Hi all
I have had my 2003 disco for a month now and so far i am really happy with it. But the other day i crawled under the rear just to check the condition of the air bags ect and i found some wires that wernt attatched to anything. They are orange/green, white/red and black. I have searched through rave and the only thing i can find is the wiring for the water sensor in the fuel filter, but in rave its got white/purple instead ao white/red. So i had another look on the car and the filter doesnt have a sensor in the bottom, it has a black plug but there is nothing to plug electrics to, and nothing lights up on the dash it stays blank where the light should be.
Should a 2003 d2 have this sensor fitted ?
I also found another plug hanging by the fuel tank with 2 black wires in it, does anyone know what this one is for ? everything works and there are no faults showing or logged its completely clear.
Thanks
Mark

I am guessing that i am right in thinking that these wires i have hanging are for the switch then,? Its like a big black plastic nut thats in the bottom of the filter, when i remove this to replace with a switch will the system need bleeding or should it be ok ?
I cant think why it has been removed as its got a full dealer service history with all the recipts, so it must have been done there.
Thanks for your help

They play up for a past time and bring on the management light. It's common to have them missing

the only real problem I can foresee is that you have to be careful what fuel filter you buy as some don't have a plastic drain valve on the bottom to plug the hole.

That shouldnt be a problem i do my own repairs and servicing when i can and i have always used genuine filters,the filter was only changed 1 month ago when i bought the car so i was only going to change the switch at the moment. so next chance i get im`e off to buy a switch, will i have to bleed the fuel system after having the switch out?
