Won't the part be damaged if you try to refit it ?
If BMW assembles parts on cars like they do on thier motorcycles, they usually specify assembling parts like this with interference fitting or shrink fitting the parts together, by chilling the insert and heating the receptacle, and then pressing it in.
Sometimes you can get away by pressing it in once without shrink fitting it. But if you press it out again it might deform or remove some metal and it might not go back in tight enough after pressing it in and out 3 times.
Would hate see you stuck with a bad part that was not assembled right in the first place.
