I have read in multiple people having same issue of metal in oil and primary cause is VANOS bolt shearing and causing debris in engine oil. In worst cases the bolts backs out of the camshaft which is catastrophic to the engine.
I am counting on that.

Can you post links about the vanos bolt shearing you have found? I have not heard of this on the N63 engine before.
I could really only see that happening if the bolt was reused for some reason.
