How do I troubleshoot the engine light on my Audi A3?

I recently noticed that the engine light has turned on in my Audi A3. How can I troubleshoot this issue and potentially fix it myself?

The engine light could be indicating a variety of issues such as a loose gas cap or a faulty oxygen sensor. It's best to get it diagnosed by a professional mechanic.

You can try checking the error code with an OBD-II scanner and researching possible solutions online. However, it's always recommended to have a professional look at it if you're unsure.
