Hi all, tried asking this in the V50 section but no luck. Anyone know?

I've just fitted to my 2009 V50 a second hand towbar which came with a used volvo trailer module. This is currently plugged in and powered up but not doing anything as the car presumably isn't talking to it. Does anyone know for definite if this module can be reprogrammed and used? Local dealer wasn't sure but thought if it hadn't been de-registered from its original car, they wouldn't be able to code it to a new one. Does that sound right? If so would seem to make all the second hand units for sale on the internet worthless! I'm guessing its the CEM that actually gets reprogrammed, to look for the trailer module with the correct serial number?
Towbar came from a scrap yard so doubt the original car still exists!
