Shop which repaired car tried to find a used computer out of 3 other audis 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 audis 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. …”
NHTSA complaint #10149026, filed 2006-01, 103,000 miles“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. …”

NHTSA complaint #10469694, filed 2012-08, 127,000 miles“Audi claims that transmission fluid and filter never needs to be changed, this is not only incorrect, but this also causes transmission problems on a regular basis. This should not be told to the customer for it is a lie just so the customer has constant transmission problems while Audi racks in the money. It is a scam and it should be eliminated from potential and existing Audi customers. No oil was ever made not to break down and not ever be changed. …”
