Fuel Filter Water Sensor for the TD5 fuel filter assembly, fitted to the Discovery 2 TD5.

This sensor is installed in the base of the fuel filter housing and detects the presence of water in the diesel fuel supply. When water accumulates above the sensor threshold, it triggers a warning indicator on the dashboard to alert the driver to drain the filter bowl.

Note: This sensor is specific to the Discovery 2 TD5 fuel filter assembly. It is not compatible with the Defender TD5 - for Defender 90/110/130 TD5 applications, use WKW000030.

Fitment Notes DISCOVERY 2 1998-2004 — Td5 diesel only; water-in-fuel sensor for fuel filter/sedimentor. NOT for Defender Td5 (use WKW000030).

Frequently asked questions

What does the WKW500070 fuel water sensor do?
The WKW500070 fuel water sensor fits in the base of the fuel filter housing on the Land Rover Discovery 2 Td5 and detects water in the diesel supply. When water builds up past the sensor threshold, it triggers a dashboard warning so the driver can drain the filter bowl.
What's the difference between this sensor and the Defender Td5 one?
The WKW500070 is specific to the Discovery 2 Td5 fuel filter assembly and does not fit the Defender Td5. For Defender 90, 110 and 130 Td5 applications, the correct water-in-fuel sensor is WKW000030. Match the sensor to your model to avoid a non-fitting part.
How do I confirm this sensor fits my vehicle?
This water sensor fits the Land Rover Discovery 2 (1998-2004) with the Td5 diesel engine only. It is not compatible with the Defender Td5. Confirm your vehicle is a Discovery 2 Td5 before ordering, as the housing and sensor differ between the two Td5 platforms.
What are the signs the fuel water sensor needs replacing?
A failing water-in-fuel sensor on the Discovery 2 Td5 typically shows as a warning light that stays on after draining the filter, or one that never illuminates. A faulty sensor can let water reach the injection system, so replacing it protects the Td5 fuel components.
