I have a 1999 Discovery TD5 auto. A few years ago when we had some quite bad flooding I was taking some people home and went through some flood water about 2 feet deep and the engine just died. I managed to push it out to dry land and after a few minutes it restarted no problem. It's been fine ever since. We're having more flooding currently so I don't want to have this problem again. Can anyone suggest what happened and what I could do to prevent ti happening again. Many thanks in advance.
 
Two foot is about the max for D2 before water will come in through the doors. But even a completely standard D2 should be able to wade at this depth.

Take it nice and steady. Id use low range, second gear revs around 1500.

If you start flying about in any depth water your asking for trouble.

I do this kind of depth regularly with no problems at all.
 
Sounds more like water on the ECU if it started up as soon as it was dry ish without removing injectors/glow plugs and cranking over to force water out the block………

Would be smoking a lot too and sounding rough etc if he had flooded the engine ?

But yeah fit a snorkel if you're wading…….

500mm is max recomended depth without snorkal,
2 foot deep is 600mm, see where im going with this

500 mm is the hieght of the door seal. The air intake is closer to a meter high of the ground.

Apart from soaking the inside, a manual td5 disco will keep going utill water goes in the air intake or the ecu.

Anything over the 500 mm for an auto will comebinside the csr and fry the autobox ecu under the seat.

If I keep a steady wave I can wade to 2 foot without water coming in or cutting out.

Cheers.

obviously LR got it wrong and waisted all that development money,
 
car that stops in water and will then restart is usually water flung round the engine by crank pulley and belts.. shots out summit electrical ... after the engine heat has dried it out it restarts
on a petrol its probably the coil /dizzy/ plug leads.... or it was when i last had a petrol.

now it could be any of the underbonnet electrickery

if it was water down the air intake it wouldnt restart minutes later.

Think lr are quite conservative with it. Been bonnet deep in me v8 and that kept going. Also had it caughing after going too fast through six inches of water.

Im sure they more than aware of the type of person that was going to be driving the D2, and therefore set the wading depth to the lowest part of the door seal.

If you stop in anything more than 500 mm in a D2, you'll have a wer interior.

Cheers.
