How to troubleshoot a check engine light on an Audi A1?

The check engine light on my Audi A1 has turned on. What could be causing this and how can I fix it?

There could be multiple reasons why your check engine light has come on, such as an issue with the oxygen sensor or a loose gas cap. It's best to take your car to a certified mechanic to run a diagnostic and determine the exact cause.

In the meantime, make sure to check your gas cap and ensure it is tightly sealed. Sometimes a loose gas cap can trigger the check engine light. If the light stays on, take your car to a mechanic for further inspection.

Don't ignore the check engine light, as it could indicate a more serious issue with your car's engine. It's best to address the problem early on before it becomes a bigger and more expensive issue.
