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

I noticed that the check engine light has turned on in my Audi A2. What could be causing this issue and what steps should I take to address it?

As a first step, you can check your gas cap to make sure it is properly tightened. If that doesn't resolve the issue, it could be caused by a variety of factors such as a faulty O2 sensor or a loose electrical connection. It's best to take your car to a mechanic to have it properly diagnosed and fixed.

The check engine light turning on can indicate a wide range of issues, from a minor glitch to a more serious problem. I would recommend taking your Audi A2 to a certified mechanic to run a diagnostic and determine the exact cause. Ignoring the light could lead to more costly repairs in the long run.
