Porsche Cayenne: Error code: 16864/P0480 - "Radiator fan control 1, electrical error”
If the above defect is detected, it may be related to a defective radiator fan module. Only affects vehicles with two fan motors (dual fan module).
The cause here is contamination in the control unit, which leads to automatic switching on and off and unusually long running times for the electric fan motors.
According to the vehicle manufacturer, the complete dual fan module must be replaced. Charge and check the vehicle battery and replace it if necessary. Delete error memory entries.
