter will be burned off. If the DPF symbol does not go out, the driver should contact an authorised Volkswagen repairer and have the fault rectified.

At 55% soot loading the DPF light is lit on driver display panel. At this point the customer should follow the advice in the handbook. If they ignore this information and continue driving the vehicle until the soot loading reaches 75% without successful regeneration, additional warning lamps will light up. At this point the customer will also be complaining of lack of power, etc.

At 75%, regeneration is still possible with the use of the VAS tester. Only when the loading is above 95%, is it necessary to replace the DPF unit.

Operating Status System Response

45% DPF Load Level 1

Regeneration from 60 km/h onwards

("See operating manual")

75% DPF Load DPF, SYS and MI lamp

95% DPF Load Replace the DPF Unit

The Warranty department has confirmed that if there is no fault on the vehicle and DPF regeneration has been unsuccessful due to the customers driving style and the customers failure to comply with the instructions in the handbook, DPF replacement will not be paid for by warranty.

Common causes for complaint

• Frequent short journeys – Regeneration conditions are not met.

Not recommended for sale in the Channel Islands and inner city driving.

• Customers who continue to drive the vehicle with DPF light on – Continued

driving with the DPF light on and without successful regeneration results in

excessive soot loading of the DPF, to a point where it is above 95% loaded.

At this point regeneration is not an option and replacement of the DPF is

necessary.

• Fault 18434 particle filter bank 1 malfunction – Common fault code. This does

not only relate to the DPF itself, but the entire exhaust gas handling system. This

can be caused by defective temperature sensors, pressure sensors, additive

system components (if applicable), poor connections, wiring issues, etc.

Important Information

• Before diagnosing a problem vehicle or attempting to perform an emergency

regeneration, it is important to obtain a full diagnostic log and read out relevant

measured value blocks. These MVB’s contain important information on the

condition of the DPF system and are essential in diagnosing the fault. When the

DPF light is illuminated, it does not necessarily mean that the DPF requires

regeneration. For further advice, please contact Technical Support with the

information from the diagnostic log and MVB data.

• If a problem vehicle arrives with the DPF light, the engine management light and

the emissions light on. If during your diagnosis and reading of relevant MVB’s,

you find that the soot loading exceeds 75% (but is still below 95%), an

emergency regeneration procedure must be performed with the VAS tester.

Further to this, the customer needs to be educated. They need to understand

why the lights have appeared on the dash panel. Their attention needs to be

brought to the owners handbook instructions, so that they are aware of what the

DPF light means and what to do when it appears. This should prevent

unnecessary repeat visits for regeneration purposes.

I have also found that as the car gets older 30K+ miles, you will notice that the regeneration takes place more often.

ALWAYS, check your oil before any long journey, as DPF regeneration can use a fair bit of oil.

Some questions and answers that may help;

Question: The glow plug symbol is flashing. Why? What should be done?

Answer: The DPF regeneration has not been completed during normal

driving and now DPF has reached its maximum saturation at which it can

still be regenerated. The limit value depends on variant and Model Year,

but is in the range of 105% - 125%.Possible causes for this are:

a.) Frequent short distance journeys, i.e. high soot loading while at

the same time regeneration of the DPF does not take place because the

conditions necessary were not fulfilled.

b.) Frequent

interrupted regenerations, i.e. the engine was switched off during

regeneration. Applies to short journey drivers who have at least

fulfilled the conditions for triggering regeneration. If the glow plug

light flashes, the vehicle

a.) Engine running since start for

longer than 2 minutes.

b.) Calculated saturation higher than 80%.

c.) Coolant temperature over 70°C for at least 2 minutes.

d.) No

DPF-relevant faults stored in system.

e.) A defined vehicle speed

threshold must have been exceeded (e.g. for >80% loading, 100 km/h)

Question: Under what conditions is regeneration

interrupted/ended once it has started?

Answer: Normally when

regeneration has been successfully completed, or:

a.) After a

maximum regeneration time (20 - 25 min.).

b.) If the engine is

switched off or has stalled.

c.) If the engine is left idling for a

long time (5 - 10 min.).

d.) If 1000°C is detected by the exhaust

temperature sensor.

e.) If during regeneration, a fault is detected

on the components relevant for combustion (injection/intake system).

If

a regeneration is interrupted once started but before it has been 50%

completed, the glow plug lamp flashes on the next engine start (cold or

hot) and regeneration begins again once the operating conditions (see 3)

have been fulfilled.

Question: How long does complete

regeneration take? a.) In the most favourable case? b.) In the least

favourable case?

Answer: a.) Under constant conditions, i.e.

the exhaust temperature necessary for regeneration always lies above the

required value, for example during motorway/cross-country driving, the

average regeneration time is 10 minutes.

b.) Vehicle

conditions such as long down-hill descents, frequent driving in the

low-load range (city driving, idling) allow the exhaust temperature to

fall. If the conditions for triggering regeneration were fulfilled, the

active regeneration time can be extended up to 25 minutes (depending on

engine type). If complete regeneration is not possible within this

period, the regeneration will be interrupted.

Question:

How does regeneration affect the oil life?

Answer: On each

regeneration or attempted regeneration, a certain diesel fuel amount is

injected into the engine oil which reduces the oil life. If the "INSP"

light in the instrument cluster comes on, the engine oil is exhausted

and must be changed. Failure to do so could damage the engine.

Yes i have noticed more regens also during a regen the car is more responsive,mpg is better as it was befor the software update, i am guessing during a regen the egr valve is cut of.

i have the same problem with vw passat 1.6 bluemotion 2011 model it went in for a remap at vw came with the back with the fault

Aaron Duignan    on 22 January 2017

I have an Audi A4 B8 and had the software update done on Thursday. They returned the car to me with the engine light on. I didn't even drive the car after the update. At first they couldn't figure out why the light was on. On friday they contacted me to tell me an air intake actuator would need replaced and it would cost me £600. They told me that the update is not related to the fault and that it is just a coincidence. I don't believe this and won't pay. the car is still at Audi and I will be contacting my solicitor Monday morning to see what my rights are. Audi are a disgrace and they costumer service is worse. How are they getting away with this in the UK. Anyone any suggestions or advice? It would be much appreciated

TimDavis    on 23 January 2017

It's sounds to me like you have a very very strong case here. The garage have clearly broken the engine and they should fix it.

I would immediately send a recorded 'letter of liability' from a solicitor to the garage and demand that they put the car back to it's original state. They will probably want you to make a contribution and will fix it 'without prejudice' in order to avoid any possibility of accepting liability.

Why not search and join the Facebook group 'Volkswagen dieselcustomer forum', where you'll find a lot of people with the same problem

Trevor elson    on 25 January 2017

Just had our Tiguan in for its " repair", result is our once powerful easy to drive this 2.0 tdi, 170 BHP vehicle is now gutless, there's a distinct engine noise ( pinking) below 2250 rpm and frankly it is not what we bought, we loved the car before it's "fix" but now you need to drive it like a petrol engined vehicle, revving a diesel is just wrong but the only way to get any performance from it now.
I'm unsure if joining one of the class actions is the way forward or simply taking the small claims court route. Clearly the sales of goods act is relevant, we simply do not have the vehicle we were led to believe we had paid for - all to save VW's reputation.......

My 2012 which had the VW recommended modification in August is now a rougher engine which has reduced milage per gallon reduced from an average of 45 mpg to under 40,

VW garage suggest they will approach VW HQ to see if there is a new computer modification.

I wonder if I can get the modification to convert to the original ?

Ok so i took my car - Golf 2.0 GtTdi Mk6 - in for the emissions update on the 28th December. As soon as i got it back it felt awful to drive!! The power was lacking, no torque, lagging in gears, it was a hell of a lot louder, it had a clanky rattle type noise to it, my revs were up by about 1000-1500 and i could be doing 40mph and be in 6th gear!! I also had on two occasions were I started it up and after a few seconds it felt like it was going to conk out on me, i had to turn it off, give it a few mins and start it up again, which made no difference until i gave it a few revs and it was ok!! I txt my mate who is a mechanic and he said it could be my ecg valve.. I rung the VW dealership that did the update on my car and told them all of the problems i was having, it was 2 weeks until they could book me in and i was told that i would have to pay £60 for them to look at it, at this point i kicked up a real stink, the woman that i spoke to got a bit quivery after my outburst and said I wouldn't have to pay!! I then spoke to VW uk and told them everything, they said that with it going in due to the emissions update i will not have to pay. So I dropped it off 8am 2 week later, they had it 2 days. They rung to say that nothing has come up on the diagnostics, no problem with ecg valve (there is, my mechanic showed me, im guessing they don't get their hands dirty!!) and no warning lights, so a technician was going to take it home and bring it back next day. So still nothing!!!! I then picked it up in the afternoon of day 2 and went on a test drive with a tech, he said it pulls brilliant and everything seems as it should. They said that if anything does come up again to bring it back but at the mo there is nothing they can do with it. So i drove away, 5 mins into the drive I realised that the b*****s had put the old software back on my car and obviously not told me given its illegal (i think)!! Powers up, torques back, its quiet, revs are back to normal and it slides through gears like butter!! I am 100% sure that they got in the car felt all the probs it had and realised its going to be costing them and me a hell of a lot and i would be continuously taking it back til it was sorted, and thought, b***** to that lest just put the old software back on. This is the best result i could of asked for and my advice to all is... do not deviate, threaten them with contacting VW uk and complaining ( my friend used work at VW as a mech, he said they really dont like VW uk getting in touch, it looks bad on each dealership. Everyone will get a different result depending on the dealership and i guess i looked out. Good luck to all that are trying to get their car back to how it was, i hope the outcome is as good as mine.

Your lucky I have taken mine back 3 times and they say it is illegal to put back the software. I have written to VW complaints and guess what you never get a reply. Thouroughly disgusted with VW attitude that all is well and no clatter at 1500 - 2000rpm and not noisy, like exhaust blowing - I am now getting rid of mine.

Do not take your car for the recall whatever you do do not do it you will regret it forever

c haase    on 29 January 2017

The so-called recall turns on your EGR valve this will put your car into limp mode as they are faulty components this is why they turn them off in the first place nothing to do within missions

Hi Folks
Golf 1.6 TDI 2012 Model - was running perfectly before the update last week, now the car is hunting when at idle between 1000 and 1500 rpm, the radiator fan comes on at the end of each trip never did this before, I am very disappointed in VW UK. Don't get this update done - you will regret it!

Roger Thompson    on 29 January 2017

I bought my 2012 VW Tiguan SE TDI Bluetech 4Motion in April 2016 and enjoyed 6 months of great motoring. I took it for its 23R7 EA 189 emissions software upgrade on 26/10/16. On 30/12/16 it failed to start and the AA diagnostic brought up P0403 EGR valve fault. A local mechanic attempted to flush out the problem so I wouldn't have to pay up to £1000 to get the valve replaced, but the problem re-occurred today (29/1/17). Looking at all the other posts about Tiguans and the emissions software upgrade, I'm wondering if mine is another instance of the same problem. The AA guy noted there were only 36000 miles on the clock, and thought it strange that the EGR valve should be clogged up already.

Luis Alves    on 31 January 2017

I have a SEAT Ibiza 1.6 TDI (105 hp, year 2010) and I received the letter to go to a dealership and repair the emissions's problem. It's not optional. Here, in Portugal, I have 18 months to go. If I don't, the car won't pass the test to circulate legally. I don't want an engine with more rattle sound, poorer fuel consumption or other problems. What can I do? Help, please.

Coffee23    on 1 February 2017

Hi all,

Just a heads up, KEEP YOUR CARS AWAY FROM MAIN DEALERS!

I have a 2009 Passat 2.0 tdi (140) and it recently needed a service, I booked it in and took it to the garage and they never asked me if I wanted the software update and when I went to collect the car they never told me that they had done it, however the car has not been performing like it used to at all, slower, with a heavy foot I would get wheel spin going from 2nd to 3rd and from3rd to 4th the car would push you back into the seat...

Now it's like well, MEH !!!

I honestly am not happy at all and don't know what to do TBH.
The fan comes in after 50+ mile trips, every 300-400 miles the DPF clears out (think it's that as she smokes for about 5-10 mins while driving).
MPG was around 55 now I'm lucky to get 50, and louder engine sound compared to pre service.

Service was done just before Christmas but I though it was just me with the changes, but after reading on here and then checking the VIN it is saying that the engine has been updated (NOT WITH MY PERMISSION).


Fred.

mhm    on 1 February 2017

If the fab stood on after you do and t turn off the engine, it's a sign that the engine is regenerating the DPF, and you have switched switched off part way through the regeneration phase. Before the "fix" my car regenerated every 500kms. Now it's every 150 kms

Colin Beetle    on 2 February 2017

I would be very interested in a group claim !

VW Beetle 2.0 TDI (EA189)

Emissions Recall work done on 21/12/2016

Engine Management light on & off from Jan 25.

Engine Stalled in gear at 40MPH in traffic !

Missfire/stutter 1500-2250rpm

Burning smell when parked after run.

Took back to VW Dealer today - EGR Valve diagnosed, £1750 but VW will meet 90% of the cost ! but will give me 2 year warranty on the EGR !

I asked if this was as a result of the Recall work, they said 'no' as all that did was fix a NOX sensor ! yeah right. After reading others, this is no coincidence. I like the idea of a 2 year warranty on my EGR for £175, but that's not the point is it ?

Stuart Read    on 3 February 2017

It is interesting to read all these comments.

I have had nothing but problems since I took my 2015 Audi A5 in for the Cheat Device to be removed. Audi continually tell me that they have not had any reported problems with any other cars at all!! REALLY!!!

I was suspicious when I started getting the letters for the recall of my A5. Audi were insistent on every letter I received, that there would be no change to MPG, Power or Emissions etc. I was thinking if that was the case, why did it have the software on in the first place, why not supply a car with it already removed?

So for a month before it went in for the device to be removed, I logged the MPG on the same 12 mile journey to a from work. I also ran it up a stretch of motorway, with the speed control set at 75mph.

After the fix I did exactly the same.

The difference was this. Before the cheat device was removed, my car would average 47mpg on the journey to work. After the device was removed, it is now averaging 37mpg. On the motorway test, it would happily sit at 55mpg, since the fix it is down to 47mpg. The difference is equal to about 80 miles less per tank of fuel. There also seems a lack of power, and the engine noise is different.

I went to my dealer, and gave them this information. It was swiftly passed on to their "emissions team". I started getting phone calls from Audi UK telling me there was nothing wrong with my car. Every phone call I had, I was given a different excuse, and informed my case was closed. The excuses were as follows.

The wheels are turning freely so there is nothing wrong.

Data shows nothing wrong.

We said in our letter there would be no change, so there is nothing wrong.

200,000 cars were tested worldwide, so there is nothing wrong.

The VCA in the UK actually tested your model, so there is nothing wrong.

So I checked all of this out. Audi admitted they have no Data for my car prior to the fix being carried out. I telephoned the VCA and KBA to ask about the 200,000 cars being tested. They both told me only a handful were tested. I have an email from the VCA, stating that they were only tasked to check a couple of Skoda's in the UK.

So its been b******* after b******* from Audi UK, who just say there is nothing wrong. They haven't even taken my car in to look at it!!!

Another brand loyal customer they will be losing....

Mike7777    on 5 February 2017

Golf 2.0 tdi gt had the software fix in late October. 3 weeks later engine light, limp mode. EGR diagnosed and replaced. 3 weeks later same again, EGR codes. Had the original replacement done by local garage because vw wouldn't see it for 2 weeks and also said that the fault was purely coincidental. Now that the car is in limp mode again the garage don't know what's wrong with it as "it can't be the EGR, it's just been replaced". Could it be that a brand new EGR has been clogged up in such a short time as a result of the software? I'm about to find out. So far vw have denied any link. This is going to be painful....

piranz    on 5 February 2017

Having been the owner of an Exeo was delighted with performance and mpg ! But upon first hearing about supect problems pxd it as i know you cant just adjust software as the sytem is a reciculation one employing your car parts to burn up gases .How eve rmine allways had low test results and i dont beleive it was dirty in any sense as i am sesitive to doesel gases . I would not have mod done as my car had such low emissions .All the valves egr injection plus etc including exhaust lengths are exactly caculated as a closed system with many preset sensors so would require major redesign if you drasticly alter firing cycles . Current 4x4 has 2 dozen sesors in system and clean , just requires top fuel and ocassinal additve to aid burn of soot , well under limit pass. The goverment must shoulder some of blame along with vosa . I believe most polution was caused by munitions in recent wars along with all the very old buses and hgv trucks tractors on red diesel , not to mentio the Tons of heay diesel used by planes and ships . Motorists must protest as we are no longer easy targets !! We pay huge taxes for little return , clean up public transport and provide more of it because we have paid for it !

Mike7777    on 6 February 2017

If you haven't yet taken your car in for the emissions fix, do not do it. There's nothing wrong with it now and you don't have to have it done. If you do there is a very strong likelihood that you will have problems or reduced performance and you will not be believed that there is a link, and you'll be on your own. Mega stress and expense will quickly follow.

Dan52    on 7 February 2017

I had my Audi A4 2.0TDI 2009 recalled on the 03/01/2017 3 days later i had an engine management light appear on my dashboard, now my car is serviced regularly and hasn't cause me any issues from owning it nearly 3 years ago, but since this update my car judders at low revs when cold and my fuel economy has dropped by about 10%.

10000 miles ago I had my Cam Belt and Clutch replaced so I know for definite it is not either of those causing an issue.

I of course called Audi and was told that the software flash wouldn't be causing my issues they have done hundreds of these and no problems have been reported, I have quite a few Fault codes that have been read on my ECU and only one of those fault codes I already knew about.

1 of these fault codes in particular is to much of a coincidence P0472 Exhaust Pressure Sensor A Circuit Low, I have had my car looked at and the DPF is empty, I am being told by a private garage that I would need to replace the sensor or possibly wiring, I didn't have these problems before the software flash.

In view of what I have read on this very helpful website full of a lot of comments by concerned owners of VW and Audi cars I have created a public Facebook Group, I hope you will all join me on there to Shame VW and Audi group into owning up to there shameful treatment of all of there customers, It is certainly making me think twice about owning another Audi.

I have recently started a public Facebook group to highlight and provide information to others so they can use other peoples experiences to clearly demonstrate to VW, Audi Group that what the dealers are telling their customers are complete lies.

I haven't posted a link to my Facebook group just incase it breaks and rules on this site.

Roy Thompson    on 7 February 2017

The concerning thing here is that there seems to be a "divide and conquer" approach being taken toward customers, essentially stone-walling anyone who raises issues and not accepting any responsibility.

What we really need is a sufficiently loud voice that will make VW take notice, someone like John or Martin Lewis who they can't ignore - does any have any contacts that can trigger any action?

ChallengerII    on 7 February 2017

My gosh, now I'm having problems and looking round for an answer i wish i too had read this thread before taking my cars in for the emissions 'fix' a couple of weeks ago. Both our 1.6 Tdi cars - a Golf and a Touran both built in 2011 - have had the problems experienced and being reported here.

My Golf runs on after i have stopped and removed the keys from the ignition with a slight judder being sent through to the steering wheel. Feels like the engine is still running! Very alarming to say the least. It did it last night after a quick 2 mile trip and again this morning after a 4 mile trip. Had the cars for years and never encountered this before.

Neither had i had any problems with a 'dead spot' in low revs changing up or down gears whereas now there can be a definite lag - just when you are demanding more power - it could be dangerous if you cant accelerate and get the response you need when you want it!

This is on top of having had to shell out over £550 for a new EGR valve on our bought new five year old 49,500 mile 1.6 tdi Se bluemotion Touran. Shocking and according to my garage a common failure on such vehicles.

Beginning to regret getting the VW emissions fix done and wondering if it can be reset back.

Challengerli - you need to check your oil urgently. It sounds as if your oil is overliffed with excess fuel from interupted DPF regenerations. If the level is high get an oil change right awy.

SAME EMISSIONS PROBLEMS AFTER UPDATE
My Audi Q5 2012 2.0 went in for it's emissions update last Friday 3rd and after 200 miles is now undrivable. The power disappeared on acceleration and smoke coming from the exhaust in gears 2-4 and strange noises from the engine. I too wish I'd seen this thread before taking it in. It is due to go in tomorrow for it's diagnostics. This is no coincidence and Audi needs to sort this out everyone is ending up with £1600 bills to sort out their mess. I am going to take it to my local press in Coventry.

The Engine still sounds very throaty and clanky in low gear at high revs. I drove it into work yesterday and today, but on the way home tonight the engine cut out at a roundabout and wouldn't restart. I called the AA, but after a few minutes it restarted and I drove home. Just waiting for the EGR valve to go again.

My Audi A3 went in for update in Leicester Jan 6th. 13th Feb on motorway light appears on dash for engine management system, loss of acceleration later another light emission control system. Have returned to Audi today who say it is unlikely to be related to update....had to sign to agree to pay for transmission test for them to investigate.
Have only heard about this site via a friend and deeply regret update as I am dreading what is now ahead!
More to the point is anybody taking this further? This should be made more public.

Hey HonestJohn.co.uk can you lead us in this one? It sounds like there are a lot of problems out there and dealers perhaps not being as honest as they should. I was told only this morning by dealer that it wasn't a problem they had come across much!

Took my Seat Altea 1.6 ecomotive 63 plate to have the update done 2 weeks. Only had the car since October, didn't think anything about it when I got the letter stating to come in for the update, wish I had done some digging beforehand now. I do the same Journey all on main A Roads and dual carriageway to work each day at stupid o'clock each morning so there's minimal traffic which means I sit with cruise control on for 3 quarters of the journey. Before the update was easily getting 56 to 57mpg on this trip, since the update can't get over 46.1 mpg and the engine is a lot more noisy when idling in traffic. Really would like to know if this can be reversed, Don't want to go back to Seat as it looks like from the above post's nothing gets done! Presently i'm left with a car that has become economically unviable for me. If this can't be reversed may as well just sell it and cut my losses.

VW Tiguan Match TDI 4motion 2011
I loved my car, smooth running, great mpg and very responsive. Software update Jan 2017 and all that changed - immediate difference in power, mpg and revs. Also the clutch bite seemed higher. 3 weeks later as I was parking the car it lunged forward and stalled. The clutch pedal fell to the floor and the gearbox is stuck in gear and it refuses to start. There were no warning lights on the dash. Has anyone else had this problem? Could it be related to the upgrade?

Had the EA189 software upgrade on a 110,000 mile VW golf 2.0 TDI 2011 DSG last October. Within a couple of days had problems with lack of power and engine mis-firing particularly at low revs - 1500 - 2200.

VW dealership who did the upgrade then took the car back for 4 weeks liaising with VW in Germany. In the end they had to replace the EGR valve and all four fuel injectors. There were also problems with the engine temperature. Oil temp reached max 70 C while water temp fluctuated wildly.

Dealership had to challenge VW hard as they denied the engine temp problems had anything to do with the software upgrade though the problems occurred immediately after the software upgrade.

Early Dec car returned and ran OK for two months though with lower fuel economy. Last week, same problem re-occurred with lack of power and engine mis-firing. Most noticeable on a cold start though even after reaching running temp reduced power and mis-firing.

Took back to dealership who investigated the problem. They are now having to replace all four fuel injectors AGAIN and the fuel pump - agreed by VW. Apparently the software resets the engine to behave as if it is new and older engines cannot cope.

There is clearly a significant and known problem with the software upgrade particularly it would appear on higher mileage cars.

I loved my golf before the upgrade - but since then it has NOT been good. VW are clearly now aware of some big problems since they are advising the VW dealership on what is required.

Not sure what is now going to happen when I get my golf back - will it need new fuel injectors every other month?

2011 Passat Bluemotion 1.6.
Was running perfectly before update.
In for service, MOT and recall update today (after being reassured that it would have NO detrimental effects).
As soon as I put foot on accelerator to pull out of dealership, I could hear whirring noise when revs were above 2000. Never heard it before. Kicks in all the time above 2000 revs.
Straight back in to dealership 10 mins later. Technician confirms presence of strange noise, which they've "never had before after an update".
Now they're contacting VW to to a "disreport" and see what they advise.

The first software defeat device loaded into the ECU was known as the "Akoustik Function" it was designed to solve unwanted "diesel combustion knock". The device injected extra fuel which silenced the knock but messed up the emissions results in the lab rolling road test. Audi then developed the "Akoustik" code to detect the dyno test when the function was disabled, but re-enabled for on- road normal driving.

Perhaps the new software code has deleted the "Akoustik" code which may explain the complaints about engine noise.
