Why does the Audi A2 sometimes experience issues with the engine light coming on?

I've noticed that my Audi A2 occasionally has the engine light come on, even though everything seems to be running fine. What could be causing this and how can I address it?

It is possible that there is an issue with the oxygen sensor in your Audi A2. This can cause the engine light to come on, even though everything else seems normal. It is important to get this checked out as it could lead to further problems if left unaddressed.

Another common issue that can cause the engine light to come on is a loose or damaged gas cap. If the cap is not tightly sealed, it can cause the EVAP (evaporative emission system) to detect a leak and trigger the engine light. Simply tightening or replacing the gas cap can often solve this issue.
