Thread: Replacement plug for TD5 fuel filter water sensor

Scott i have one here at work i can snip off a loom. You need to solder it on to your wiring though.

Is your D2a setup to actually use the water sensor?

When I first got mine (2003) I tried various things to prove the sensor was ok. Ended up finding a thread (On here I think) that said although the sensor was fitted the D2a was not setup to actually use it.

IMO that sensor is quite useless as long as you change the filter regularly, also is too sensitive and used to warn withouit real reason... better insulate well the wires against short circuit and get rid of it, the sensor is on the same fuse with the fuel pump and it can blow the fuse if it fails... i've seen cases when the pump was replaced with new one in vain due to this sensor cos normally that's the first reflex if the pump fuse blows also it's not mentioned anywhere that this sensor is connected to the same fuse, it's shown only in the warning lamp's diagram... i've learned that on the hard way.

Geez, and to think that people in Australia pay hundreds of dollars for a Waterwatch which has exactly the same sensor in it.
I reckon the more sensitive the better.
Mine has never gone off and I like it like that.

Kelvo, my car is a D2 2002 EU3, so the sensor will be active. BTW I change my filter with every oil change and my sensor is new as the old one was broken by an over enthusiast. I also use water dispersant in my diesel.

The later D2a had the water sensor light dissabled in the relevant ECU from the factory due to the gremlin that kept flashing the light when there never was water in the filter.

I would like to know the source of this info, as I have never seen any reference to it anywhere else and another poster on the thread says his light still flashes,( presumably on a D2A.)
Anyone with a D2A had their light come on?

It's possible that due to the common thing mentioned in the recall bulletin the harness to be affected and causing issues with the sensor's circuit to make it flicker, or short which will blow thw fuel pump fuse : LAND ROVER Discovery Series , Diesel TD5 Recall - Possibility that the- according to mentioned VIN's all D2as are affected

Sierrafery, your post refers to the problem of the fuel manifold chafing on the ABS sensor wire, which mine did, although in my case it appeared to be a height sensor wire as it was unused.

Mine obviously did not have the recall done as it was the convoluted outer that wore through my high pressure line, right where it turns to go along the chassis.
If the wires could rub through and short on each other that could cause light on.
I have done some study on this and it appears that the light should come on if the return voltage is > 1.8 volts, so the light should come on with the plug unplugged ( or it may need the black wire earthed also.)
When I have a spare day with nothing to do I may check it.
