How can I reset the service light on an Audi 80?

The service light has been on for a while on my Audi 80 and I'm not sure how to reset it. I've tried some online methods, but they didn't work. Any help would be appreciated. Thanks!

To reset the service light on your Audi 80, start by turning on the ignition without starting the engine. Then, press the trip reset button and hold it for about 10 seconds. The service light should begin to flash and then turn off. Release the button and turn off the ignition. It should now be reset. Hope this helps!

If the above method doesn't work, try this: with the ignition off, push and hold the odometer reset button. While holding it, turn on the ignition but don't start the engine. Wait for the word "service" to appear on the display and then release the button. Use the trip/reset button to navigate to the reset option and then press and hold the button until the display flashes. Release the button and turn off the ignition. Your service light should now be reset.
