Hello together, since Monday the heating in the E-operation (Pure or Hybrid) no longer heats, it is asscold. In the climate control the additional heating is activated. Also via the app the pre-climateization with connected charging cable can no longer start. As soon as I switch on the burner, it becomes warm. First remote diagnosis of the workshop: electrical heating module defective. High-voltage team however overloaded, therefore no remedy at short notice. Nevertheless appointment on Thursday “to read out the error memory”. Is this a known problem and how complicated are the works? It was written in the forum already a lot about stand heating/Zusazuheizung etc… Fröstelnde Greetings
