It had been starved of oil at some point while in BMW's hands.

Rod bearings and thrust bearings don't just magically deteriorate unless they are ran without oil.

An 89k mile good running car doesn't go to a rod knocking one at 90k miles if nothing has changed.

My whole gripe is that I believe a technician at BMW probably cranked or let the car run while doing oil filter housing gasket or turbo oil line repair job and that caused the bearings ( unsure if thrust or rod at this point) to get beat up and start knocking.
I agree with you but I'm not sure that they should have caught it b/c I think based on what I have read so far that the problem may have been worsened in the last couple of visits.
