Hall oils, so heating is in, so far as it works. Works in itself, but have the following problem. Heating turns on (or I switch on manually), it starts, starts to heat. Then after a short time the Klimatronic starts, and the ventilation starts at a very low level. The whole thing lasts about 30 sec. then the Klimatronic stays, but the ventilation is still silent. Is that so normal? I thought that the blower is running on higher tours to heat up the interior. K Limatronic seems to be going when I’m driving. I connected the plan to pin 9 grey plug from the Klimatronic. Is there a separate progamm started? Or do I still have a mistake in thinking somewhere? Would I be happy about help.
