No it doesn't fit, but its an example of how it fixes the problem on the X3 which looks prone to fail more from what it looks like searching a bit... Most of the failed transfer case I've seen reported in various bmw forums are those plastic worm gear that gets worn out over time from moving from the exact same path over and over until all the plastic is consumed... Some think that it it a bad idea to replace these by a metal part as if for some reason the transfer case refuses to move internally (the scissor action) then that plastic part is the weak point of failure and it would fail much nicely than forcing the transfer case mechanics... But is this really a concern? I dunno...
