The electronics in the E53 sometimes have a mind of their own. Personally, this is why I like the iDrive cars because I can 'program' this stuff myself (in my 545 it is like this) in the X however, you have to rely on a dealer to do..whatever it is...they do.

The scary part to electrical gremlins is you don't know where or when they will pop up again, I would much rather has a consistent issue then a miracle fix.

Here is a question, did you disconnect the battery when you changed the wiper motor? If so, this probably reset your settings and 'fixed' your issues.
