Anyone had one of these replaced and can give me an idea how much it cost? Dealer said I need one but there system was down so they couldn't tell me how much it was.

Symptons were my remote locking not working and neither is the rear window glass button. They had thought it was the aeriel diversity module under the rear roof spoiler (e61) so I bought one and replaced it and it didn't fix it.

I think its item 7 on this page of realoem but not 100% http://www.realoem.com/bmw/showparts.do?mo...hg=61&fg=25

If I knew where it was I could check the connections as a member on here reported that his had a problem and it was a loose wire! That would be too easy.
