I driving through my neighborhood when I got a flashing light on my dash, quickly the engine began to feel shaky and the vehicle shut off completely. I was able to pull to the side of the street but the car would no longer start. The car had to be towed to the closest vw dealership. The next day I received a call from the dealership telling me it was a high pressure fuel pump failure (hpfp) that caused the issue and that because a part had to be ordered and the work required was extensive, it would take them about a week. I did get my car in about 5 days and all repairs were covered under warranty. I asked the service manager how much the job would have cost without warranty and he said it was about a $5,700 job! it appalled me that he had no explanation for why the hpfp failed so early into the car's life. Needless to say, there is a sense of uneasiness that I have now wondering if this could happen again when the vehicle is no longer under warranty.
