Though this is rare, it's worth noting you need to check the belt routing before ordering the pump. I replaced my PS pump and got the correct pump the first time. Didn't have to change anything else.
I confirmed with my BMW parts guy and there is indeed 2 different part numbers for each rotation direction.

My 2009 (build date 11/08) has the old belt routing.

my shop ordered my pump through an online distributor from somewhere else other than bmw and i am estimating that it's the wrong pump. they advised that my entire steering rack is the culprit. i'm just trying to confirm that it's not the wrong pump in there. they also stated that perhaps the culprit of the entire situation is my 275 tires on 19x10 wheels. my opinion is that it should not have affected it because 1) I do not track my car 2) the over all diameter is the same and the wheels are actually as light or lighter than oem 18x8.5s and tire combo. I weighed them. they are lighter than the zcp or 220s.
