I hate this damn DPF

[Rod_H]

We prolly have a problem with these cars because our speed limits are so low.
These cars should be zooming around Autobahns at 160+ k's. Not tootleing around at 40kph because we mite kill someone if we go over the magic number set by the government..

[Spoddy]

but for now my face is to have my dub back

So how happy are you? IS the car behaving as it should???

so far so good! im so attached to that car lol. think yourself lucky for not having a dpf.

funny thing is it did 600km's of fast driving not long before it shat itself, i would have thought that would have been ample time for it to clear itself still hoping it was just my dpf that was faulty

sorry to bore you with this crap but the good ol' diesel particulate peice of **** warning light is on again... *sigh*

Bugger ! Maybe it wasn't a faulty filter after all.

CAUTION: The following is uninformed speculative technical material by a non-mechanic, and should not be relied upon in any way, shape or form:

Next suspect would be the controlling electronics. AFAIK the ECU/s monitor the flow resistance in the DPF to detect a build up of soot particles, then add in extra fuel to the combustion process to heat up the DPF to get it hot enough to burn of the soot. That is why it tells you to drive above certain revs for x minutes (it can't produce the extra heat at low engine revs).

Other possibilities are:

Faulty sensor/s (ie the DPF isn't actually blocking up, but the sensors think it is)

Faulty programming (possibly threshold level set too low, causing DPF problems to be reported when there aren't any)

Partial blockage further down the exhaust raisng backpressure (but I thought the sensors were supposed to measure pressure differential across the DPF).


Whatever, I hope they find and fix the problem quickly, not muck about for months when they don't really know the cause.

Not boring us at all.
I was waiting for your head to pop up again even though i was hoping it wouldnt considering what I'm getting in March.

I do hope this is just a problem with someting on your vehicle and not going to be a common thing.

Does anyone know if the DPF can be removed and the ecu programmed to not light up the warning light?
Surely the DPF would create alot of exhaust restriction and with it removed we would get more power and faster spool up of the turbo too maybe.??

it can be no doubt. in fact i would much prefer to not have the dpf and one day i will certainly take it out and fit a custom exhaust. the only thing stopping me from suggesting they pay for such an exhaust is that i dont want them to do that until they know whats actually causing the problem. i mean if theres another part thats faulty i want that fixed first. but sure if its a design problem (which i doubt it is) just cut the thing out and weld a piece of pipe in instead.

i was just thinking, yours might not have quite the problem since you have the dsg; if you're lucky it will adjust its shifts accordingly to keep the soot at bay.

My DPF light hasn't come on either after the first time and I've got a manual.

I agree that its bad design though. Its hard to keep it within the 1750-2500 mark when your plowing through 50 zone after 50 zone in Sydney. The engine doesn't sound right in third at 2000rpm...sounds much happier in fourth but then the revs drop to around 1500rpm.

Anyway hope it gets sorted mate. I'm sure all the GT Sport TDI owners are watching this thread with bated breath...

[briseos]

just discovered this long thread and read through all your problems.... I

currently have an Eos TDi and sold my 21/2 yr old 60,000k 2005 Golf 2.0TDi to buy the Eos. Both cars do around 25-30k/yr with at least 60% of that in Brisbane traffic... slow because roads are unbelievably poorly designed (traffic lights on a roundabout????).... the average speed over the last 2000kms in the Eos (No 13,500km) was 18km/h at 7.1 l/100km.... and the Golf was driven the same way. They both get a highway run around 4-5 times /year of which one is >4500km return trip avg>100km/h..... yet I have NEVER seen any sign of the DPF light and both engines have the DPF fitted.

AND the Punto does not blow any smoke but certainly goes like stink... 98kw/280nM... but lighter and manual yet >6l/100km town and country! - unaware whether it has a DPF but certainly has bigger/heavier flywheel!

The Eos engine is a hell of a lot smoother and quieter than the golf was and is just loosening up nicely now, but it NEVER blows any smoke whereas the Golf used to let it rip if your floored it.... and the Golf used oil (needed to change around 7500km each time) whereas the Eos' oil remains pristine at 13500km... ??

SO is what you guys are experiencing related to the 125kw engine (I WANT THAT ENGINE in the EOS!)... or is it because I have the DSG and rarely rev the engine >3500rpm (because there is no point - just change gear and hold on!)...

[Mischa]

me n' the german are the same person just this is my new account

briseos - dont mean to offend but neither the 103kw golf nor the eos tdi have dpf's fitted. spoddy had been told by his dealer (on more than one occasion, even confirmed it when he specifically rang up to check) that his car (regular 2.0 tdi) had a dpf when in fact it doesnt. one of the selling points of the new 125tdi is that it has the dpf however let me tell you thats not a good thing lol. if you have your car up on a hoist you will find that it doesnt have one.. lucky you

glad to hear your eos isnt drinking oil, maybe you drove it harder when it was young and the rings were sealed better. i reckon the eos is the only convertible you can sit in without feeling like a chick. oh and that punto sounds like a blast too

EDIT: SORRY! i am wrong. the eos does have a dpf. there must be something else dodgy about my car but i cant face giving it away again its been in the garage half the time ive owned it.

Wheres those "lemon" laws that we so much need.?????

interesting....

do i remember wrongly about your fuel economy being less than optimal... and the dpf is clogging up... but how does it GO? compared with another maybe?

one would hope that the mechanical side of things is right - so maybe a problem lies with the engine management... who knows i spose...

i wonder if an oettinger chip would actually FIX your problem?

I seem to remember a thread from some time ago with someones toe-rag diesel. they were having some issues and it ended up being fixed by the VAG service guys re-flashing the stock ECU because it was erraneous or something like that...

Hi All,
Sorry to resurrect this thread. I want to know what happened to the OPs car?? I too is experiencing same problem on my MY12.5 TDI passat picked up early march 2012.
