E53 temic airbag module coding 65 77 6900727

[PaperBackWriter]

Good afternoon all.I am new to the forum, first time caller long time listener etc. I have done plenty of mechanical work on the car so will chip in when I can. In the meantime I have a 2001 e53 4.4I sport on which the airbag module developed the cold weather fault that gradually become an almost all weather fault. It throws a 240 internal error code on inpa unless its warm then its fine. I swapped the module for another one that was not happy with the rear airbags. You can clear the fault but it returns on the start up self check. I swapped it again for a further used module, same fault. The internet says these modules are coded for configuration rather than to the car. Both replacements are from x5s of the same age. I have had 2 BMW specialists try and re code the modules and say they can't but that there are people put there with lap tops who can. My question is what people and what laptops because I can't find them? BMW say they will have a go for £99 plus vat but say they have never done a used one. They cannot sell me a new one until august as they out of stock worldwide. The car now has no mot due to the airbag light. Any help appreciated
