I was parking my car in a driveway on clear and sunny day. As I put the car into reverse, the engine suddenly accelerated. The car then spun around and moved sideways causing me to crash into the garage along the length of the car on passenger side. The garage was heavily damaged as were two other cars in the garage. I was not injured except for mild bruising and stiffness in neck and shoulders. Air bags did not deploy. My car had to be towed away. Three weeks earlier, the RF ACC sensor/module J428 was repaired by the Audi dealership in New London. It was out of alignment due to collision/damage to right front bumper from hit and run driver in a parking lot in June.
