Hello Elchgemeinde. It is again about a ’00 TDI with automatic climate control. We went before without activated air conditioning, with switched on ventilation (faith automatic position) about 1km to shopping. After 2x parking for approx. 10min with slightly opened windows and 40m between the parking lots, it smelled when getting on to rotted plastic. Short check behind the radio (had recently built a new radio, therefore the glove compartment was already outside) climate control part and below After 10 meters of driving, plastic smoke blew towards me through the two middle nozzles. The shock sat and I immediately switched off the ignition and the children evacuated or can do it quite well themselves. I checked afterwards: the fan, the radio and the air conditioning unit. I left the latter outside and removed the plug at the rear of the air conditioning box (picture) and drove home without having to smoke again. 1. I Can this happen if the control flap adjustment has never been performed? I have heard a flapper/running probably the control motors in the dashboard from time to time. Nozzle adjustment via dial wheel has been problem-free so far. 3. How do I proceed now? 4. Can the ventilation/climate be used for the first time if the control position remains in a position so that the control motor is not controlled again and completely burns? Or is it a bit ga Thank you for your help.
