2003 WJ 2.7CRD water contamination warning

Hi,

I recently filled up a near empty tank at my local Tesco, 62 litres worth in fact, within 3 miles a warning showed on the dash that I have found to be water in fuel contamination warning, I went back to Tesco and advised them and had them enter it on the daily log in case any further problems occur.

For the entire duration of this tank full the light has been appearing more and more frequently, I have now just finished that tank full and filled up elsewhere but the light for the moment is still coming on intermittently.

The car had a full service and all filters about 600 miles ago.

I am guessing there is probably a water bleed off but no idea how to do it, I know I have one injector which is weeping but not aware of any other problems with the vehicle, wondering if this is the fuel or fuel filter contamination, maybe they never changed the fuel filter as I told them too ?

Thanks - Based in the UK here FYI

Start at basics and works from there.... change all your filters once more and report back. GSF does a Mann kit that works every bit as good and is around 17 notes. It will tide you over until next time OR if it really must be genuine..contact Darren @

No need to replace filters.....although you could if it's old. There is a plastic drain off knob on the back of the fuel filter (the water sensor is plugged into the bottom of the filter). Just slowly unscrew it with engine ticking over and catch the water in a cup. Don't undo it too far or you will let air in and she will stall and you will have to prime the fuel system through the primer on top of engine....vacuum pump required. You can do it without the motor running but it for not come out so fast.

Given that I had a full service and filters less than 1k before this tank of fuel and subsequent warning light could it really be water in the system, water not from filling up with that tank of fuel ?

Will try the engine running bleed off tomorrow, any resources for this, not worked on this car since I owned it, the main reason I gave given up owning a Discovery, less things breaking every five seconds lol.

The only way water can really get in the fuel system is via the fuel tank so it sounds like there was water in that batch of fuel. But check the connector to the water sensor on the base of the filter....might be a bad plug to sensor contact causing the warning light.
