Why does my Audi A8 engine rattle when idling?

It's possible that there could be an issue with your engine, but it's also possible that this is a normal characteristic of the Audi A8. Have you taken your car to a mechanic to have it checked out? They will be able to diagnose the issue and let you know if it's something to be concerned about.

I have an Audi A8 and have also noticed this rattling noise when idling. After doing some research, I found out that this is a common issue with Audi A8 engines. It occurs due to the direct injection system. My advice would be to schedule regular maintenance and have your mechanic keep an eye on it.
