Why is my Audi A5 Check Engine Light On?

I recently noticed that the check engine light on my Audi A5 has turned on. I'm not sure why this has happened and I'm worried that there may be a serious issue. What could be causing this and what steps should I take to resolve it?

The check engine light in your Audi A5 can indicate a variety of issues, ranging from a loose gas cap to a more serious engine problem. It's important to get your car diagnosed as soon as possible, as even seemingly minor issues can damage your car over time. I recommend taking your car to a trusted mechanic or dealership to get a diagnostic test done.
