Not looking good then.
I have been told about a V40 with the same interior as mine, that is in a scrap yard after an accident and it has the winter pack fitted. so was thinking if I got the seats and switches from it I could swop them into my car. But if it will need to be programmed and the dealer will not do it, then it's a no go.
I even wondered if I could get an upgrade to heated seat done by the dealer, but they only fit it to new cars.
Think I need to get hold of a centre console to take apart and see if there is any way to mount an aftermarket switch using the Volvo switch face.
