Moin, let’s ask a question about the possibility to upgrade the original heater of the Phaeton with a telemodule. Is it possible to activate the heating by phone (either as sms or via app)? I would like to activate the Sztand heater in the car from a distance, because it is outside the FB range during the day and can be preheated for work in winter. It is a GP3 TDI long from BJ 2013 with VA outside refrigerator and R Dear Seat, otherwise everything is installed. Many greetings and thanks for replies kt 14101
