Range Rover Vogue 2010 PDC no power
 

Hello, new member, so apologies if this particular problem has been addressed before.
Recently got a super RR Zermatt 5.0lt SC, for SWMBO, wow what an engine!
It is a used car with a full service history with the obvious glitches, side view cameras blue screen for one and no power or anything from the PDC system.

I have checked fuses, ok, and changed the PDC module. Have had a diagnostic computer plugged in, it says the module cannot communicate with the ECU. (probably due to there being no power to the system)

Has anyone else experienced this problem, if so HELP!!

Many thanks
