I have a 2011 R1200GS and someone pointed out to me today that the rear drive has a breather, which I understand is a part of BMW's ongoing efforts to minimize rear drive failures due to pressure fluctuations.

I can't find the breather's installation\removal described in my BMW Service manual for the bike.

Does anybody now how to remove\install it? I can see the exterior rubber boot but am wondering how it is installed\removed?

Thanks for any education that you can provide.
