Drowned Disco 3 TDV6

[Paul R]

I have a 2007 Disco TDV6 project which I have been working on for a year. 10 days ago I finally got the car started after many attempts to solve a Can-Bus problem, then it became clear the starter motor solenoid was only working Intermittently so I took it out and bench tested proving solenoid stuffed and ordered a new one. Now for the question, I live in Port Macquarie and could not move the immobilised Disco. The flood came and inundated my disco up to just below the windows. I have stripped the insides and dried everything however I am constantly told it's stuffed and scrap it. Now with no insurance and it owing me about as much as it is worth ( as a going concern) can I get any advice as to wether it is worth the effort and cost to try to get this car going again, any experienced advice would be greatly appreciated . I will add I also have a 2005 Disco 3 TDV6 which goes very well and was not drowned.

Please help

If it was me i would be disconnecting all the electrical plugs you can find and dry/clean out with contact cleaner, i'm stubborn so i would persevere and try to resurrect it.
A good scan tool will help you find where the issues are so you can eliminate then one by one.

I have disconnect many connectors and cleaned and sprayed with contact cleaner. I have a GAP tool and been using often so no worries there. I tend to agree that at this stage having come so far its probably with the effort. Can't see any water in engine oil, only worry is ECUs inside the car I suppose.

You will want to remove and check all the modules, was the water up to the dash height inside ?

I would also remove all the ECUs and open them up to make sure they are not full of water and get a chance to fully dry out.

Sorry, to hear this, but don't power it up until it is all dried out as that might damage electronic parts, as tempting as it may be to try.

Probably disconnect the battery so that opening the doors won't wake up all the modules and damage something. Also, if things are wet with a battery in circuit might lead to electrolytic corrosion.

Good that engine oil is okay, so gearbox fluid is probably okay, not sure if diff breathers have a check valve to stop water ingress, and brake fluid is hygroscopic.

Hopefully the air compressor desiccant will have turned into a rock and stopped any water, but will have to be replaced.

I'd replace brake light switch as it can throw up a lot of faults under dry conditions, so I can only imagine if it's wet.

Personally I can’t see it ever being a reliable car, well were they ever but it will certainly be worse than a standard disco in reliability
there are very good reasons why insurance companies write off vehicles that have been flooded and a very good reason why they are classed as a non repairable write off at the auctions
personally I would bin most of it, a Disco with a blown engine is cheap as chips and you have the mechanical bits….

What have you got to lose by trying what has been suggested? The car would be almost worthless to sell. I'm like Nick and would have a go.
