Going 55 mile an hour, rear turbo seal goes out, sucks engine oil out of crankcase. I coast to a stop. Load on a trailer. Haul to a Audi dealer. Still under warranty they replace engine. Now they say transmission is not repairable. Now I have to pay for new transmission. Drive train was still under warranty. Never buy another Audi again. Audi has had the car for 2 months still don't have the car back.

This complaint relates to a tdi version of the Audi A3. While driving my kids to school, the car stopped dead and would not restart. On inspection by an Audi dealer it was determined that the high pressure fuel pump had failed. The pump failure caused metal particles from the pump itself to circulate in the fuel system doing catastrophic damage to the fuel system and power train. As of this date, the car has been in the shop for repair longer than two weeks with no estimated date of completion. We experienced a similar catastrophic fuel pump failure with our Audi Q7 tdi in June of 2012 which required a new engine, fuel system and other parts (see ODI # 10480946). According to the dealer, the reason for the delay in repairing the A3 relates to the large number of cars with similar fuel system failures which has caused a scarcity of parts. We have been told by the dealer that this same problem is happening to tdi vehicles from both Volkswagen and Audi. I am no engineer, but widespread fuel system failures seem potentially dangerous to drivers and their passengers. This problem deserves an investigation.

While driving on local roads, engine lost power and stopped running suddenly. I was able to restart the car after a minute or so and continued my trip to work. Car is an automatic and the engine just quit like a manual left in gear at a stop sign...a shudder then nothing. Not sure if relevant, but I could only restart the car after completely turning it off and removing the key.
