Why is there a red check engine light on in my Audi A3?

I recently noticed that the red check engine light has turned on in my Audi A3. It has been running smoothly and I have not noticed any changes in the performance. What could be the cause of this warning light and how should I address it?

The red check engine light indicates a problem with the engine that needs immediate attention. It could be due to a malfunctioning sensor or a serious issue with the engine itself. I recommend taking your car to a certified Audi mechanic as soon as possible to diagnose the problem.

Sometimes the check engine light can be triggered by a loose gas cap. Make sure yours is tightly closed and drive your car for a few days to see if the light turns off. If it doesn't, it's best to get a professional opinion from a mechanic.
