S55 ticking/grinding sound when warm

[austinyellow]

Hey guys, first post here. I have a 2015 F80 M3 at around 85k miles and I'm getting this ticking/grinding sound at low RPM. It usually goes away at idle but I was able to catch it on video:

Anybody have any idea what this could be? It sounded like VANOS but I called around some shops that specialize in VANOS repairs and they said most likely it's something else since the systems are much more robust in the newer systems.

TIA

Did you find out what was wrong with the car ?
