I have noticed a broken oil filter housing mount on my car (and fixed it) and then today I saw the exact same problem on another M5, so I post some info.
I think the reason the rubber mount broke might be stress from when tightening the oil filter cap with a torque wrench without holding the housing with the other hand thus letting the rubber mounts absorb the torque.
The oil filter housing is held in place by two rubber mounts. There are two screws moulded into each rubber mount.
Th eoil filter housing is secured to the rubber mount by two nuts. the nuts are reusable.
The rubber mountings are screwed into nuts which are welded to the holder.
To remove an unbroken but cracked rubber mount, just grip its top side screw with a pair of pliers and turn it.
To remove a broken rubber mount, grip the screw on the BOTTOM SIDE of the holder with a suitably small pair of pliers. (If you try to grip the broken rubber part on the top side, you will probably just scratch the holder. Bin there...)

The steering servo fluid reservoir is located next to the oil filter housing. It is mounted in a similair way. On both cars the rubber mounts for thr servo fluid reservoir showed cracks.
This is very common on the E39 V8s. I think I have replaced 3 on my M5 alone, and countless others. It is an important thing to check out as without the oil filter housing pulls on the oil lines and can create a massive oil leak. Thanks for posting this David.
I just had my oil changed at a local dealer last weekend.
I go to check the oil the following Tuesday and find the same problem. It was clearly done when the tech tightened the cap.
Returned to the dealer and I am waiting for the part.
I was actually considering trying to fix the problem by drilling through the remainig rubber on the broken side and pushing a longer screw through the hole and using the old bolt. but then again, if I did not break it why should I try and fix it.
funny thing is I was wondering if this happens frequently since the design seems open to this type of failure. Does anyone know why BMW wanted to have the filter housing mounted on rubber bushings instead of being attached to the block like an E36?
Gotta love this board. I would have never thought to check that until when I went to change my oil in another 6k miles or so as I just had Inspection II done at the dealer. Well, I go out to check and what do I find, one of the mounts is broken. It was not broken when I changed the oil 7k miles ago, so the dealer did it.
I'm just going to fix it myself though. A few bucks in parts is worth the hours I'll have to waste with the dealer.
Was going to start a new thread about this, but thank god I didn't... Did the oil on my girls car and found both mounts broken. I had to tie wrap the filter housing for now, but I need those mounts. Anywhere other than BMW, or maybe online ?????

"Is it the sounds that make a BMW a BMW? A BMW is designed to be heard, felt, experienced. So our engines sing. Our steering talks back. And we insist on offering manual transmissions in nearly all our models for drivers who crave them. The result is an almost telepathic oneness with the car. Just as surely as you can hear a BMW, a BMW hears you."
