Hi guys

Trying to diagnose a couple of issues with my new 4.8is.

There is a rattling noise from the engine. Definitely sounds like it's coming from the top end. More noticeable on the nearside, but seems to be both sides.

You can also hear the noise well from the front wheel arches as well.

I've taken two video's to show the issue (24 and 43 seconds so kept it short and sharp!) Can you guys take a look and let me know what you think:

VIDEO 1 (inside engine bay):

VIDEO 2 (outside car and wheel arches):

What do you think is the likely culprit here?

Thanks guys!
