How do I reset my service light on an Audi A2?

I have an older Audi A2 and the service light has been on for a while now. How do I reset it without taking it to a dealership?

First, try pressing and holding the trip meter button while turning on the ignition. This should reset the service light. If that doesn't work, you can also try disconnecting the car battery for a few minutes and then reconnecting it.

If the above methods don't work, you may need to use a diagnostic tool to reset the service light. You can purchase one online or borrow one from a friend or local mechanic.
