How to reset the service reminder light on Audi 80?

I recently completed a service on my Audi 80 and now the service reminder light won't turn off. How can I reset it?

To reset the service reminder light, turn the ignition to the 'On' position, but don't start the car. Press and hold the odometer reset button, then turn the ignition off and back on again. Release the button and the light should turn off.

Another method is to disconnect the negative terminal of the battery for a few minutes. This will reset the car's computer and turn off the service reminder light.

If the light still won't turn off, you may need to use a diagnostic tool to reset it. This can be done at a dealership or with a specialized tool.
