How do I reset the check engine light on my Audi?

I recently had some work done on my Audi and the check engine light came on. How can I reset it myself without going back to the mechanic?

In order to reset the check engine light, you can try disconnecting the negative battery terminal for a few minutes and then reconnect it. If that doesn't work, you may need to use an OBD-II scanner to reset the code.

Another option is to drive the car for about 100 miles and the light should turn off on its own. This is only recommended if you know the issue has been fixed and you're just waiting for the light to reset.
