I have a 2005 Audi A6 and recently while driving the car the parking break goes off but doesn't seem to change the speed of the car. I turn the car off and on and it is back to normal.
It seems to happen after I have been driving the car for over 20 minutes at
one time. Do you think it might be a sensor issue or a serious problem.
Scan it for DTC codes before doing anything see if there other codes .. Not just the indicator icon for parking brake.
