Why does my Audi A1's check engine light keep turning on?

I have a 2014 Audi A1 and for the past month, the check engine light has been turning on and off. It's very frustrating and concerning. What could be causing this issue?

It is important to bring your car to a certified mechanic as soon as possible to diagnose the issue causing the check engine light to turn on. It could be a variety of things, from a loose gas cap to a more serious engine problem. Don't ignore the warning light!

Have you recently had any maintenance or repairs done on your car? Sometimes an incorrectly replaced gas cap or loose spark plugs can trigger the check engine light. Double check with your mechanic.

Another common cause of the check engine light is a problem with the oxygen sensor. It's a relatively easy fix, but it's best to take it to a professional to properly diagnose and replace the sensor.
