How to troubleshoot a check engine light in Audi A7?

My check engine light keeps turning on in my Audi A7. What steps can I take to troubleshoot and fix the issue?

First, make sure your gas cap is properly sealed. A loose gas cap can trigger the check engine light. If the issue persists, check for any noticeable changes in the car’s performance or any strange noises. You can also visit a mechanic or use an OBD-II scanner to get a more specific diagnosis.

If your car is still under warranty, it's best to take it to an authorized Audi dealership for any check engine light issues. They will be able to diagnose and fix the issue free of charge. If your warranty has expired, consider contacting a trusted mechanic for a cost-effective solution.
