Thread: TDV6 2.7. Engine not start after fording

Hi Daz,

Yes I have found that one. Pulled it apart and can see no water ingress. Ecu was dusty dry apart from small stain at bottom....not near the circuit board. Can see no damage to board. Have purchase circuit board spray and sprayed board.

Plug near this behind battery was wet. Spray with water displacement spray and left to dry.

Put back together just now.

Engine fired up!! Hooray!

Left to idle. Alt light on...when getting warm oil light came on....switched off!

Checked faults....lots off.

Cleared and restarted. Oil light off, alt light off....still lights of faults. Alt light back on.

Have to park for now as time for work.

Guessing I have some plugs to pull apart and clean. Starting with alt plug.

Would appreciate advise on which other plugs/connectors to do.

Thanks all for help....hopefully seeing some light out of the woods....fingers crossed etc

Not rsttling or kn9cking.....was listening for engine problems to be ready to switch off. D8d restart and oil light wss off but only ran for 30 40 seconds. Then had to go to work. Hoping it is a watrr in pliug r cionnectiion tythrowing the lights on. Will retry tomorrow

Can I ask a favour chilly (or anyone who knows) - can you please write a list of all the sensors and connections that had water in them? I just bought a D3 and plan to waterproof as much of those as I can, starting with those more susceptible.

My apologies if this information is elsewhere on the forum.

Cheers

A good idea...but for after I have it fixed.
Prioritising on fixing first.due to this being a big concern....like all....cannot afford a dead car...or the potential of costs to fix...like new engine...or several ecu's etc....when I have destressed....then I'll try to put something together.

Home tonight and realised the car is blocking everyone getting their garbage emptying.....so....took the risk of starting and moving around the street on to my property.....all successfully done.

Alt light still on...so I'll look at this tomorrow. Will also look at connectors abovair compressor.

Will reset faults and sees what comes up and post on here.

Anyway of removing dash around inside fuse box...for ease of viewing etc.

O...will also check for any blown fuses.

Thanks for the support from the forum....very much appreciated at a time of dep concern for my loved Disco.

The connectors above the suspension compressor are water-proof and can't cause the errors that are occurring anyway. I would concentrate on the engine bay fuse panel which can be unbolted for drying access underneath - just don't stress the wiring unnecessarily.

Apart from the Transfer Case control module (which still maybe a fault, you dont know unless you get into electronics parts checking on the board, there nothing to say that one of the components hasnt failed on the board).

The other obvious D3 thing is the earth points.
*Inside cabin, bottom of A pillars, both sides, remove the plastic side kick panel as well as the flat panel that runs on the inside bottom of the door opening.
*You will find earth points on both side, undo, clean, tighten up.

*Also there is the harness plug, passenger side engine bay, between engine and the plastic battery compartment, i think its clipped onto the outside of the plastic compartment.

*On later D3's (after that first 2005/6 model) there are the main harness plugs on each side of the inner front wheel arch, you need to remove the inner guard plastic liner and you will see them towards the bottom of the firewall.

*There is also the harness plugs at the rear passenger side inner guard, can be accessed without removing inner liner, sits just behind the airbag, there is a vertical plastic panel that clips downwards, sometimes the clips break, but after when you fold it back up a large zip tie will hold it in place neatly.

*There is all the harness plugs at the back by the tail light assemblies, which who knows if thats giving issues, I wouldnt have thought so though.

Thats about all I can think of.....
