2010 X5M exhaust "flaps" mettalic rattling sound?

predicate_logic · 03-14-2021, 02:32 PM

Hi everyone, I have been hearing a metallic "rattling" noise at startup and while driving.

(I don't hear the rattling at idle).

I THINK I've found where it's coming from: the flaps in the exhaust tips.

Has anyone had rattling noises from these? How do you fix this properly? Thanks in advance.

It looks like you need WD40.
I had the same problem. You can use WD40 spray valve link and link point.
