Transmission and computer broke while sitting in driveway. Shop which repaired car tried to find a used computer out of 3 other Audi and all were rusty. Mechanic informed me that water seeped behind dashboard and under driver's floorboard, rusting out computer, and ruining transmission. Evidently, all other Audi showed the same water damage in the same area. Computer failed to send a signal to the dashboard that there was a problem. Fortunately, the transmission locked while the car was in park and not while we were on the road. We installed a rebuilt transmission and new computer. I am concerned because I drove a vehicle once when the transmission locked while in the middle of a road, coming to a dead stop. I believe this could be a dangerous situation.

My car was accelerating without the gas pedal being depressed. I was fighting to stop the car with the brake but failed to do so as the car was accelarating at high speeds on a major highway. I had got the car down from 50mph to 15 mph. At this point turned on my hazardous lights and pulled over to the shoulder. At 15 mph I safely shut my car off as I was unable to completely stop. After 30 seconds, I turn my car back on and see that the car is hittig redline of 7000 rpms in park mode. I shut my car down once more and wait another minute. I start the car and the car is back to normal. I am being told by many people in my car's internet forum that this has been happening to many people and it is a faulty throttle pedal. The pedal has a heating element that has failed due to the recent extremly cold weather.
