Hello, I noticed in my relay box in the bonet area, that I'm missing Relay 2, which is fan control.

When the car gets to 108oC in traffic the radiators kick in, but is this relay i'm missing a relay for the radiator to turn all the time, and then kick into the other relay when it gets really hot?

I hear some audi's when they first start the radiator fans are spinning, so is mine meant to do the same to keep the engine temperature down?
