Why does the check engine light randomly turn on in my Audi A3?

I noticed that the check engine light in my Audi A3 turns on at random times, even when the car is running perfectly fine. What could be causing this issue?

There could be several reasons for this issue, such as a faulty sensor or a loose gas cap. It's best to take your car to a mechanic and have them run a diagnostic check to determine the exact cause.

It's possible that there is an issue with the electrical system in your car. I recommend taking it to a trusted mechanic who is familiar with Audi vehicles to have it checked out.
