My car is a 2011 528. I am having trouble to bring outside air into the car at ambient temperature. If the air conditioning is off and the engine is at running temperature, air coming in is always warmer than the outside. I tried to switch the Air system on and off and changing the temperature setting, doesn’t make any difference. I took the car to dealer twice and also wrote to BMW Canada. The dealer had the car for three days each time and finally I was told that there is nothing they could do and that is the way the car is designed.
When the outside air is around 18–21 °C, I just don’t want air conditioning. It is frustrated.
Friends, if you are considering a new 5, check out the air system first.
