Why does my Audi A1 have a check engine light on?

I recently noticed that my Audi A1's check engine light has been on. What could be causing this and what should I do?

The check engine light can indicate a variety of issues, from a loose gas cap to a more serious engine malfunction. I recommend taking your Audi A1 to a trusted mechanic to have it diagnosed and fixed as soon as possible.

One common reason for the check engine light to turn on is a faulty oxygen sensor. This can negatively affect your vehicle's performance and fuel efficiency. I suggest getting it checked out and replaced if necessary.

Sometimes the check engine light can come on due to a problem with the catalytic converter. This is an important emissions control component, so it's best to get it checked out by a professional promptly.
