Getting a pair of new Pirelli Scorpions fitted next Tuesday so the bank balance will take a bit of a dive
I think i will go for the full unit and use my existing filter canister as it's done less than 100 miles, the filter with the assembly I shall keep for the future. The Filter alone is around £20 (Genuine) so the carrier bracket and sensor will cost me around £65.
The other consideration is that, although relatively easy to get at, as posted, access is tight and at my age, not a job to regularly lying on my back with the car on ramps etc. plus the foregone conclusion that the bolts holding the bracket are bound to be rusted in !!

Always happy to help mate
Would u mind plse when u get the new filter assembly to see if there any names on the connectors along with taking another ohms reading plse
As u got 5 ohms on ur current one will be interesting to see what a new one is
Would be interesting to find out what lurks inside the connection box. I think it's more than just ordinary wiring connectors :ideaRelocated to Mid France from N. Wales March 2021

Hiya
Indeed, see it detects the different resistance between diesel and water , water having the lower resistance
When u do buy a new one if u don’t mind testing it plse, will be interesting to see what the ohms readings are on the new one in comparison
Will then at least know what readings should there
Ordered the repair kit as shown in your picture (Plastic housing & mini loom), should arrive next week.
Will update when I do the replacement....a job I'm not looking forward to doing Relocated to Mid France from N. Wales March 2021

Hi mate
That would be great please ref an update
Apologises as I couldn’t remember , did u say u had a gap iid plse
Update repair kit came today and I have had a look at it and have an idea what could cause the problems.
Attached to the underside of the cover is a spring steel wire which is connected to a short cable with an eyelet connector crimped on the end. This connector is secured by a Torx screw which holds the connector block to the cover. The spring wire is positioned where the unpainted top of the fuel filter sits and obviously makes electrical contact with it.
The connector block is encapsulated on the underside an as a result no internal components or connections can be seen. The sensor connector appears to have only one pin and the body harness connector has three wires; Black, Red with Black trace and Yellow with Black trace. The only resistance/continuity reading I could obtain was between the spring wire and the black pinout on the body harness connector which was around 10 Ohms, all other pinouts were open circuit.
My thoughts are that the spring wire is not connected to the filter element physically, maybe it has broken off or corroded etc.
Hope the pictures help

Hi
Many thks for the update
Could that piece of wire be there so if the fuel filter isn’t fitted it stops the fuel tank fuel pump from coming on ??
See as well with the Water sensor being fitted at the bottom seeing that water is heavier than diesel makes sense
Also haven’t got the same knowledge as u guys when it comes to this and to be honest never really looked into it
I blame u , lol, as I had to then look on some wiring diagrams and see the wire H1 goes back to the first sheet
Do always like to learn new things

EDIT
Discovered that the resistance reading between the spring wire and the black lead was caused by a bad connection between the wire itself and the eyelet connector on the end of the black fly lead-the groove where the spring is located on the top of the plastic housing was a little too deep. Rub over with a file to reduce the depth and all is now good, full continuity present with everything reassembled on the cover. Relocated to Mid France from N. Wales March 2021

Could just be that the spring wire is corroded, at either end, and is not making contact properly?Richard

That’s a great find mate
Assume a wire has to go back to the dashboard to illuminate the water in fuel warning lamp
Put my edit up before reading your post Gary.
Could well be that the Nerds at LR could use that input as an additional safety interlock with the in tank pump. Who knows unless there is access to the ECU code ???
Just had a thought (Again)!!
When I drained the sedimenter a couple of weeks ago, nothing came out of the open drain with the ignition in pos 2, nothing happened until I started the engine and it gushed out.
Raining here and forecast unsettled for the next couple of days so not getting underneath to fit it.
Another thought When I come to do it, I will scratch some paint off the filter body and check continuity between the body and the black wire on the body harness connector-if it's open circuit chances are that its a problem with the spring wire connection.

Have changed the fuel filter a couple of times and given the PITA job with access etc, never thought to look for anything like the wire-assumed that the sensor alone took care of it.
Only since getting the part today and looking at the beastie did it get my old grey matter working. I thought that the connector block looked a biy elaborate and when I removed it and found it encapsulated my thoughts were "There's more to this than meets the eye" Relocated to Mid France from N.
