2016 RT electrical problem

[rrrocker]

Bike got wet under water for 2 days. (don't ask) Changed all fluids it starts runs good.

Fault codes: E11438 instrument panel: no CAN message status spring strut (from ESA)

E11436 KOMBI: no CAN message for vehicle access (from EWS)

CD9436 DME: CAN message (from electronic immobilizer) error

803EC1 GMS:under voltage

800FFD GM: under voltage

S 0332 No communication to the ESA.


Symptoms : Bike will start and runs fine.
Battery is fully charged at 12.8 volts engine not running.
engine running voltage is 14.4 measured at the battery and on the on board display.
there are no lights (head,tail,stop and turn) or horn.
nav will not turn on when attached to bike but works as should unattached.
radio and bluetooth work.
windshield will raise and lower using switch but will not park when ignition is switched off.
RDC shows — — on display.
When attaching battery there is a spark and the battery will be discharged the next morning. (seems to be getting worse)

warning lights that are on: ASC but may go off when ridden.
ON-board voltage critical ( yellow) even though the voltage is 14.4
Battery charge voltage insufficient(red) even though voltage is 14.4
Light failure (yellow) probably because of low voltage indication.
ESA fault

any thoughts?

Ok, I won’t ask, but I have to assume you mean the bike was submerged at least partially, in water. Seems like you have water inside some of the electrical connectors, but it’s hard to know which ones. Probably all of them, but the faults you observe now are just the ones that are presently acting up. Sooner or later more issues could arise. You’ve got to get the water out.

Remove all the Tupperware, seats, panniers, gas tank, fairings, etc. Disconnect ALL connectors one at a time and displace the water with an aerosol can of water displacing water fluid. I believe there’s a product that works better than WD40 but I can’t remember what it’s called.

You may just want to take the bike to a specialist who can do this work for you. It can get complicated and timely to restore to a dry condition. Once again, I’m assuming the bike was submerged, as you’re not to clear about what happened. Don’t start the bike until you KNOW the air intake box is dry. Hope this helps and good luck.

Thanks Frank, yes it was completely under. What is the "Tupperware"?

 

[kioolt]

I think your best bet is to let the insurance company total it.

Bike submerged

At the very least, all new sensors and complete wiring harness

 

[motodan]

In my world that would be totaled. Gremlins will pop up as more of system becomes oxidized by chemical/air reactions.

Welcome to the forum!
For some reason the outer "plastics" have been given the Tupperware nickname.
Anyway, I suspect that the water intrusion has developed some minor "cross talk" across the channels to the computer. The last time I was involved with this type of deal we put the machine in a closed room with a kerosene blower and baked it dry. I don't think the plastics on your bike will take heating with that procedure but a properly spaced electric heater should work.
Let us know how you make out.

This would be my vote.
I would not feel comfortable selling a bike that's been under water for two days.
There's a good chance you will need to mark your title as flood salvage.

Can you even sell a vehicle that was flooded? I know you can't up here.

You bring up a problem we have here in the US. If a vehicle is insured and flooded the insurance company winds up with the title and it is shown as a totalled vehicle. It is then crushed or sold off for parts. These usually are not resold as usable vehicles. But in many states half or more of the vehicles do not have insurance coverage for flood damage. In some states up to a third don't even have liability coverage even though it is required. In the case of uninsured cars owners drag them out of the water and do with them as they wish. Junk yards buy them for pennies or nickles on the dollar, dry them out, ship them out of state, and sell them with no disclosure that they had been wet.

Things like Carfax can be helpful but only that. For example, only a fool or extreme risk taker would buy a used car that was shown to be owned by somebody in the Houston, Texas vicinity in the summer of 2017 (Hurricane Harvey) , unless they could truly verify it wasn't a flood car.

Before the OP spends much time and money on the bike he needs to find out what the laws are in his state for selling the bike.

 

[omega man]

I didn't see where he wanted to sell the bike
Seemed like something goofy went on and he wanted to get it back running.....which he has. I'm pretty sure with a bit more messing around and riding the codes will disappear.

He did not mention selling it, but he needs to know what he's getting into down the road.

I bought a late model submerged vehicle once. The engine always ran fine but after about 3 months of ownership the electrical problems started and have never stopped to this day (7 years ago). SELL IT or total it if that is an option. It will never be the same. Trust me I know

 

[azgman]

or, bring it out to AZ in July and leave it in the sun for a day... no more water!

of course you may have rust or other particulates in the switch gear.

 

[kioolt]

Being under water for two days would probably let water get into the swing arm bearings and other drive line components.

I agree with what you and others have said in this thread.

OP,

Call the nearest BMW dealer and get their professional advice. YOU can’t fix this. It will never be right if it isn’t fixed correctly. Time for some soul searching; either try to have it fixed and continue riding or turn it in to insurance and tell them what happened and give them the dealership’s written prognosis. Sad story and I empathize with you.

I pity that ECU.

.

And the dash, ESA motors, and all those other electronics that are costly to replace.

Highway speeds in the rain? Pressure washers? I haven't seen a vehicle computer that wasn't completely sealed

Maybe the ECU is completely waterproof but I'm guessing there's a lot of things on the bike that can not take being under water for two days.
