Water Detector senses water that has collected in the fuel filter within the fuel filtration assembly.

Diesel fuel carries water that the filter separates and holds in its base. When the accumulated water reaches the detector, it signals the engine management system to warn the driver that the filter needs draining, protecting the injection system from water ingress. For Lion turbo diesel applications.

Frequently asked questions

What does the Water Detector (WKW500080) do?
The Water Detector senses water collected in the diesel fuel filter and signals the engine management system to warn the driver to drain it. Diesel carries water that the filter separates and holds in its base, and the detector protects the injection system from water ingress.
Where is the water detector fitted?
It's fitted in the base of the fuel filter within the filtration assembly, where separated water collects. It's used on the Lion diesel engines in the Discovery 3, Discovery 4 and Range Rover Sport.
What are the signs the water detector or fuel filter needs attention?
A water-in-fuel warning on the dash is the usual sign water has built up in the filter and needs draining. A failed detector typically either triggers a persistent warning or fails to warn at all, which risks water reaching the injection system.
Which vehicles does the WKW500080 water detector fit?
It fits the Discovery 3 (2005-2009), Discovery 4 (2010-2016) and Range Rover Sport (2005-2013) with Lion V6 diesel engines. Fitment is tied to specific VIN ranges, so confirm your engine and VIN before ordering.
