How Do I Clear Audi Diagnostics Codes?

1. Hook the code scanner up to the Audi's diagnostic outlet. You will find this beneath the dash on the driver's side.
2. Power up the scanner.
3. Turn the key in the ignition, but not all the way. You want the electrical system to come on, but not the engine itself.
4. Wait as the scanner and the Audi's computer communicate. The old code warning should show on the scanner.
5. Press 'Clear' on the scanner. This should wipe the diagnostic message off the Audi's computer.
6. Repeat these steps if you want to double-check. The scanner should not detect a code if you try this a second time.
