| Engine Valet damges gearbox unit |
|
We have just returned from Bots and I sent my vehicle in for a full valet. I was later called to be told that they cannot move my vehicle after spraying the engine with the usual high pressure gun.
Warnings on the dash were HDC, Brakes, and text warning of 'gearbox/traction fault'. I started the engine but there was no reverse or forward gear available. Zip, Trying to put the lever into park, resulted in a grating noise from the locking pin. I contacted LR and was advised to remove the battery and spray Q20 on the plugs & various modules situated there (supposedly in a closed box).
After some 3 hours of trying, LR sent a low bed vehicle to transport the LR to George. Here comes the surprise! 
I was informed that the Transfer Case Module was faulty due to water ingress. (I thought these modules are supposed to be in a sealed location!) and the cost would be R6,600 for the module! This excludes the labour, transport etc and it is not covered by warranty!!!
To date I have never opened up the battery box but LR installed the dual battery system prior to delivery. This means any problems in this area should be for their account or am I wrong?
Any info will help. I wonder what the MV Ombudsman will say. Ren Colyn

I'm sure I read it on this website or even in the owners handbook that you are not meant to use a high pressure hose in the engine bay 
Simple wading through water has nothing like the pressure a high pressure hose can inflict.

Valet company should foot the bill and they should also be well aware that high pressure hoses should not be used under the bonnet of most modern cars. I worked for Renault several years ago, and they would not even sanction a normal hose let alone a high pressure one. MY17 D5 1st Edition Namib Orange

It is not Land Rover's fault that the valet company used a high pressure water jet.
Why should LR pay?
Claim off the valet company or your insurance. Sorry. Renny Thomson

Hi Rencolyn,
Unfortunately, this is a well-known weakness with the D3, but is nothing to do with fitting the dual battery system.
The transfer case ECU is NOT in a sealed box, but behind the main battery box.
You may be able to recover by spraying the ECU and the connector with WD40.
It's unlikely that LR will accept the cost.
LR have repositioned the ECU in the aux battery box in the D4.
Good Luck,
Peter
PS: I know that this is a bit late, but NEVER use a high pressure spray in the engine compartment. The Bearded Dragon

If this is such a well know problem surely there is a solution by now. What is the feasibility of having the ECU sealed and waterproofed? If this is possible are there are cooling/heating issues to the ECU over time? Is it only moisture in the ECU which causes all the problems or are there other electronic modules or plugs/connectors which can cause these failures?

It is unlikely that the ECU would fail, isn't it? Surely it should be recoverable by drying it out and spraying with WD40 like bushwanderer said?

I know CaverD3 suggests also coating the ECU/plug in a sealant (Plasticote?).
I don't think that overheating is a problem.
Best Wishes,

I have not seen inside an ECU box so I should really not be commenting, but...... Water and electronics are mortal enemies. You might be lucky to save the ECU by drying the unit out and spraying with 'WD40' but IMHO I would think that would be more of an exception. I've managed to rescue some electronic boards (with discrete components)(not ECUs) by drying them out, but this is usually if found before power is applied to the board. The majority of boards with water on them will have blown components. As these ECUs in the LR are exposed to dusty and sandy conditions, when the moisture is added mud results and will sit under the electronic components and even if sprayed with WD40 could cause shorting of the pins of the ICs. With the new technology surface mounted electronic components the pins are so close together that shorting out is virtually guaranteed. If the unit is sealed or well protected from moisture then these ECU faults would not be occurring, correct?

Sure I paid under R2000.00 for mine replaced, 6 weeks back will look for the invoice and check. Certain it was the TCM they replaced.

Got the invoice out Description is "Fond corrosion in transfer box control module" code NNW512070 Replaced, "MODULE - TRANSFE" (Rest is cut off) R2261.44 seems it might be the same thing how come the difference in price? The invoice was dated 18/03/2010.

Dealer showed me a failed one yesterday, just circuit board in an aluminium box. You just straighten the tabs to remove the top cover.
I gave mine a good spray on the outside but having seen one I will open mine up and spray the board.
You will need to seal the boots that cover the connectors as well to prevent the connectors getting shorted with water. “There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely gamesâ€
