Hi one and all

I have a 2002 BMW X5 3.0d E53 and I need to know if the rear self levelling module needs to be coded when replaced.

I bought a good used unit , but when I plug it in , the diagnostic software doesn't acknowledge that the car has self levelling suspension.

I have been told by several 'used parts dealers' that it is simply plug and play , but not in my case.

Cannot seem to find an honest answer on Google , so I am hoping that there are some technical gurus here.
