On diagnostic laptop it gives some error like "Comunnication of the main computer with air condition computer error". Something like that. Can anyone help me or maybe someone had this stupid problem ? Could it be that air condition part with wheels inside the cabin is not working ? I am really lost and even in BMW garage they dont know what it is. They all thought that it is compressor but my mechanic connected it directly with a wire and then the AC works, air is cold. But when connected on the car it does not trigger anything. And also he says that the car shows zeros on AC pressure but the gas and pressure is there. He tried to change indicator of gas pressure on compressor and still nothing. My car is BMW 320d E90 Year 2007.
Thanks a lot
