Enable Trailer Control Module
2016 V60 towbar fitted using Volvo wiring kit. Now needs TCM "enabling" i.e software amendment/upgrade for the module. Dealer quote is £80.95!
The car was only serviced a couple of months ago and allegedly software checked and upgraded, so the rest of it should be up to date.
I gather the Diagnostics are standard OBD2 fitting (?) used by many auto electricians, so is there any source, OTHER than the dealers, for the software?
