I’m currently thinking about retrofitting a heater with my S80. I don’t know if I really do it yet. Here in the north, really cold days are very rare, but if they are there, it would be quite nice to have one. The heater of the diesel is getting a lot of criticism here. Is the Volvo stand heater for petrolers the same, or has nothing to do with it? I have also requested an offer for a Webasto Thermo Top P or C, according to my friend However, the Volvo SH is also produced by Webasto. Does anyone have any experience in retrofitting the different variants of petrol engines? Marcel
