Hi, the heating in my 1993 9000CE (no ACC) does not work proberly, since yesterday the heat if turned on fully is approx. one third as it was before. The temperature indicator is always on the lower end, the display says check engine, but the motor has its usual temperature, but the hoses and the radiator are only a bit warm (after about 50km with an average of
120km/h, weather is about -5degree celsius). The coolant level is on maximum. Three months ago the radiator was replaced, the whole cooling system checked and filled properly.What could be the matter ?
Greetings Axel
