On my 97s I still have a problem with the regulation. If the outside temperatures are so below 15 degrees and I need heat, then the regulation is no problem at all. But if it is warmer outside or I drive like yesterday long distances, so longer than 1 hour and the interior or engine compartment is heated up accordingly, then the ACC cools too much down. If then I want a pleasant indoor temperature, then I have to go at least to 26 degrees so that it is less k Yesterday in the late afternoon I had an outside temperature of 15 degrees and the ACC cooled like stupid. ACC was not the solution either, because then the full 15 degrees came in from outside. So far I have already changed the following, because I can change the components between the two 9000s at any time and these parts in my second elk function easily. ACC, interior sensor, the long metal sensor in the distribution range, the engine hit for the control the flaps and the sunlight sensor on top of the dashboard. I have already changed the complete combination ACC and interior sensor between both cars, all helped nothing. I get the temperature down a bit, but not as comfortable as I am used to. Which sensors still have an influence on the regulation, because the problem always comes after a longer journey, which becomes particularly annoying on long holiday trips. Just like it is current for me, the fault must come from the vehicle itself and not from the components, since they are running in the second without interference. Perhaps there is a fault over the wire harness or or… Does any of the remaining owners have an idea? Greeting rpe 9000
