View Full Version : BECM Flooded

Hi All. Story told on a Facebook group for prompt answers but the saga continues....

A while back, say a month I think, I put my P38 into what was a shallow water hole that turned soft sand and then diffed out. Straight away I went oh no, reverse back. Got about 20 cm and stuck again. Had a friend behind in his disco 2 and called out for help, but in not long water started trickling into the drivers side floor. Panic time. Window down and into the water I go. Took a while to get organised so before strapped up the horn and wipers start to go off. Yep knew what was happening here. Went back in to get the battery off but in all the panic things weren't going as hoped. Got it out after a few minutes of flooding. Thought the worst after reading many stories about the flooded BECM.

Took the car apart, disconnected all computers and started drying them out. Took the BECM apart and tried the best we could do in the bush. Put it all back together and all worked except the remote unlock didn't work. Figured that was OK. Drove out of the place and went up a slight hill and off went the horn and wipers again. Think the water in the rear ducting may have spilled over the BECM again. Decided to take it back to a hotel where out came the BECM again and dried it with the hair drier. Next morning I didn't expect great results but to my surprise everything but the remote unlock worked. Drove 45 minutes on tarmac, idled for half an hour, thought why not go and do the track we came up there for. Dove around for like 5 hours in the bush with no problems....

Then about 1km from coming out of the bush the car started losing power and came to a stop, almost like running out of fuel. Towed her home on a trailer behind the Disco.

Now lots of faults on the display. Gearbox Fault, EAS fault.... Fuse 7, Fuse 8 fault....

Thinking the BECM had its last moment. Nanacom won't connect. Everything is clean and dry.

No visible signs of component damage

So where to from here?

Any suggestions of places that can check BECM's out of the car, including the transmission and EAS computers? Don't really want to buy a BECM to find there is more problems than thought.

I'm assuming you need more than just a Nanocom Evo to sync the new BECM with the Engine ECU or immobilising reasons?

Maybe it could be just the power board although I have my doubts on this seeing there are lots of logic and connection errors.

If it's only the BECM then it's time to order one from the UK (not my daily drive). Expect $600 or so for one????

If it's more than that, then looks like it may be an insurance claim. Really don't wanna go through insurance due to the hassle of proving it was on a public road and I'm covered, the excess, record of a claim, having to recover all the mods and bits and pieces on it. PLan was to run this to the ground as a recreation vehicle. Insurance would be bound to write it off.

Place in Perth that looks to check and repair. Although I'd prefer Sydney based seeing I'm not certain its only the BECM. No idea of cost either.

Peter, sorry to hear the BECM didn't end up with the happy ending. Hopefully Rupert will be able to sort it out for you!

Unfortunately, yes those 3 computers also got flooded. Although I didn't have any faults from them after I recovered the becm/car until the car stopped after 6 hours of driving. So I'm hoping it's just the becm... I stress "hope", not "know".

I'll try and give you a call later today, if not latest of tomorrow.

Thanks, Peter

Just a thought.
After 5 hours the floor plan would have heated up enough to start steaming off the water in the carpet, and that invaded the becm.

They're more robust than I thought though; maybe a wash with some isopropyl alcohol might do it good also.

Yeh I thought it survived after it came back to life... I've cleaned it quite well in hope but it didn't help. Looks brand new almost. Anyone want an as new becm ha ha

Small update.

Well the BECM went to Rupert. Looks like he has sourced another late model BECM so will transfer my settings over to the replacement.

So if all goes well I will have the replacement BECM tomorrow for less money than I expected.

Happy days if nothing unexpected comes up in the reading of my settings.

If for some reason the other ECU's (Gearbox an transfer) are had it then they are cheap and easy to change. EAS computer worked with nanacom so pretty confident that is fine.

In future I am going to look for a wrecked late model P38 to cut it's becm looms off so I can make extender cables, using those plugs and my destroyed becm board mount sockets for the becm anyway. Thta a whole lot of cables though.

The other ecu's under the passenger seat look like I might be able to put them in sealed bags I hope.

And also look at ways to seal the door drain plugs up when off road as I suspect that is where it came in and then leaked inside the door skin/plastic sheet, or maybe where my aftermarket speakers sit.

A bit of tape over the drain holes works a treat. Just remember to take it off once you're home :angel:

Yeh I might carry tape thats adhesive works well under water. Got some aluminium tape that seems to stick well so might carry that from now on.

Well the becm is back in and all went well on first turn of the key.

So the Pete38 lives again and cost less than I thought, and cheaper than my excess.

Only error I have is low winds screen levels which I had before, airbag fault because the seats are out of it and disconnected, and sunroof fault but I don't have a sunroof (will disable with nanacom).

So hopefully all will be back together including the snorkel/airbox by next weekend.
