water sensor for feal filter


Recommended Posts


I have a water sensor WKW 000020, which can be placed on a diesel filter.

Unfortunately I have no schedule of the three connections and I can nowhere be found unfortunately.

The pins are marked 1,2,3 and assume that a + - and at a signal light should but what order.

Is there 12 volts on the signal wire?

I hope someone can help me.

For info : on the Disco 2 td5 that sensor is recognised as very unreliable& land rover even issued a service bulletin to suggest removing it if the vehicle dash water in fuel warning light operated excessively. Many td5 owners remove the sensor & tape the eiring connector out of the way.

I'll look up the connector wiring in a while if you really think you want touse it.
