Well, after I had the software for the preheater installed last week and I wanted to try the heater in the last few days, it didn’t run… Today I went to another Volvo dealer, who looked at it. Fact is: the software is installed, the preheater is not ( I have a French XC90 ) Now the Volvo dealer tells me: Preheater with installation costs with it EUR 2200…. Ziemlic proud price as I find…. I will be in winter I’m gonna have to scratch.
