Body Control Module Replacement

Has anyone ever changed the body control module on a disco 4 ?
If you have did you have to get it programmed to the car and by what method, iid tool perhaps.
Is it even possible to replace the BCM ??

My BCM is not giving me any live outputs to the GAP Tool for anything to do with battery or alternator, all it shows is N/A.
I have updated the BCM to the latest software and replaced both batteries and the alternator but still no output being read by the GAP Tool?

On some D4 models, they also need a KVM at the same time

Thanks Mikey
I believe the KVM is rather expensive is it not?
If it came to that I would pull my BCM and take a look for anything untoward, maybe a loose/corroded connection.
