Abs controller module failure - bosch 5. 3 system - 2000 Audi S4.
On or about 11/20/00 I applied brakes while driving down hill. Car accelerated out of control. Brakes would not stop car, which eventually crashed into telephone pole. I injured my left leg. Audi advised me they knew of no "defect" that could cause this accident. On 13/21/01 as I applied brakes to turn into a parking space contiguous to a building the vehicle accelerated. When I both heard to engine racing and the car accelerating I fortunately shifted into neutral and stopped the vehice. My foot was not on the accelerator! I refuse to drive this vehicle. Audi's response is that if the dealer finds a problem Audi will take appropriate action. There is a problem whether Audi finds it or not. I am not risking a fatal accident to establish this fact!.
