Hey guys, I just switched all 6 spark plugs with new proper spec ones, as well as a failing ignition coil (previously had a misfire and code gave it as ignition coil fault).
Anyways now I put everything back together, and I’m
hearing a new knocking noise that gets worse with higher RPM🥲. I’m trying to think what could be the cause, I torqued every spark plug to spec (23nm) I checked the cylinders with a bore scope for any debris before reinstalling the intake manifold.

Part of me feels like the culprit might be the serpentine belt? Maybe it’s just wishful thinking, some help please🙏

Hey guys, I’ve been hearing a weird thump/popping noise coming from the rear of my 4matic c300 when driving on bumpy surfaces.
I can’t seem to figure out what the problem exactly is, do yall have any idea?
The noise began after hitting a pothole on the highway (shitty Quebec roads) like 2 weeks ago.

I checked the shock absorber for any liquid, nothing.
I also checked the ball joint and tire rod, both seem fine.

This is a video of me bouncing the rear trying to pinpoint where it’s coming from exactly
