Why is the engine light on in my Audi A6?

I recently noticed that the engine light on my Audi A6 has turned on. It's been driving normally, but I'm concerned about the potential implications and how to address the issue. Can anyone offer any insight or advice on what may be causing this and what steps I should take to resolve it?

The engine light could indicate a minor issue, such as a loose gas cap, or it could be a sign of a more serious problem. It's important to have it checked out by a professional mechanic as soon as possible to properly diagnose the issue. In the meantime, try tightening the gas cap to see if that turns off the light.
