What should I do if my Audi A6's check engine light is on?

Last night, my check engine light turned on while I was driving my Audi A6. What could be causing this and what should I do?

First, don't panic. Seeing the check engine light is never a fun experience, but it's important to stay calm and take action. It could be something as simple as a loose gas cap, or something more serious like a faulty oxygen sensor. The best thing to do is to have your car scanned for error codes at a reputable auto shop. They'll be able to diagnose the issue and give you more specific advice on how to proceed.

One important thing to keep in mind is that driving with the check engine light on can cause further damage to your car. So if your check engine light is on, it's a good idea to pull over to a safe location and turn off your engine. You can also try tightening your gas cap and restarting your car. If the light doesn't turn off, then it's best to take your car to a mechanic.

It's also worth mentioning that the check engine light will not turn off on its own. Even if the issue is resolved, the light will remain on until it is manually reset. So make sure to take your car to a mechanic or use an OBD scanner to reset the light once the issue has been addressed.
