Hi, I have a cefiro, its also a leaky cefiro at the moment. Which living in Queensland you wouldnt expect to be a problem, but it is!

Where the water seems to be coming in is around the passenger side footwell. As thats pretty bloody close to the ECU Im a tad worried. That and every time I get in the car it smells. And the floor is wet etc etc.

It never seems to be a problem when washing the car just when it rains. But its difficult for me to find out if its from driving in the rain, or the car sitting parked in the rain.

So can anyone maybe shead some light on where I should be looking. Even if I can just put something in the hole for the time being to stop water getting in until I can get it fixed properly.

I did find what I thought to be one hole, and I filled that up (just a rag+plastic bag) but its not really working. Due to the position of the leak Im not overly keen to get the hose and go for my life on the chance it really wrecks something.

Think you know what it is post away. Also would I just go to a pannel beaters to get it fixed?

Thanks.

My first car had this problem.. an 85 VK Commodore.

Under the windscreen, kinda under the bonnet, you have a water-drainage thing on either side? It'd be under the wipers, but right on the side, and it's actually a hole in the inner front quarter panel.

If yes, then it's probably the same thing. That water drainage goes down under the car... problem is, it runs over (probably bare) metal, which rusted into a hole somewhere.

It used to fill up the passenger footwell to the point where I had to use a small bucket to bail the water out on winter mornings so I could drive to work.

Nothing else would appear wet... kickpanels off, ECU off, and still nothing wet. I think it was running down the firewall somewhere... but only ever did the footwell carpet get wet.

Frustrating, and looked like more money than the car was worth, so I never fixed it.

The idea I had for fixing this issue was to use a small PVC pipe, shove it down the drainage hole so that it goes from the entrance of the hole, all the way down to under the car where it normally drains out, and just to silicone the top of it. All the water would then get channeled down the pipe, and not touch the metal, and thusly not leak into the car.

If you don't have drainage holes where i've described, then i'm just typing for nothing! =-]

well what i am thinking is the bung for the ECU wiring is leaking

if it is then its an easy fix

jack the car up and place an axle stand under the car

pull the left hand front wheel off

pull the plastic gaurd off

locate the ECU wiring which is up towards the fire wall and look at the bung and make sure it is seated in the fire wall properly

if your not sure then grab a tube of skaflex and cover it up where the wiring goes into the bung and where the bung goes into the fire wall

Daveo I think I have this problem too!!

When I picked up the Ceffy.. I was like WTF! Water on Wolf 3D ECU! Not good lol.. Have had it under cover since so have'nt had to deal with it again.. May be in troubles next time I'm driving in the rain though. Maybe a fault with seals, dunno?

I think AgentR31 is onto something.. the guy that installed the Wolf is apparently dodgy, wouldn't be surprised if there was no gromet. Also my inner plastic guards are gone due to scraping

Sounds like a pain, but to get it properly....dash out :P

I know its a pain, but it may be the only way to see where its coming from / and fix it properly. If its a pin-hole leak, use sikaflex (black body sealer) or get someone handy with a mig to zap it.

It souldnt be too much hassle, if u just do 1 small bit at a time, and lay it all out.

Good luck.

ps - it aint the heater core is it? just when it rains?

cover the ecu for safteys sake for the time being.

Yep done and done.

I pulled the carpet back today, and I was changing wheels over so I had a good look.

It seems there is wear on the plastic tyre guard thing. So water could be getting through there. To me it doesnt look like the ecu gromit, looks ok. I dont have any sealent here so I'll try grab some durring the week and seal it up just to rule that out. But it does seem the water is getting in down where that is...

Im almost thinking it could be something air vent related as well.

Thanks for the help btw, anything else post it up.

Get the hose, and stick it into that water drainage thing I was talking about. Turn the hose on, and then see if there is any water coming in, while the carpet is stuck back.

The area you are talking about in the wheel arch is where the drainage that I was talking about should go.

    • Ok glad you clarified on the frenchy’s options , I was worried about if my oem hoses would fit the new compressor or not if I just bought the bracket/compressor kit ,  didn’t realize they also sold a larger full conversion kit. Hmm may just go oem in that case then to make it easy only because I plan to sell this car to upgrade to a 32 GTR or 34 GTT.
    • Right, here's a video of the basic operation at least.  This is what you can expect day to day when you turn the car on and it boots from standby.  The only thing from a media point of view I haven't gotten working is for it to autoplay plexamp when it turns on from standby (it works from cold boot) but that's more of a plexamp problem as it will autoplay other music players.  Also attached is my one stray cable.  It's part of the screen's wiring adapters but there's just nowhere for it to go in my car.  I've just now done a bit of research and found a matching port on a 2010-2014 head unit with BOSE.  Mine has no BOSE so that's that case pretty much closed I think.  Plugging in the Infiniti AC panel basically did nothing for me, so that's a dead end as well.  Next port of call is to mess with this CANBUS module and see what I can find from it.  I found this resource containing the DBC files for a 2010+ G37 : https://github.com/icecube45/Dash_InfinitiG37/blob/master/InfinitiG37.dbc I'll now have something to go from when I try to extract my CANBUS data so I can see if the HVAC Mode, Fan Speed, Temperature, etc. match and also the gear shifter position.  It's a pretty big assumption that it's just mismatched CAN signals but considering all the devices in the CAN network are talking to each other (AC can be fully adjusted just with no info on screen) it might be a safe one.  I will report back WhatsApp Video 2025-02-26 at 12.49.10.mp4
    • Thanks for that Paul.  Do you think if I posted a picture you'd be able to remember where it went? 
    • Sorry Duncan, I didn't get a notification for the replies.  Thanks for responding!  It's a full Android device, but does allow you to use CarPlay/AA as well.  This is the one I bought from NaviRS on AliExpress: https://www.aliexpress.com/item/1005006368602668.html?spm=a2g0o.order_list.order_list_main.111.59aa1802JDzQ0E - the 2K 8G-256G CAM variant but it seems to have gone up by £170 since I bought it!  My purchase was £307.14.   It's not the fastest thing in the world but performs perfectly adequately.  It stays on standby unless I disconnect the battery and let it power down, then it's just a fairly standard Android bootup time from cold.  The DSP Equaliser is very nice and made the standard stereo system sound pretty decent compared to the stock screen.  Perhaps I can take a video of it when I get a sec. It *allegedly* supports the reverse camera, but I'm yet to get that working.  It has options for reverse cam (a camera unit can be bought separately) or 360 cameras (also bought separately).  To be fair it doesn't seem to detect that the shifter was put into reverse but I'm working on a theory about this as well.  At the moment I'm going without which is a bit annoying considering the car is an absolute canal barge but so far I haven't caused any damage I'll grab a picture of the wire I'm missing later today when I can get outside.  My theory, by the by, is that not only is the head unit different, but the CANBUS network has different signals for the different years.  I think this because I have a spare AC panel from a newer Infiniti G37 (as opposed to my Nissan panel) which wouldn't control anything except the volume when I had it wired up with the stock system.  I'm going to throw it back in and see if the screen will respond to it.  I've just ordered an arduino CANBUS module so I can have a look at the signals going around the car and see if I can spot anything.  I'm thinking if I can work out what it's expecting vs what it's getting I might be able to translate and relay the signal back but so far just a theory anyway. I also found this on my travels, so far the only one that specifically matches my car: https://www.aliexpress.com/item/1005002822934280.html?spm=a2g0s.imconversation.0.0.33433e5fgttovi If you look at the picture of the before, it has the card reader slot, and the picture of the head unit is exactly the same as the one pictured in my original post.  I asked if they sell the cables separately but sadly they won't.  I didn't want to just buy this one because it's a super old Android version and only dual core - likely slow as hell. 
    • As above, you did refill the coolant and burp the system before running it again didn't you?
