Moin, since it was a bit colder here in the north around the weekend, I wanted to use the heater. Not that that gets bored. On Thursday I noticed that the SH was off after I had started the car. But I wasn’t sure if it was already running for 20 minutes. So this morning started again by hand transmitter. At the car arrived, it was heard that the heating was running and in the interior it was nice warm. When I then turned on the ignition (motor not I could not turn on the SH via the ZAB again. The SH was changed at the beginning of the year. Probably the ones in the workshop have programmed something wrong or what do the experts say here? Gruss RocketRider
