Chopchopsee - Can I suggest you take a look at the carpet around the passenger footwell and check if its damp - the quote I'm getting from Nissan to replace the BCM and PCM which been soaked in water, is;
£2,500 just for the parts !!!!!!!!!!!!
And its now been suggested that the wiring loom may need to be replaced, as the connectors have corroded. And they are quoting;
£5,500 for the wiring loom, plus labour !!!!!!!!!
At the moment I've got a very expensive skip with a GTR badge on the back.
If the terminals on the end of the plug silver they will be ok.
This is just a dealer going over the top as usual.
WD 40 sprayed on the connections and plugged in and out four or five times would clean the connections in seconds.
Might be a idea to source a second hand ECU. there was a place in wimbledon many tears ago used to refurb ECUs.
Hope this helps Goldie
The really, really, irritating thing about situations like these is that you have absolutely no way of telling whether the HPC disturbed the grommet when carrying out the work on your car. Add to that the fact that it's in a stupid position that appears to be almost directly above the where the BCM is mounted and you have to conclude it's absolutely nothing to do you with you. And yet you might still get slapped with an enormous bill at the end of this. Let's hope that doesn't happen.
I'm surprised that there's not been more noise about this on the UK forum before though. I would have thought that if the grommet was not doing its job (if left undisturbed) there would have been many more reported incidents of the same problem. Has your car had any previous work done that would have entailed additional wiring running through that grommet?
I guess all of us with early cars are now sat waiting for this to happen and will be bricking it every time we drive in the rain until we get round to caulking up the grommet.

Really feel for you - just checked mine before and after putting it through the car wash - luckily all seems dry - hope you manage to find a more cost effective solution - I would definitely suggest speaking to one of the independents like Sly at Kaizer as he is truly encyclopedic in his knowledge of all things GTR and a genuinely good man who will advise you honestly

If Nissan agree to foot the bill, no issue, as it appears to be a design fault. If you have run additional wires and they can dispute fault as it has been tampered with PM ME, DO NOT PAY THIS STUPID AMOUNT OF MONEY.
If they refuse, as GoldGTR35 rightly says, we can get the BCM unit out, strip and dry or spray with WD40.
Most electronic components and circuit boards these days have a laquer finish, as with most mobile phones, to prevent moisture corrosion.
From reading your post I am almost positive from the intermittent nature of the problem that drying/waterproofing will cure the issue.
If dirty water(Conductive) gets in it creats a short circuit, but once rinsed with clean water (non-conductive) and dryed most often everyting returns to normal.
DO NOT pay the stealers this rediculus amount of money.
PM me if you need help with getting this sorted. It can be done at a fraction of the cost I assure you.
I have now lodged a case with Nissan Customer Services to try and sort through warranty. Westway Oxford HPC have stated that Nissan will not entertain a warranty claim, as they dont believe there is a fault. They wont even send an inspector out to view the damage. Its slightly more complicated than initially reported, because Nissan are stating that because I have had the BDL front and rear camera kit installed, which has the flat cables going through the same grommet, this has caused the leak.
However, I have found and forwarded evidence from many people from Europe and the US who have had the same issue without any other cables being routed through the grommet. I have also forwarded the details for the AMS shield which has been developed because of the demand for a solution to the problem. I believe there are Nissan instructions to wire up the aftermarket Nissan DRL's passing cable through the grommet (in other words its the recommended route) and I'm looking for this in parallel.
Nissan have quoted over £12k to replace the main wiring harness, the short harness and potentially the BCM and PCM module if these needed replacing. I don't think they need replacing, but can't tell until they wire the car backup.
I have an alternative plan to resolve this, but its inappropriate for me to disclose until I have a final answer from Nissan. I have experience of resolving this kind of issue through legal means, but its not a route to undertake unless absolutely necessary.
Thank you;
The feedback from helpful individuals on this forum is immense. The supportive comments from people who have replied to this thread is really really appreciated - its pretty stressful to have spent a small fortune on a 2010 car 6 months ago, which still has another 6 months of Nissan warranty remaining and has only covered 11k miles, to be told that I should spend another £12k+ on fixing an issue not under warranty. And I'd only had the car back for 48 hours after spending £800 on a service.
Once I have a conclusion from Nissan, I will post photos, correspondance etc as I believe other GTR owners should be aware of the issue and should mitigate themselves.
BUT - If you have condensation in your car, if you have slightly damp carpets in the passenger footwell, if you have any other cables going through the grommet behind the battery other than the main wiring loom - seal the grommet yourself now. Its prone to leaking under heavy rain, as water trickles down the side of the wiring loom. Over time this will corrode connectors or worse.
And if you have any of these symptoms, please let me know - because it will help support my case in getting Nissan to fix under warranty!

W4RPED, as has been said in this thread, I'd take the HPCs assessment with a pinch of salt. If the BCM dries out and works, why on earth replace everything, that's just nuts and over egging the problem to get some big money work out of the warranty.
My feeling is that much of the warranty decision is based on Nissan trying to mitigate the expenses brought to them by their HPCs.
Either way, there is no way I'll let you spunk 12k on this.
I'm concerned about mine as i do sometimes seem to have excessive condensation in my car and have to sit with the blowers on for a few minutes before driving off.
Does anybody have a picture of this grommet and where to find it so i can check it out?
As ***** says, is there a guide on where to look? Do you have to take the battery out? Is the grommet completely sealable or are there looms running through. Will sealing it fix this issue?
Thanks. That is the whole point of a forum surely isn't it?:thumbsup:
Just look at what "Super Sanj" as I now call him and "Honda_Pilot" have done for other forum members.
We all have the same beast and we all benefit from the collective knowledge and some of the specalist knowledge that we have on here.
I absolutely HATE to see anyone get shafted. £12K my fu**in arse. My real worry is that if the car is left too long at the stealer, or played about with, it will require major work.
I am sure with CC's knowledge and the mechanic who tends the fleet of vehicles for the company I work for, this will be sorted for a fraction of the cost quoted.
I am happy to do what I can to assist, and have PM'D W4RPD with my number.
We will see if this can't get fixed at my kind of money.:thumbsup:
The easiest way to see it is to grab a torch, get on your hand and knees and look up behind the glove box from the passenger footwell. It's about 10-12 inches up and towards the exterior side of that footwell. The grommet on my car is about an inch wide.

Sam you can see it in the link posted early in this thread to the pop up bonnet canceller install guide. It's about 6 or 7 photos down into that thread once battery has been removed. That thread also gives good instructions on battery removal. Might have a crack at it this weekend and break out the duct tape and caulk. Or maybe I'll bottle it in case I mess something else up ...
I never sealed mine as the torrential water ingress only happened the once in horrendous conditions on the M6 years ago. The missus got wet feet but all else was okay.
If memory serves the metalwork around it is smooth but I can't remember how good access is from inside as it was ages ago when I was looking for an easy route into the cabin for a long forgotten project.
If access from inside is tricky, you'd have to remove the battery and access it from there, and that's a tight squeeze.
If it wasn't so bloody cold I'd nip out and take a ganzy but I'm staying inside where it's warm.....
