Why is my Audi A1 displaying the check engine light?

I have noticed that the check engine light in my Audi A1 has turned on unexpectedly. Can anyone explain possible reasons for this and how to fix it?

The check engine light can turn on for various reasons, such as a loose gas cap or a faulty oxygen sensor. It is best to have a professional diagnostic test done to determine the exact cause.

I had a similar issue with my Audi A1 and it turned out to be a faulty catalytic converter. It is important to get this checked and replaced if necessary to avoid further damage to your car.

Before heading to the mechanic, try tightening your gas cap and see if the check engine light turns off. If not, then it is most likely a different issue and you should bring it in for a diagnosis.
