How to fix my Audi A3's faulty engine light?

My 2015 Audi A3's engine light keeps turning on every time I drive it. What could be causing this issue and how can I fix it?

The most common cause of your engine light turning on could be a faulty oxygen sensor. It is recommended to take your car to a mechanic to get it diagnosed and replaced if needed.

Make sure your gas cap is properly closed and secured. A loose gas cap can also trigger the engine light. If this doesn't solve the issue, it's best to get it checked by a professional.
