engine and radiator cooling fans
 
anyone know what controls when the engine cooling fan comes on and off. I am assuming the radiator fans are controled by engine temp thru a relay. wonder if the engine cooling fan works similarly.

The cooling fans are controlled by the DME software; the settings cannot be changed.

Does the engine fan come on when you first start driving the car I swear mine runs for a minute or two when I first drive away from my house when it's cold?

My engine fan does come on at startup also.

Are you sure you are not hearing the secondary air system, which runs for a short time at startup?
