Thread: Td5 fuel filter water sensor

Yes it should have a plug

Better dont bother with it, let the filter with it's own plug and isolate well the sensor's wiring/plug to not touch earth, the sensor is too sensitive and just gives you unnecessary warnings, as long as you replace the filter at decent periods you dont need it, tha's why LR didnt even fit one to later modells, also it's connected on the pump supply fuse and it can go wrong to blow the fuse then you'll not know instantly why the engine is powerless or not running

in a nutshell: IMO it's useless

Damn, I just bought one, and the plug on the wiring loom is full of dirt!!
Ah well, I might put it on just to see the light on the dash at start up.
What fuse do I look at? in case it blows.

Thanks

Julian

The light on the dash would do the self test no matter if the sensor is there or not cos the self test for warnings is managed by the instrument pack, the involved fuse is F10 engine bay(same for fuel pump relay)

Not much use to you now, but my 2003 Td5 manual has the sensor fitted from the factory, but also the function of the dash light disabled. AFAIK the 2004 models didn't even have the sensor fitted.

Why do you say that rubbish when my 04 has one fitted from new and the light functions aswell

I'll be more specific now that I have checked, VIN numbers from 3A838204 did not have the water sensor fitted from the factory, according to Microcat. See screen shot.

My 07/03 compliance plate (VIN 3A810XXX) has the sensor, but the dash warning light is disabled.

I have seen a LR document somewhere on the internet that mentions this function being disabled and the the sensor being removed due to too many false activations. As yet I haven't found it.

EDIT:- Found a thread that also mentions it being disabled, still trying to find the LR doc.
