What does it mean when the check engine light in my Audi A1 turns on?

I noticed that the check engine light in my Audi A1 has turned on and I'm not sure what that means. Is it something serious? Should I take it to a mechanic?

The check engine light in your Audi A1 turning on can indicate a variety of potential issues. It could be something as minor as a loose gas cap, or as serious as a malfunctioning engine component. It's always best to have it checked out by a mechanic to be sure.

In my experience, the check engine light in an Audi A1 is often triggered by a faulty oxygen sensor. This can cause a decrease in fuel efficiency and potentially damage your engine if left unchecked. I would recommend getting it looked at by a mechanic as soon as possible.

I've had my Audi A1 for years now and have dealt with the check engine light coming on multiple times. In my case, it was usually due to a loose gas cap. However, it's always better to err on the side of caution and get it checked by a mechanic just in case.
