Hi all I was having alot of trouble with the central locking and the actuall door lock itself, but after trawling the forums I found Colin Colin Abraham www.bmwgm5.co.uk 07790658683 This guy now's what he's talking about and he fixed my GM5, the door lock and ordered a new electronics board for the key fob. Any probs with the central locking give this guy a call. I would just like to say a big thankyou to Colin. Regards
