Audi A2 diesel turbo problems

[RonA]

My daughter bought a diesel A2 with less than 15k on the clock. When the car had done less than 22K on the clock the turbo failed. Having been purchased from a main Audi dealer the car was returned & the turbo returned replaced under warranty. Now with 30k on the clock (1 month out of warranty) the turbo has failed again but the dealer has washed their hands of the problem & subsequently it was determined that although the turbo was replaced, the engine oil & oil filter were not. Talks with Audi customer services ongoing.
Having lost faith in the main dealer the car was taken to a independent but Audi trained technician. On deep inspection of the engine the oil filter is heavily contaminated with carbon (something the independent has never seen in car with less than 60k on the clock) & suspects the engine may never have had a either oil or filter change. The independent garage technician even after replacing both oil & filter is reluctant to start the engine in case the carbon contamination blocks off the turbo oil supply again triggering another turbo failure.
Anybody had similar problems & how did they get round them. So far this exercise has cost approx £1300 but without a final solution in sight.

I think Ford have the same problems with one of their diesel engines in that sludge is forced somhow into the oil supply killing the turbo.
Idiot main dealers do the minimum work to return the car to the road and often don't do things like an oil change after a turbo failure! STUPID
About the dpf filter, if it's a car less than about 7 years old it'll have one and if it's not had a regen for a long time it fowls up everything.
My wife's Zafira, the boy's call it a Crapira! had a similar problem that has filled the intake manifold with crap, this was eventually traced to a tiny split in a vacuum hose that supplied the turbo wastegate solenoid. It stopped the turbo from coming in at lower revs and dpf regen and knackered the egr valve as well.
Modern diesel engines don't seem to be able to keep up with the emissions regs that keep coming in and the punter suffers.

I've seen photos of audi engines choked solid with carbon sludge
Doesn't have a DPF does it? could be many many failed regens contaminating the oil also with diesel and killing the turbo through poor lubrication...

I think in line with most modern diesels it has the dreaded dpf filter but how many regens will have occurred in car which has done less than 30K? I forgot to add the technician had interrogated the cars cpu just in case the car had done more than the indicated 30k & had been "clocked", unfortunately the laptop couldn't tell him either way.

When the turbo was fitted they should have done an oil and filter change, if that can be proved that they didnt, then you should be on to audi uk themselves to complain bitterly, the supply pipe should have been, if not replaced, cleaned out, I run apiece of brake cable with the end frayed out in a cordless drill, to clean out the carbon THIS IS STANDARD PRACTICE for turbo replacement also the engine should be run and the oil changed again, shortly after,
in my eyes the original repairers should be taken to task over this.
Picture evidence should have been recorded, by your indy though to prove case and presented to audi uk.
When I take picture evidence I usually put in shot a daily paper that proves the date

Unfortunately modern diesel cars are being sold as an everyday driver they are NOT, if they have dpf's etc they need to be doing 60 -70 mph on a daily basis BUT NEED TO BE DOING THIS FOR SEVERAL MILES if they do the usual taking kids to school shopping etc they will clog.
I have a customer that bought a nissan 4x4 and does 8-10miles to work on a dual carriageway THAT IS NOT ENOUGH, it takes probably 4-5 miles in the summer for the whole engine to get to temp and in winter the whole trip,
they have had several costly repairs to the dpf in the few years they have had it.
A modern diesel is now only for doing 50+ miles in one trip at decent speeds IMO

Yes I am well aware of all those facts thank you but that all those points and reinforces my fact that the average family car should now NOT be a diesel, it is false economy, BUT sales men are still pushing them, and this should be noted to the uninitiated. I tell all my customers that have a diesel as their family car, and have been made up with their diesels that when they replace now to buy petrol.

NO offence taken at all !! I totally agree but the average person and this is not sexist but mainly women only give the car max 1/4 throttle it just isnt enough. The first mile should be done steady to let the engine equalize temp, then it should be, shall we say used fully, even in bursts to help clear the ports etc
My wife had a passat non dpf, that she used to take to work ( she is not a slow driver BTW) and we were for ever having carbon'ed turbo vane probs, Now I drive it no such probs. So its not just DPF's that suffer.
She has since got a petrol no problem at all.
And all this crap about 20,000 mile services only makes things worse and then they state unless arduous conditions,! arduous conditions are commuting short distances going to work!!, doing 70/80 on the motorway is nothing and does the least damage !!
for me 5/6000 is right for oil changes.

 

[normspanners]

yes the low ash oil helps prevents the clogging but the cost !

A free reving engine is a happy engine IMO, like the honda s2000 they are very happy at 9500 and so am I.

The audi spec for the a2 oil change is around 24 -30 K!!! IIRC which is absolutely crazy that can be 3yrs !!
No wonder they have problems the oil must be like tar.

I'll get my daughter to question that in her discussions with Audi customer services.
