    Hi guys really need someone who knows 2.0TDI BKD engine inside out. Had my 2.0 TDI S line quattro since new in Dec 2005 first 22000 miles all was well until Turbo started whining like I was being followed permanently by a police car.This was replaced under warranty. All well again until new turbo failed with overboost issues (vaines sticking) having only done 14700 miles car was just out of warranty but due to length of time turbo had been fitted Audi fitted another turbo as a good will gesture. This is where I need help 3rd Turbo failed again with overboost issues (sticking vaines again) having done 11600 miles. Audi say the turbo's failed due to too much soot causing veins to stick exactly same fault as previous turbo, surely there is some underlying problem causing this anyway Audi fitted another turbo free gratis as they say it shouldn't have failed in that mileage! New turbo was fitted and Audi had the car a week to ensure there was no underlying issue causing the turbo's to keep failing. They couldnt find anything at all and I got my car back again, this was last Wednesday I had the car back 1 day and the new turbo failed again whining its head off. Car went back in on Tuesday this week for its 5th turbo fitting. got my car back now but have a problem with smoke when starting the car. When I first start the car for first few seconds car doesnt want to idle properly then it clears and idles normally but then I get grey smoke bellowing from exhaust till it clears. I returned car back to Audi to see if they could resolve starting/smoking issue, only to be told they don't know whats wrong with it. If anyone has got any ideas or could explain what could be causing turbos to keep failing or the starting smoking issues please respond. The car has done 47780 miles always been serviced by Audi dealer and run on Shell diesel.

    Its obvious getting far to much **** out the back end that also gets into the exhaust side of the turbo to clog the vanes, this should be there 1st check to see why its chucking out so much **** to make turbo's fail & to make a new turbo fail so quickly it must be chucking out some serious amount of ****, sounds like a combustion issue to me.

    Are they fitting brand new turbo's or recon's?

    Hows your economy?

    Hi NHN thanks for the reply. The turbos are remanufactured according to the dealership, economy is getting worse and the issue with the starting/ idling has only started since the turbo has been fitted. The dealers asked me if I drove the car very steadily as they said it smoked a lot under hard acceloration. It does this all the time. They have said that they have checked everything with the diagnostics and everything falls within the parameters set by Audi. I also get what seems like a misfire but this is intermitent. Looking through the threads on here, the problem I'm having seems related to the MAF sensor. I've been back intouch with Audi UK customer services this morning as I'm not a happy chap at present! The dealership in question just don't want to know, which annoys me as the starting issue wasn't present until they fitted the last two turbo's. The top and bottom of it is the equipment that the dealers are supplied with by Audi isn't sophisticated enough, and not once has the car been tested under load, only whilst idling within the workshop If the computers dont show a fault there opinion is there isn't one! I've spoken with a specialist near me who was very helpful and agreed there was an underlying problem causing the turbo's to keep failing, but he is unable to look at the car until 5th Oct as he's booked up solid. Audi UK are ringing me back on Monday after speaking with their technical support department to see if they can resolve the issue. I will keep you posted on my progress. Thanks
