The X3 MkIV will work, but I'm not sure about the Z4 :dunno:

See http://www.bimmerboard.com/forums/posts/217370 for a listing of part numbers.

Thanks Everyone For All Your Comments, I Have Now Installed The Mk4 Into The Car And Everything Is Working Fine, Bought It From Ebay So Saved A Good Few Quid, Very Happy.

Just Need To Get The Phone Sorted Now! Cheers Again:)

:thumbup: Congrats!!

Wot he said :thumbup: Glad you got it sorted.

Re. realoem - I have found that often the parts search doesn't work - best bet is to key in all the info on your car and go to the relevant section.
