Why is my Audi A6's engine light on and how can I fix it?

My Audi A6's engine light has been on for a few days now. Is this something serious and is there anything I can do to fix it myself?

In my experience, the engine light can come on for a variety of reasons. It's important to get it checked out by a mechanic as soon as possible to avoid any potential issues.

I had the same issue with my Audi A6 and it turned out to be a faulty oxygen sensor. I would recommend taking it to a certified Audi mechanic to get it properly diagnosed.

I would suggest checking your gas cap first, as a loose or faulty gas cap can cause the engine light to come on. If that doesn't solve the issue, it's best to bring it to a professional for a proper diagnosis.
