The build date is 05/09 and apparently the correct part is 65410445684 as it was built after 03/09. Anyway the part arrived but the guy at BMW parts is saying now that this new part needs 'coding' or some kind of software update which the have quoted me 330 quid to do! This does not include fitting which they charge 2 hours labour for. Has anyone ever heard of this? Is there a cheaper way around it? Am I better off getting a different system fitted for say 500 quid total?
He sent me this to prove it
