My Ride: 2002 325Ci

Then, I got my iPhone 4 (thank goodness for the LED flash, I never thought that thing would ever come in handy...) and tried angling it where the VR was (I'd say that this requires some dexterity, and even then, expect a whole lot of trial & error) and by luck, after taking countless photos with my iPhone 4's camera, I was able to find out my VR was a Bosch 120A. You can probably do the same with a small mirror (key word: SMALL) but regardless of which way you choose to find out which VR you have, that's the way I decided to go about with it.

Hope this helps!

that does help thanks. So was that all you had to remove to replace the regulator? or did you have to remove the fan or anything like that. It seems to be a pretty tight fit in there.
