Other Fuel System Fuel Injection System Problems of Audi A3

I own an Audi A3 2011, tdi. I had two similar incidents with the fuel injection system with this tdi. The first time it happened when the cars just passed the warranty period of 50,000 miles. I drove this car in city street and the “glow-plug” indicator light came on. I barely made it to the Audi service. They told me that I contaminated with unleaded fuel. I told the service manager that is not the case because I only use one gas station and usually, I used the same diesel pump. After Audi dealer talk to the Audi of America, they decided to pay for the repair, approximately $8,000. Then this is the second similar indecent. I started the engine and hear unusual clanking noise from the engine. I continued to drive the car in city street to my home. Then suddenly the “glow plug” lights momentarily flashes. The engine dies immediate right after. I coast the car to the curb. I took the car into the dealer, and after a day, the service manager again told me that the fuel system was contaminated with unleaded fuel. I assured you that this is not the case because I am the only one who drove this car. The service manager told me that Audi did the analysis and it indicated that the fuel got contaminated, but continued to deny the accusation because I am very careful in using the “ultra-low sulfur diesel” for my car. The first incident I only pour my diesel gas from shell station, but since the first incident had happened, I changed to chevron station. After one week, I called the service manager and ask him for the analysis of the contamination, and he said that he had sent to Audi in germany for report. Then I said I wanted the old injection system back so I can do an independent analysis, he also told me he sent the old parts back to germany for further analysis. I seriously doubted that the Audi dealer service department did any analysis.
