How to Reset the Tire Pressure Warning on an Audi A4

1. Park the A4 on a level surface.
2. Fill each tire to the appropriate air pressure. The recommended pressure is printed on the sidewall of each tire. Use a tire pressure gauge to make sure the pressure is correct.
3. Drive the A4 at above 25 miles per hour for approximately 10 to 15 minutes. Once the computer has received enough information from the sensors, the warning light will reset.
