Hello! I searched on the forum and did not find anything similar to my problem! So i drove my GTR with my friends an launched it once, after that the car was fine and i continued to drive with no problems! We stopped after 15 minutes, and my car was parked for about 30 minutes, i noticed some brown oilsplashs on my driverside and a little bit in the wheelhousing! I checked for leaks on my brakelines but nothing there! After driving it again the car was handling really strange, everytime my 4x4 kicked in my car started to pull hard left, if i was just coasting and accelerating mildly the car was going straight! Now my question is did i break my front diff or could there be anything else that causes this problem. My allignment is a bit off but that pulls me to the right so i know it has nothing to do with that! Hope someone can help me! Thank you! Kind Reagrds

Hi, my 4wd in my stagea doesn't want to work with or without the 50/50 button pressed, sometimes there is both the 4wd and abs lamp on but I don't know how to check the codes, where does the ecu even sit? But the 4wd doesn't work even when the light isn't on when I spin the front wheel the axel to the gearbox does rotate, the oil for the attesa is there. I don't really know how to check if the pump is working or not. Help would me appreciated thanks

Hey guys, when full locking my r32 gtr shutters like crazy as if it has a locked diff. It has fresh oil and I've also put in an additive to stop the clutches from sticking. I'm not sure if it could be because of my other problem with my awd, which I wrote up in another post > -
I have just recently purchased my first GT-R (an R32) and was wanting to know if the way the front torque gauge is behaving is normal, abnormal, or whether the gauge is just abit dicky (like many a skyline gauge) So with normal driving my gauge sits anywhere from 0-10%, like i'm driving on the freeway at 100km/h i look down and the gauge is sitting on 10 (or 8 or whatever) and it seems to stay at that position until i completely release the throttle which (after a second) causes the gauge to drop back to zero. yesterday i tested the 4wd (as i didn't actually know whether it was working) so on a wet road i did a couple of moderate launches, gauge shot up to somewhere around the 40 mark and i got bugger all wheelspin so i presume it is working. also experimented with the 4wd controller which definately was working as on zero the rear was more twitchy and on around 7 it felt really good and could really put the power down on corner exit So does all this sound fairly normal? i was expecting gauge to pretty much read zero in all normal driving conditions and only show anything when giving it some stick. Thanks -
I have known for a long time that my 4wd doesn't work. with the ignition on and trying to do the attesa bleeding procedure my pump will not ever come on. i have 2 issues i believe, firstly, my pump has siezed up and i know this because i have bypassed the big relay in the boot and can not get the pump to start even whacking it the same way that frees up a fuel pump usually whilst bypassing the relay and giving the pump power. but i believe it has siezed because the ecu is not ever closing the relay. i have tested the relay on the battery and it is very noisy when it clicks closed. i can not hear the relay click closed when the ignition is turned to on which i have heard many other r32 gtr 4wd systems prime the pump every ignition cycle. i'm not getting any codes unless i induce a fault like unplugging the pump or a relay, so my ecu believes all is well and my front torque guage is operating correctly. my theory, my attesa ecu or wiring loom is stuffed and therefore the relay never closes and my pump is never getting used and that's why it has siezed up. any opinions would help. i should try another ecu and see if it closes the terminals on the relay and when all else is working well i should replace the pump, right?

FS. 4WD Attesa accumulator cannister. bought new in Aug 2012, didnt fix problem (new attesa pump needed), uninstalled after 2 days, nissan wouldnt refund. Basically new except for a few installation marks. These usually last around 10 years before internal charge is lost and 99% of time will fix the 4wd relay clicking on GTR / GTS4 and Stageas. Nissan retail these at around $350 Pick up from 4053 QLD for $190 or $200 posted. -
R33 / R34 non-vspec GTR Attesa Pump As above, willing to pay shipping. Must be non-vspec.

R32 Attesa Problem Hello! I know there are a lot of attesa posts here but i never found something for my problem (correct me if im wrong). On my car the 4x4 and the abs light is on, so i checked the attesa fluid in my trunk and it was way under the minimum and i thought that may be the problem! So i refilled it with an oil with the same caracteristics as NISSAN MATIC D. Then i opened the bleed nipple in front to bleed the system unplugging the plug behind the drivers kick panel. Doing that i hear the relais in the trunk clicking five times but nothing else happens! So i tried shorting the red and the yellow cable on the relais and the pump starts priming but no oil comes out the bleeding nipple. I then bought a new battery and tried with that. The first time i started the car with the bleeding nipple open the pump started priming and oil came out. I switched the car off and closed the bleeding nipple and retried but nothing happened and the 4x4 and abs light was still on. Since i had to close the bleeding nipple while the oil was coming i thougt now there may be air in the system. Now i retried starting the car but again the pump was not priming and again shorting the relais makes the pump prime but nothing comes. The pump even sounds like its priming without oil but the resevoir is filled. I hope someone can help me and sorry if i made any mistakes!

Attesa not working I have a S1 C34 that is manual converted, with power fc. I have the secret squirrel mod done. It previously had an extreme TSC that I removed thinking that may be the cause, but no change. My AWD has never worked since I bought the car 2 years ago. When I purchased the car the owner said the Attesa needed to be bled since the gearbox had been out. I bled the Attesa and it still doesn't work. I can hear the pump prime when I turn ign on and it runs occasionally while sitting at idle. I have had the awd and abs lights come on and stay on after sitting idle for long periods. I don't seem to have any fault codes to try and work out why it doesn't work. I have checked that the Attesa ECU is receiving a TPS signal and that is all ok. I'd really like to get it working, as it is hard getting the power down just through the rear wheels. I've been reading and am thinking either pressure switch or accumulator. Is there any way to check these for sure?

R33 Attesa Troubleshooting When putting my R33 gts4 on the dyno I've discovered that the 4WD is not working. It might have actually been broken for awhile, it would explain my poor 60ft times when I was drag racing last year (a month before I had the engine rebuilt). However in general driving I've only ever seen 4WD become active twice in the 7 years I've owned the car - I don't drive it hard on the street. That said the 4WD light wasn't on and I know it worked because when I had an ABS sensor go it did light up. I've now switched out my gtr ecu for a Link G4+ and a dash2pro so I don't know how to fault find on the attesa system anymore - does anyone have any ideas?

R32 Gtr Has Constant AWD Hi guys, 4WD light is on but my car is constantly awd, I pulled out both awd fuses and it was still sending power to the front wheels, (I had the car on a hoist). I have found that the awd bleeder connector in the driver side kick panel is there but there is no plug or wires coming from the boot into it. There is also a small loom cut before the pump in the boot. I noticed when the car was on the hoist on the front right wheel was spinning the same speed as the rears but the front left was stopped. Also when I took the car around the shop it would shutter when turning and if you accelerated a little and backed off it would clunk harshly. Any ideas?

Hi SAU, So I was replacing the old center console coin tray with a new cup holder/tray in my BCNR33, when I came across this device wired into the ATTESA g-sensor. Anyone know what it is/does? The wires connected to a fog light switch, I don't have fog lights. There's also a hole in the switch for an orange LED (not pictured). This LED would always blink whenever the car would start (not sure if pictured) then would turn of after a while (<2mins). The previous owner said it could be a 4wd controller, though he said he never touched it. I touched it of course, did absolutely nothing (nothing I could discern anyway). Last picture attached isn't mine, but it's what the three wires and orange LED connected to. The small black box I'm holding in the first pic has rotatable knob labeled fuse otherwise it had no other features or labels on it. It was connected to the sensor and to the fog light. I cant remember if it was connected to anything else. -
Hi guys, I took my gearbox off (R33 GTR) the other day and I made a mistake. instead of simply removing the pipe at the end of the gearbox, I removed the whole Flansh (Unit) where the pipe is attached to. Now my question is: Is it fatal? and there was a lot fluid coming out which I assume was the Transfercase fluid. Is that correct? So if I assemble it again can I simply reseal the unit and fill the transfer case and bleed it or was the fluid a different one than the on out of the transfer case? Is there anything else I need to take care of? Best regards!

4wd isn't working and so trying to diagnose. Tried to bleed the system yesterday but after disconnecting the green/white plug (pic attached), The pump didn't run and i could take the bleed valve completely out of the transfer case. Someone suggested getting access to the Attesa ECU and reading the faults from that via flashing LED. I got to the ecu but i couldn't see any blinking lights or anywhere that could blink? (pictures attached) Am i missing something here? -
I've got a 98' Series 2 Stagea and the 4wd doesn't work (See more here: http://www.sau.com.au/forums/topic/463038-help-with-fault-finding-attesa-system-attesa-ecu-c34/#entry7685341) Just wondering how do i retrieve error codes relating to the 4wd system? I've got to the ABS/ESP computer (Also 4wd?) and a few forum posts reference a red flashing light through a hole or someone said it is on the PCB itself. I've pulled the cover off the computer and could not see a light anywhere (See photos attached). Is there another way to get the codes?

Had recently changed transfer fluid and bled attesa using Nissan matic D, also changed a cv boot on the front right shaft. Everything done to the manual. About 30 miles after this I Was driving down the motorway about 70mph Suddenly a bang/rattle from under the car, could feel vibration from the tunnel in the footwell. The torque gauge shot Up well past 50 and stayed there. Pulled in checked under the car nothing hanging out and no leaks. I’ve a switch wired for RWD flicked it and decided to drive home and have a look, the steering felt heavier and there was a very slight rattle from under the car. Jacked car up, shafts all seem ok. there was a thin green and yellow wire wrapped around the driveshaft. Also some Non OEM wires seem to have been ripped out of the power steering rack. Also spade connectors on them which were also pulled out. Have absolutely no idea what these are for. No 4wd warning lights and the torque gauge will quickly rise fall a bit then shoot Up past max when ignition is on. (See video) Any ideas ??? Guessing transfer box is f**ked ?
