Dear John,

I have a VW Passatt TDI 130 bhp (or used to!)

At just over 100,000 miles there was loss of power which was caused by turbo failure.
This was rectified by the local VW dealer (turbo boost valve) who was not prepared to offer a sympathetic warranty despite it being only 4000 miles over the warranty. I have had no problems with the engine until this time.

At motorway speeds the engine seemed lumpy and the fuel consumption reduced to 35 mpg, about 12 mpg what it usually is. I mentioned it to the garage who suggested I book it back in but because it was driveable they wouldn't be able to look at it for at least two weeks.

After a couple of weeks it failed again with exactly the same symptoms.

I took it in again and something else was replaced on the turbo - the mass air flow sensor. According to other sources this can fail at mileage above 90,000 miles however is not something that is checked during any service.

Six weeks later the turbo exploded when I was driving at high speed in the outside lane of the motorway. There was a loud clanking sound and grey and black smoke everywhere so much so I couldn't see where i was going!

The VW dealer said that the problem was unrelated to their previous work on the car and that a bolt on the turbo had worked loose, got into the engine which and then all the oil was sucked out over the bonnet and onto windscreen. When I asked why they said that 'this usually happens'.

If it usually happens why is not reported as a design fault and checked during services? I queried this and they had no answer but to tell me that a new engine would cost £6000 to fit.

As the dealer was involved with fixing the turbo in the first place and also mentioned that the bolt working loose is a common fault then why was it not checked during the time it was in the garage and also during the service in between these times?

Please can you advise what I should do as I believe the garage or VW to be partly responsible for this known issue.

Age of car?
Regular VW service history: as recommended and stamped?

Hi. April 2003 registered. Full approved VW service history as they can use independents now. The car is owned by my company but we use a lease type fleet company to manage the maintenance and repairs so all the services including tyre changes and gearknob change is documented.

Are you sure that the firm who serviced the car used the correct oil, ie. 505.01 or 506.01?

In my experience most garages haven't a clue, or even care which oil they use.
Passat Turbo Exploded - chasman
not a clue what oil they used. nowadays they just stamp the book - if they can be bothered. they gave me no paperwork like 5 years ago it would be a checklist on what they did. i can always ask but they will probably tell me they used the proper stuff even if they didn't. As a note, when i went to pick up the car the second time they had knocked the tax disc down into the dash and also seized the handbrake on. they had also discoonected the battery without resetting the code so not only did the radio not work, my phone set didn't either. another hour of wasted time waiting for them to fix it.
Passat Turbo Exploded - Altea Ego
The MAF and the boost valve are not actually on the turbo, so its perfectly feasible that complete turbo failure is unrelated the work previously carried out.
Passat Turbo Exploded - chasman
yeah. I know. the fact is that they didn't replace the mass air flow sensor and the turbo boost valve at the same time as both had actually failed. this shows poor knowledge and service. the maf often doesn't show up on the diagnostics i am told.

then they mentioned that the cause of the turbo failure was the bolt coming undone - this is a known problem to them but is not checked in any service or as part of a turbo issue. a design fault?

It seems a bit rich for the service guy to say - 'that's what usually happens' and then present a quotation for £6000.
Passat Turbo Exploded - bikemade3
If only everything in life was as reliable as a **.

Good to see your service guy passed VW's servicing school final exams with honours.
Passat Turbo Exploded - chasman
want a summary of what has happened to it over the last two years?

gear shift indicator fell off after 35 miles. the vw garage glued it back on but to do this they had to scrape the paint off the back of the cap so it looked worse than without one. i puuled it off and was left with a nice chrome / ally top to the gearknob.

the foot rest next to the clutch came unattached and got in the way of gear changing. this was fixed but only after some frank discussions with the garage - they tried to make out it was wear and tear.

someone knocked the drivers wing mirror off so i had to get areplacement fitted. they buy them in plain and paint them. they painted it the wrong blue. again, frank discussions about this. they said they had used the correct colour code according to the car's registration. it was plainly obvious it was the wrong colour so i sent them back with the car to fix it.

the paint is now wearing off the mirror only 1 year later.

the main issue though is the £6000 they want for a new engine. I have wriiten to the sunday times and watchdog.

I have also suggested that everyone who owns a passat tdi get the turbo bolts checked.

Have you written to VW UK head office. I suggest you do that pronto. Regards Peter

Yeah - 3 years or x miles, whichever comes first isn't it? Check out his mileage Adski. Astronomic or what!
Passat Turbo Exploded - chasman
Hi. Yeah. Gonna write to VW UK. I have spoken to them but writing is the best option.

I do alot of miles - in the foam selling business so could be in Cz one day, Northern Ireland the next etc. Not a patch on our divisional director whod does nearly 3k per week!
Passat Turbo Exploded - chasman
forgot to say that the warranty is 100,000 miles or three years whichever soonest.

The car went wrong at 104,000 and still VW would not give me a sympathetic warranty, just a pathetic warranty!

Service and Maintenance

We offer our customers a lot more than just a reliable car.

That is the quote from their website.

Add the appropriate line and I'll quote that in my letter.

I thought of, more than just a reliable car, get to know your service team on first name terms as well.


Passat Turbo Exploded - Dr Rubber
Chasman,
you might want to check the warrenty information. VW cars in the UK for the last few years have had a two year unlimited milage meanufacturers warrenty, with the third year (60000 mile max) dealer extension if you service the car at VW. Based on this your car is well out.

Out of interest, what exactly failed? External bolts that are easliy checked are not likely to go down the inlet tract.

Good luck with VW anyway, I'd be rather annoyed if it happened to me after 2.5 years!

Joe
Passat Turbo Exploded - chasman
Hi Dr. Yup. Checked and it is 100,000 miles or two years from the factory.
Passat Turbo Exploded - madf
I suggest you get a sample of your engine oil removed - under witness- and ask VW to analyse half,, keeping the balance as evidence.

If the only things that actually went wrong with the Passat in 100k were a loose gear knob top and a loose footrest I'd say that was wonderful reliability.

The subsequent wrecked engine is very bad news indeed.

I am interested/nervous as my out of warranty ,December 2001, Passat turbo diesel 100ps will hit 100k in the next 18 months at the present rate.

I wasna fu but just had plenty.
Passat Turbo Exploded - adverse camber
I would like to know what actually went wrong. What bolt ? How did it get in the engine ?

From your comments it sounds like it was not serviced by the vw dealer. They replaced the boost valve and the maf, both known to fail at high miles. You dont say that it wasnt running ok after that so I assume it was. MAF failure doesnt always show up on diagnostics. depends how bad it is.

the turbo then failed.

Are you sure the engine didnt fail due to oil loss ? What bolt from where ?

6k is probably the cost of a new engine and fitment. Its easy to get a 2nd hand engine and get it fitted at a fraction of the cost.
Passat Turbo Exploded - chasman
I have spoken to the garage who can provide a report of the damage but because the lease company has decided not to pay for it they are unable to do it.

they have just told me just now that i should refrain from long journeys and when i come to a stand still should leave the engine running for 30 seconds to allow the oil to cool the turbo.
no-one ever told me this?!

they said that turbos can blow and that there is nothing they can do.

they have said they don't know if it is a bolt that came off.
Passat Turbo Exploded - boab67
The nut/bolt that they are on about is probably the securing nut/bolt that holds the turbo impellor to the turbine/bearing shaft.What might have happened is that the shaft became worn due to age/amount of vehicle milage thus potentially causing a vibration thru the turbo shaft which may have caused the nut to run slack and end up entering the inlet manifold,hence all sorts of mangled damage.
Passat Turbo Exploded - pmh
If a whole nut went into the inlet manifold surely it would not get past an inlet valve? At worst, it would jam the inlet valve open, or am I missing something? I suppose that this could then result in piston - valve contact destroying one piston and possibly one conrod. Would it suffer any other damage. That would then account for some oil smoke.

Surely the most likekly cause of smoke is oil from the turbo feed in contact with the hot exhaust, particularly if the turbo housing destroyed itself. So why the terminal engine damage?

Does this version have an intercooler? I am am not conversant with vw design, but but several other makes would not let a whole bolt thro.

I think that there are still a lot of questions to be asked here about the actual failure and what has been destroyed.

'they have just told me just now that i should refrain from long journeys and when i come to a stand still should leave the engine running for 30 seconds to allow the oil to cool the turbo.

I dont understand this. If the engine is dead why are they saying avoid long journeys ?
It is common knowldge that you let turbos cool. and has been in the handbook of every turbo that I have owned (and that includes several vag cars)

You are not giving a clear picture of what happened, or why. But you have had a good whinge. You never had it serviced by vw and complain when they dont auto extend your warranty.

Hey Ho.
Passat Turbo Exploded - wonderwheels
Sorry to hear about your car.It is "hit or miss" whether someone buys a good car or a bad one these days irrespective of the manufacturer.I had a 2001 TDi (130) and had nothing but problems with it.Most under Warranty but it put me off buying one again.Servicing is expensive and the Dealership were only interested in making money not Public Relations.If there is such a thing as "this is a common fault" then you would expect a Dealer to check for this.If that is what has happened here,definitely get on to VW Customer Service because they will be aware of this,the only thing that might go against you is that they are quite specific about mileages.I had a variety of faults with my car,the last of which was a window regulator going (a common fault).I was quoted around £160 to get this fixed but after speaking to customer service they paid 1/2 the costs as it was a common and known fault.I appreciate that your repair is on a different league and regardless,I think you are going to be out of pocket a bit.The whole engine thing with the PD seems a bit hazy and if it is not treated with respect can prove very costly.Having to use the specific oil is a perfect example.Unless a main dealer is used,I would be very careful that the correct oil grade is going in.Good Luck =o)
Passat Turbo Exploded - Robble
You don't need to wait for engine to cool down on a turbo diesel before you turn it off because the exhaust gas temperature is a lot lower than on petrol cars and will not cause the oil sitting in the turbo to carbonise. I think the only exception to this is when you have really been thrashing it hard down the motorway and then suddenly stop and switch off, but how often does anyone do that?
Passat Turbo Exploded - chasman
Just heard back from the garage and the company who manages the fleet.

The car will be scrapped as it has been valued by VW at less than £900.

I have had no reply from VW. The garage has denied all knowledge of saying that it was a known problem.

The fleet company has no guts to challenge VW or its service agents and are not prepared to investigate unless they are paid to do it upfront!

The fleet company are deleted - no naming/shaming thankyou. DD - suggest everyone stays well clear. Also VW - well what do you say?

My fleet manager suggested I opt out of the company car scheme as I now have the chance to do so needing a new car. After this expereince I can say it is probably better sticking with the company car policy as then I wouldn't have to bother with all the costs associated with rubbish servicing.

Espada III - well if you have a family and need a Lamborghini, what else do you drive?
Passat Turbo Exploded - chasman
Why have you put no naming and shaming. {See below. DD}

I have yold you about VW? The fleet company are just enough to blame for the bad service. They were going to take it to a different garage each time i had a problem caused by a previous garage. not common sense. they just have no guts to interrogate VW.
They even rang me the other day to ask what day i had returned my hire car. i told them that i was actually still using it as the car i had was according to the previous person who called me from there, going to be scrapped.

where do i complain about these guys then if i am not allowed to mention their name?

my company is now paying £25 per day for a laguna that does 30 mpg. it is costing us a fortrune compared to the VW as that did 47 mpg. i do over 500 miles per week sometimes nearly 1000 and so it all adds up. again, if the turbo had blown up 10,000 miles before then this would all be on VW but it isn't so i shall stop moaning have some tea and then go out and conned by another car manufacturer.

oh and by the way, thanks for all your readers help suggesting things like writing to VW - well, i hadnt thought of that.......

trying to get an oil sample from the dealer - who do you think i am - Columbo?

ford reliable? the governor / speed limiter tends to slip so they keep slowing down and need retuning.

honda? rover in disguise.

etc etc

U what? I can inderstand you being a tad annoyed that a car "only" managed 100,000 miles before something major went wrong, but to start taking drugs and spouting rubbish is a bit of an overreaction.

Passat Turbo Exploded - JohnM{P}
'The car will be scrapped as it has been valued by VW at less than £900.'
Who exactly has valued it at less than £900? A VW Dealer? £900 presumably is the value of the car minus cost of a new engine. As Mark99 said, the cost of getting and fitting a second hand engine (especially at an independant garage) will be a lot less than £6000.
Someone will buy the car and do just that and make a few bob...
Passat Turbo Exploded - chasman
like i said the fleet company and the VW dealer have a lot to answer for. i have had no reply from VW so it just goes to show that cars are in fact the biggest money pit ever.

the quote from an independent was £3.5k. if you think it is such a bad price then can you do
better?

better than (Deleted again. Any more and you're out of here. DD)

You get a lot of useless unhelpful rubbish on these sites - thanks for pointing that out. do people have no work to do - guess posting useless comments on forums (forII) beats solitaire.

Have you tried writing to VW customer services chasman?
Passat Turbo Exploded - chasman
no reply. i emailed them and as usual they are very efficeint and responding with all the customer care crap and then you hear nothing. i am still waiting. tried calling them but was on hold for 30 minutes and some robot kept telling me to visit their website and that i was an important customer so keep holding. it is an 0800 number so that means it's ok to hold on forever?
Passat Turbo Exploded - chasman
great. the first correct thing said on this post but unfortunately doesn't get the car back.

anyway, just haven't got the time. need to go an fill up the laguna. this is now part of my daily schedule and i have lerant how to do it easily. the laguna has an automatic handbrake! it has automatic lights! it has cruise control! the stereo is still poor quality though. i took the speakers out and weighed them and they are still as light and placcy as the previous models. I complained about the previous laguna i had in 1998 to renault uk and they refunded the cost of the speakers (£150)even tough it was a company car. that is good. but, can they design a car that does more than 30 mpg? yes the diesel does 40!

how about a passat engine but with a diffrent turbo and the gadgets of a laguna?
