How do I reset the service warning light on the Audi A3?

I recently got a service on my Audi A3 and the warning light is still on. How can I reset it myself without going back to the mechanic?

To reset the service warning light on your Audi A3, follow these steps: 1. Turn off your car's ignition. 2. Press and hold the '0.0' button on the dashboard. 3. While holding the button, turn your ignition on, but do not start the engine. 4. You will see the message 'Reset oil change interval?' Press and hold the 'OK' button. 5. Release both buttons when the light goes off. 6. Turn off the ignition and wait for a few seconds. 7. Start your engine and the service warning light should be reset.
