How can I reset the check engine light on my Audi 80?

I recently had some maintenance done on my Audi 80 and the mechanic told me that the check engine light may come on until the car's computer resets. It's been a few days and the light is still on. How can I manually reset it?

To reset the check engine light on your Audi 80, you can try disconnecting the battery for a few minutes and then reconnecting it. This can sometimes reset the car's computer and turn off the check engine light.

Another option is to use an OBD-II scanner to clear the trouble codes and turn off the check engine light. You can either purchase one or borrow one from a friend or auto parts store.

If the light continues to stay on, it's best to take your Audi 80 to a mechanic or dealership to have them perform a diagnostic test. They will be able to identify any underlying issues that may be causing the light to stay on.
