Give this a try:

1. Remove negative lead from the battery for about 20 min. and replace
2. Turn ignition to to first position and leave on for 5 mins, turn to off
3. Start the car and let idle for 5 mins, turn it off
4. Restart the car and go for a drive, that should do it.

I hope this is helpful to you!

YOU CAN FOLLOW THESE INSTRUCTIONS:

Press the gas pedal to the floor.
Turn on ignition but do not start the engine. If your car has Start/Stop press the gas pedal but not press the brake pedal. Only press the START button.
Keep the gas pedal pressed for at least 15 seconds.
Turn off the ignition. Release the gas pedal. Wait a couple of minutes and restart the engine.
Drive your Audi, carefully and allow it to change gears at low RPM for the first 10 minutes.

If the method above does not work on your Audi, the only way to reset the transmission would be with a diagnostic scanner.
