Did they use the genuine Volvo ecltrical system that just plugs onto the vehicle electrics? It will need a software update to work completely but should work all the lights without the software. The software switches off the rear fogs when the van is attached, checks the lights are working and modifies the Traction control to work with the caravan in the event of snaking starting.
From what you describe they did not and have cobbled together a system that clearly does not work. Take it back and get them to fix it. |
