This fuel filter water sensor is a direct replacement for OEM part number WKW500080. It is a water detector mounted in the base of the diesel fuel filter assembly. It senses accumulated water separated from the diesel fuel and signals the engine management system to warn the driver when the filter needs draining, protecting the injection system from water ingress. Manufactured to OEM specifications, this sensor is designed for Land Rover Discovery 3, Discovery 4, and Range Rover Sport models equipped with Lion diesel engines. Note: this is a fuel system sensor, not a parking aid sensor.
