hd750Li: Thanks! I'll check it out
Today, I noticed when pressing on the grey areas of the AC-panel the temperature and blowing speed turned red in the display above the AC-panel. Pressure did not induce the sudden heat. However, the car had been driven for only 15 minutes. On Thursday, I have to make a longer run and then I'll try it again.
BUT, I found a panel on the German eBay for only 50$, in case the panel is the culprit
