How do I reset the check engine light in an Audi 80?

I recently purchased an Audi 80 and the check engine light has been consistently on. I've taken it to a mechanic and they were unable to find any issues. How can I reset the check engine light myself?

To reset the check engine light in your Audi 80, first ensure that your gas cap is tightly closed. If it is not, this could be the cause of the issue. If the light remains on, you can try disconnecting the battery for a few minutes and then reconnecting. If the light persists, it may be best to take it to a certified mechanic for further inspection.

One thing you can try is using an OBD-II scanner to identify the specific issue triggering the check engine light. By knowing the specific error code, you can research potential solutions or take the information to a mechanic for assistance. Some auto parts stores also offer free scans if you do not have access to a scanner.
