Why is my Audi A8 displaying the check engine light?

I recently got a check engine light on my Audi A8 and I'm not sure what it means. The car seems to be running fine, so I'm not sure if it's something I need to immediately address or if it can wait.

The check engine light can indicate a variety of issues, ranging from minor to more serious. It's best to have a diagnostic test done by a certified mechanic to determine the specific cause and address it accordingly.

The check engine light is a warning sign from your car's onboard computer that something may be wrong. It's always better to err on the side of caution and get it checked out sooner rather than later. It could potentially save you from more costly repairs down the road.
