Hello dear members of the forum, a lot has already been written about the topic of ventilation at the Omega. However, I am faced with a problem which also causes perplexity among the experts of Opel: After the start of my Omega B, 2.2 the heating works as desired. All windows are free, the room temperature corresponds to the pre-selected temperature (air conditioning automatic). However, if the vehicle is then parked and driven again after about 30 minutes, such as after a purchase, After a short period of time, the discs are very heavy. There is nothing to do with ventilation at the highest level…. The same happens even after continuous driving, about 60 minutes after the start of the journey. Everything has already been checked with Opel: processes, actuators, ventilation valves, control electronics etc. No errors can be detected. Does anyone know a similar problem or even advice? Thanks in advance
