I cannot fathom out what the snowflake button does on the climate control panel of my ' 99 pre-facelift A4.
Having read a tech article on the AudiWorld forums I was led to believe that pressing this button (and so causing the snowflake logo to appear on the display) disengages the compressor?
This is the opposite to what I find when using the climate in my car; when the car is idling and climate is in auto mode pressing the snowflake button causes the load on the engine to audibly increase (with a very slight drop in revs) and the air gets faster/colder (that is when 'lo' temp is selected).
I have also found that in really wet weather the side windows of the car de-mist a lot quicker when in auto mode and the snowflake button pressed, to me this signifies the compressor is working and is de-humidifying the air inside the car.
Am I totally wrong or is the Audi World article incorrect?
