While departing a parking lot onto a primary road, the check engine light illuminated and the glow plug light began flashing; the car immediately began losing power. I returned to parking and the car was towed to an Audi dealership where they diagnosed the problem as a failed high pressure fuel pump.

On my way to work my car stalled /lost power, glow plug light went on then I couldn't restart my car. I had to tow my car to my dealer where I bought my car. The next day they called me that they have to order alot of parts and replace entire fuel system: Fuel pump, hpfp, fuel line injectors and seals and they have to clean the tank! I would like to inform you that I am the original owner and only me was using that car. I have never used anything but high quality diesel fuel from shell gas station located on dempster street in skokie, il. I buy ulsd once a month and have all the receipts from this year ( and if necessary from day one from my bank credit card history) because of this I am 100% sure that any claim that I used wrong fuel is without base. If the ultralow sulfur diesel fuel recommended by car manufacturers doesn't much specification this should be resolved before putting diesel car on the market.I would like to mention that all maintenance on my car was done on time at authorized dealerships.I change oil every 4K miles instead 10K as manufacturer recommending my Audi' warranty expires next month and I hope that Audi will extended my warranty for another 4 years/50K miles!!! if not I have to get rid of my car that I was planning to keep for long time. Bad hpfp craftsmanship and design should be corrected as soon as possible if Audi/VW wants to sell diesel cars in us!

Was driving along at highway speeds when glow bulb indicator came on immediately followed by loss of power to accelerator. Was able to get off the highway after about 4 miles and car then experienced complete engine failure and was rolled to the side of the road. Engine would not turn over after two attempts to restart the engine. Car was towed to local service at Audi dealership. Service department from local dealership described the cause of engine failure was due to metal filings found throughout the fuel system caused either by fuel pump failure, or bad batch of diesel fuel.

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.
