This used Audi Electric Radiator Cooling Fan Relay / Module (OEM 4B0959501) controls the radiator cooling fan's operation. Also called a cooling fan module, it switches the fan on and off based on engine temperature. A failing unit often causes the fan to run constantly or not at all, leading to potential overheating—especially in stop-and-go traffic. This genuine OEM part came from a donor Audi A6 or A6 Quattro with a 2.7L turbo or 2.8L naturally aspirated V6.
