Well,
I am not too sure if the PDC is part of the optical bus, or on one of the K/L/I Lines of the vehicle.
If it is part of the optical bus, we would need to break into it, and then reconfigure/rescan the optical bus to detect the new module, this I have the tools for. This is the likely scenario
If it is part of the L/I line or another bus which is another posibility, the change would have to be made to the ZCS or FA coding, which I have the tools for, but have not done yet.
Hence the "I believe" i have the tools for
Would be keen to try this though, everytime I do, I learn :0
By the way, does anybody know if the E60 uses byteflite, or was that limited to the E65
