| Air Con always on when Climate set to Auto
I have an 03 Cooper S with climate control.
When I select a temperature and click "Auto" button - the air conditioning light always comes on.
Even when its freezing outside and I've set the temperature at 20 degrees.
I always thought that the air-con was for cooling.
If this is correct then I'm assuming its to help stop the car windows from misting-up?
When the air-con button is activated, is the fuel consumption affected?
The fuel consumption is already worse than I expected - typically 26 mpg
