One day recently in BrisVegas, the temperature reached 39/40 degrees C. I generally have my air con set to "Fresh air", however due to the extreme heat in the car whilst parked, I hit the "Recirc air" button and noticed there was no change in the intake airflow, although the symbol on the display changed. Normally when switching from fresh to recirc and vice versa, you can hear the intake airflow noise change.

So, there was no way to get fresh air in when the temperature (outside) was high. I didn't have time to determine at what temp permitted the air con to allow fresh air into the vehicle. Later that night when the outside temp read 25 degrees, the fresh/recirc function worked fine.

Has anyone else noticed this in a D2 with climate control?
