^would these newer ones work with my car? If not, why not, computer related?

Im trying to get my part #'s and items straight, since i have a big day at the BMW junkyard tomorrow.

i don't even think that the obd 2 have the bolt holes in the same position as the obd1, that would be your first obstacle...
