Why does my BMW M8 engine make a rattling noise at high RPMs?

I recently noticed that my BMW M8's engine seems to make a rattling noise when I push it to higher RPMs. It's been running smoothly up until now, so I'm wondering what could be causing this and if it's something I should be concerned about.

Based on your description, it's possible that your M8's engine is experiencing a timing chain issue. This can cause a rattling noise at high RPMs and can be a costly repair if not addressed promptly.

Another possible cause could be a loose or worn out auxiliary belt. I would suggest having a mechanic check the belt tension and condition to see if it needs to be replaced.
