What do I do if my Audi A2's check engine light is on?

I recently noticed that the check engine light on my Audi A2 has turned on. What could be the cause of this and how can I fix it?

The check engine light could indicate various issues with your vehicle, such as a faulty oxygen sensor, loose gas cap, or even a misfiring engine. It's best to take your car to a mechanic for a diagnostic test to determine the specific problem and how to fix it.

Make sure to check your gas cap first, as a loose cap can cause the check engine light to turn on. If the cap is tight and the light stays on, it's likely a more serious issue. Don't ignore the light and schedule an appointment with a trusted mechanic as soon as possible.
