Why is the Audi A8 engine making a rattling noise?

I recently purchased an Audi A8 and have noticed a rattling noise coming from the engine. Is this normal or should I be concerned? What could be causing the noise? Any advice on how to fix it?

It is not normal for an engine to make a rattling noise, you should definitely have it checked out by a mechanic. It could be a sign of a larger issue that needs to be addressed.

I had a similar issue with my Audi A8 and it turned out to be a loose component in the engine. Make sure to have it checked and tightened by a professional.
