How can I reset the service light on my Audi A2 using my car's computer?

I recently got an oil change on my Audi A2, but the service light is still on. How can I reset it using the car's computer without having to take it back to the mechanic?

You can reset the service light by following these steps: 1. Turn the ignition to the on position without starting the engine. 2. Press and hold the trip meter reset button. 3. While holding the button, turn the ignition off and then back on. 4. Release the button when the service light starts flashing. 5. Press and hold the button again until the light stops flashing. Your service light should now be reset!
