What causes the check engine light to turn on in an Audi A2?

I recently noticed that my check engine light came on in my Audi A2. I'm not sure what could be causing it and if it's something I need to worry about. Any advice would be greatly appreciated

The check engine light can turn on for a variety of reasons. It could be a simple issue like a loose gas cap or a more serious problem with the engine. I recommend getting your car checked by a mechanic to determine the cause.

One possible cause of the check engine light turning on is a faulty oxygen sensor. This can affect the car's fuel economy and performance. I suggest bringing your car to a reputable repair shop to have it diagnosed and fixed.

Don't panic when you see the check engine light turn on. It could simply be a result of a loose gas cap or a minor engine issue. However, it's always better to err on the side of caution and have a professional check it out.
