Thread: Water in Fuel Warning

Maybe water in the wiring loom that goes to the fuel filter?

Take it for a run and it will probably dry out,hopefully.

Thanks Scarry, wasn't sure I could still drive it, first diesel I've owned.

While it is likely to be just water in the wiring the engine is too valuable to assume that first off.

I would be draining the fuel filter via the drain to be on the safe side. Afterall that is what the sensor is for.

Not sure what year yours is but my 2010 D4 had that problem during rain in Albany. I went to the dealer and they said it was OK but to replace the sensor. I did that in Perth and found that the insulation on the wiring was damaged at the sensor. Seems that it is pretty poor insulation and breaks down giving a false water in fuel message when it gets wet in the rain or when washing it. Never had a problem with creek crossings, however, even at Cape York! Prior to the rain we had been through the creek crossing and mud hole on the track from Mutton Bird to Cosey Corner several times with no issues either.

Thanks Gary and Bob
Replaced the filter, no water at all.
plugged it in and came up with no engine faults but the water in fuel warning wouldn't clear so will be replacing the sensor. I think I will be a little more careful where I put the hose next time!
My D4 is a 2010 SE 3.0
