How can I reset the service indicator in an Audi 80?

I recently had my Audi 80 serviced, and the service indicator light is now on. However, I would like to reset it myself instead of taking it back to the dealer. How can I do this?

To reset the service indicator in an Audi 80, turn the key in the ignition to the 'On' position without starting the car. Hold down the '0.0' or 'reset' button on the dashboard until a message appears saying 'Reset'. Release the button and turn off the ignition. This should reset the service indicator.
