To all,
I'm sure you have all read my experiences with the Mazda 6 and the DPF lights, oil levels rising etc. I won't bore you with any of the details see the other threads, BUT to bring you all upto date :
1. Picked up the Car after 11 weeks and 4 days. This was after the engine blew up. The car has had a new engine, new catalaytic converter, new clutch (although only 2 years old and 14,000 on the clock) new engine thermostat after the new one was found to be faulty and other bits and pieces. (approx £9k that they want off me!!)
2. When I picked the car up I checked the oil level before driving off the forecourt. The oil level was approximately 10mm over the full mark, which is I believe approximately 0.6 litre.
3. 4 days after picking the car up after only 77 miles (of which 45 miles were motorway) the DPF light came on.
4. 6 days after picking the car up and after only 103 miles the DPF light has started flashing. Therefore according to the handbook needs to go back to the dealership immediately.
HAPPY MOTORING - This car is not fit for purpose !!

UPDATE TO ALL,
Took the car back to the dealership yesterday morning because the DPF light was flashing. After 6 hours I still hadn't heard from them so I called to see what was taking the time? I was told that they had regenerated (or tried to) the DP filter but this wasn't the main problem. They suggested that the engine is over heating, the cooling system is'nt operating correctly??
What do all you technically minded people think whats going wrong?
I feel that I might have had a lucky escape because when the DPF light comes on, according to the handbook, you should give it a good hard long run to burn off DP matter. So if I had done this the engine may have over heated and I would have been back at square 1 again. Nightmare.
Nick.

If it's had a new engine, thermostat & other bits & pieces, do you know which parts they DIDN'T replace? Did they bolt on the old turbo / DPF back on?
The problem may lie in the unreplaced bits. And while the dealer is willing, they obviously don't really know what the problem is. They're not diagnosing, they are just fitting new parts and hoping.
I'd suggest that if they didn't replace the turbo / DPF and associated sensors, they need to do so.

Craig, I assume because I haven't been told about a new turbo/DPF, they have used the existing. Are these items expensive??
Nick.
|
They are expensive, probably £1000 each fitted for turbo and DPF.
Is this a warranty job, or are they trying to stick you for the bill? If the car is still not running properly after a replacement engine, I'd suggest that it's a warranty job, no matter what you're being told ....
|
Quite, sounds like they are trying to save money by not replacing everything.
I can hear them now..."no sir, the turbo is not a part of the [new] engine, but we can fit new for £££".
They're having a laugh.
|
Nick's car probably had a new turbo though. When these go wrong I think it's the turbo that goes first and that then damages the engine.
Mine had its oil change yesterday. The garage had to "reset the DPF" or something like that as well as do the oil/filter change itself. We'll see how it goes. Oil now back at the Full mark.
Nick, I feel really sorry for you on this. Your story was one reason I discussed with the lease company again and they suggested I get an oil change because I am not driving it properly.
My oil level was still less than an inch above full but I kind of backed them into a corner. I wanted them to advise and I'd go with it. And if it was wrong and the engine went then it was their and not my fault.
|
hi if your still under warrenty report to your delership surging at about 50mph
they should fit a modified dipstick (put less oil in so oil level meter in the ecu doesn't register so quickly) and reprogramme the ecu to alter soot calculations let me know if this works.

Update on problem.
My car has been in the Mazda dealership since Sat 20th Dec. After the last series of problems with half the dash board lit up - DPF flashing, TCS on and Engine Management lit, they assured in their wisdom that it was an ecu fault. This was duly ordered and fitted yesterday.
I've just had a call from them to say that while it was working well last night the service manager had taken it home and suffered a power drop this morning at the crucial distance (after approx 25-30 miles). The workshop manager is not happy to release the car so it's still being investigated.
When I quizzed him about the DPF he told me about the modified dipstick but didn't say whether it had been fitted too.
Thankfully this is all under warranty - but I'd really just like the car I bought working as well as it did for the first 10 months I had it. Surely that's not too much to ask - is it???
Will keep you posted.
|
Still can't see why they haven't replaced the DPF sensor. As this is the light that always appears, surely this should have been replaced. It's also a lot cheaper than the ECU!
I'd request a 2nd opinion or removal to another dealer!
|
to tell if you have a modified dip stick mesure the gap betwen the marks
12mm none modified 8mm modified (no way to tell if they have reprogramed though)
i have known the rear down stream pressure sensor to become soot poisened causing simular faults (does not always produce codes as still in operating window)

I have the new style Mazda 6 with the 2.0 diesel engine, and the DPF light came on about three weeks ago. I've taken it on a few long motorway journeys since then, and the light has gone off. Yesterday, however, it suddenly came on but flashing, and then the 'check engine' light came on and I have lost the power in my turbo (apparently because it's on 'limp mode'). I checked the oil levels and while they are above full, they are nowhere near the X mark. It's booked into the local garage tomorrow, but it sounds suspiciously like the start of everyone elses problems on here (presumably with the old model). The car has only done 10,000 miles and I've had it less than 9 months!

FURTHER UPDATE
Well, new ECU fitted and software updated. Cut a long story short, fault still happening. Back to the dealership again! Mazda have apparently recognised there's a problem with the 6 and have been working on it - so I've been told. They received a technical update on Friday 14 Jan. Mazda are supposedly going to a do recall for this updated software package to be installed. All I know is it didn't work for my car! So they've been been talking to the technical dept at Mazda and have 2 other 'things' to try. Can't say I'm overly optimistic! Will let you know how it goes.

I have contacted Watchdog .I have 06 mazda diesel with the same d.p.f. problems we all need to fight together.Maybe then Mazda will admit their is an inherant fault with these cars.Please inform Watchdog!

Nitrox - My 04 plate Mazda 6 is having exactly the same issues with loss of power on hills. Mazda have just quoted me "around £700" to fit a new fuel injector. As I am out of warranty this is my money.
What conclusion did you reach with your car?
Thanks
Andy

Hi Andy,
has your DPF light been flashing? or has it been on.
|
Hi Med. This is the only thing that is different compared to Nitrox's problem. When this occurs in my car no lights on the dash flash, or have been lit. I guess it is possible that the bulb has gone for the warning light and as such I am not aware. Indeed there are no other indications of problems other than the loss of power.
The only symptom that may be useful information is that this exact problem occurred when around a year ago with the car after the cam belt was replaced. It hadn't been fitted correctly and since it was replaced the car has worked fine - until now. This is what makes me concerned that it isn't the fuel injector causing the problem but something else. Interestingly the situation is much worse in very cold weather which led me to think the cam belt might have been slipping.
|
|
hi are you sure the cam belt isnt the problem? (they have been known to jump teeth) is there any codes. Have you had the turbo checked sounds like you need a ecu reprogramme. Might be worth disconnecting the battery to reset the ecu to base setings before spendingall that money

Hi all
I'm new to this forum though in no way new to the Mazda DPF problems.I've added to another thread on this subject on honestjohn too.
I have a Mazda6 2.0 TD 143, 2007, bought in January 2010 as second owner. Full Mazda Service History. Excellent car to drive - I like it more than my 318 I traded it in for.
I had almost identical problems to Nitrox. The car has been in for the engine overrun in Feb 2010 as a Factory Recall remapping and has now been in 3 more times; oil/filter change after DPF light came on flashing with TCS and Check Engine lights - there was no DPF warning before this happened. Then again a week later for a Manual DPF Regen after similar warning light issues (with no prior DPF warnings). The tird time its a new DPF after the lights came on again. I raised a Formal Investigation with Mazda UK. Loses power after about 30 mins driving too.
Checked oil level before any long journey - never moved above Full, so if Regen is happening, it is happening completely with no drain back into the sump.
My local dealer is really helpful but I get the feeling they are left in the dark by Mazda UK. I also get the feeling I am paying for all these repairs while they learn what the problem really is.
Surely if the DPF got to the point it needed replacing, I should have had a DPF warning light before total failure, to tell me to do an auto regen by driving it. (I do about 350 miles a week, mostly motorways with appropriate engine speeds for auto regento happen).
I am not an auto engineer but I can analyse things! Surely all these oil/filter changes, DPF regens etc are only treating the symptoms of a fundamental and inherrent problem in the engine?
I have today written to Mazda UK to see if I can get any response from them. If anyone else has had Mazda acknowledge this problem, and had a satisfactory outcome from Mazda UK, I'd be pleased to hear from you.

Hey,
The same old DPF! I tell you something, Mazda UK when they found about the engine over-run on my brand new 2nd gen mazda they didnt seem to care, and the dealers only go by what Mazda UK say. They all know there is a problem & none of them are persistant in fixing it until they have enough money/support from the government to design something slightly better.
My huge argument with Mazda UK and the dealer still continues, because of this problem i am in the process of getting my engine stripped down to find where the problem is therefor ending in taking mazda to court to finalise what i went through and what everyone else is also going through!
http://www.mazda6forums.co.uk/forum/index.php/topic,435.0.html thats my post & i have a post on here too http://www.honestjohn.co.uk/forum/post/index.htm?f=4&t=77225
I am still in a continued argument with Mazda and have been without my car for 8 months now, it's dead outside, wont start even if the battery is charged and the tyres are now flat! I was only able to drive it 10 months from new until this happened.
Do you all not think the handbook should be changed?? to state what to do if you do not check the oil levels, or ignore the DPF light. If Mazda know about engine over-runs then why is that warning not in there??

Sorry to hear of your problems Med. Sounds like the legal route is a rough one to follow.
I have also written to watchdog at the BBC. The more outlets, the merrier I thought
I am also wondering - given the large numbers of us people that seem to be suffering with ongoing Mazda diesel problems, whether a Class Action would be worth pursuing in court rather than a few of us who are bold enough to go it alone?
Does anyone know just what is needed to start a Class Action?
