At the last service in February, I asked the dealer for a remote control for my heater (Webasto) ex factory. I would have to know that the solution with the Webasto remote control and receiver in the car is no longer offered. Instead, this should now work via software and the normal car keys (see photo). Which buttons should be pressed there?? How is there a feedback?? About vehicle blinker? My dealer could not tell me exactly about this. .. but should cost 240,00 EUR and work with my key.. !? In BC there is the function Immediate start of the heater. Wouldn’t it be possible to use this function for an e.g. GSM box?? I would simply look for a line that activates the heater against mass or +12V switched on? Is this somehow possible? Does an AEM module have to be available for this? Does anyone know about this? Would I be happy about suggestions/answers. Thank you!
