Radiator Fan 6R0959455D for VW Polo/Audi A1/SEAT Ibiza/Skoda Fabia 2009-2022 1.0L-2.0L

Radiator fan 6R0959455D is the electronically controlled cooling fan used across the Volkswagen Polo V platform and its Audi A1, SEAT Ibiza and Skoda Fabia sisters, and it is supplied as a complete assembly with shroud, blade and the control module built into the motor housing. The module is what separates this fan from an older resistor type: the engine control unit sends a pulse width modulated signal to the module, and the module sets the speed steplessly instead of switching between two fixed speeds.

Because the speed is continuous, the first sign of trouble is usually not a dead fan but a fan that runs at full speed from cold. That happens when the module loses the signal and defaults to maximum, which the driver hears as a roar for the first minute after start up. A module that has failed internally gives the opposite: no fan at all, a rising gauge in traffic, and a stored fault code for the fan control circuit. The blade and the motor bearings are robust. The electronics in the housing are the weak point, especially when the drain tube below the battery tray is blocked and water drips onto the connector.

Check the three wires at the plug for corrosion before fitting a new unit, and check the large fuse in the engine bay box and the earth point on the left chassis leg. A fan that twitches when the plug is wiggled has a wiring fault, not a failed module, and no amount of new parts will cure it.

Fitting is straightforward. Remove the air intake duct for access, unplug the connector, undo the single Torx screw at the top right of the shroud, release the two lower clips and lift the assembly out of the radiator cradle. Lower the new unit in, make sure the rubber feet sit in the cradle, reconnect, then run the engine with the air conditioning on and confirm that the fan ramps up smoothly rather than stepping between two speeds.

Supplied as one complete assembly with module, blade and shroud. Twelve month warranty.
