Hi Dan,

I Have something similar happen when I park my Scirocco with dual flexalite
fans. What I guess happens is that as the car is running there is enough
cooling potential running trough the radiator, but when I park it and its
not moving then the switch triggers the fans to come on and cool the liquid
in the radiator. I always tought this to be normal.

Others may have a ore scientific explanation.
