Dear forum! I have problems with the heating power of my car and would like to get to the bottom of the matter. Although the heating is very fast, after a kilometer lukewarm air comes out of the heating system. But unfortunately this lukewarm air does not get much warmer even after longer driving. I was yesterday in the workshop where the software was checked and no problem was found (everything without calculation and under guarantee). I would be interested if some have the same problem or if one has to accept the nevertheless weak heating power. Lg Michael H.
