Well I got a call back toady after the pump assembly was tested and it's f@cked. The pressure switch and accumulator are shagged and the motor itself is chewed out with the impeller chewing on the inner casing all due to the pressure switch sticking on.

So I'm getting a change over reconditioned assembly ex Japan for $1920 to my door from Hills Motorsport. The new pump is the late updated model with a better pump design and Pre filters fitted. Only catch is its a 30 day wait from Japan then for Hills to bech check and set it up then post to me, I'm expecting to wait about 6 weeks until I can refit it. Still could have been worse as its the last ready unit on the shelf.

I might have a spare assembly soon, not sure on the condition yet. That sounds like an expensive rebuild to me...

[slippylotion]

I wouldn't say its expensive seeing as the accumulator is around $350 trade price alone and about $200 for a pressure switch that you can't actually buy from Nissan then the cost of a new pump that again you can't buy separate from Nissan and I need the complete assembly. Nissan only sell the complete pump assembly for $5k trade. New pump assembly in Japan is around 200,000yen from Nissan. These are rebuilt in Japan but with Australian warranty from Hills Motorsport. Im not keen to take the chance on a s/hand pump as it could go a week later. Atleast with this I have a warranty and shouldn't have any further problems for the 5 ish years Ill keep the car.

[PN-Mad]

Ummm... RWD manual conversion? $2k would get you quite a way into the conversion I guess.

Hills motorsports...right.

Yep, I agree it would usually be the best option but at that price? Its not like everyone else is replacing them, they are quite reliable in most cases. It's you coin buddy...

[slippylotion]

Yeah I agree its a lot of coin but it seems the cheapest way to fix it correctly and completely. I though of a second hand unit but they sell for $700-900 so if it dies in a year or two its really half the cost of the fully rebuilt assembly wasted seeing as a new unit should last another 10 years or so.

Id probably guess that the other guys getting the pressure switch fault code or 4WD randomly coming on are probably in the same boat. I asked why my torque gauge would still read if the pumps shagged and he said its a theoretical reading via the G sensor not the actual pump pressure. While the gauge is showing front drive it may well not be actually getting it.

$700-900 for 2nd hand? massive rip off

i have a complete unit here you can have for $150. no idea if/what is wrong with it. but it might be a hell of a lot cheaper to pull bits off than 2k for a 'new' one

[slippylotion]

Thats cheap. Theres one on Yahoo at 25000 yen so far then postage and fees it will be around $400-500.

I know $1900 seems like a lot but I don't want to have another problem with it again while I have the car. I suppose its similar to replacing a turbo with a cheap stock unit, bound to go at anytime so might as well just go a new one.

I also just double checked the oil I bled out of it last week while flushing some through and found all the little metal fillings in it. Just a bummer all 3 parts of my pump assembly died

any more news on this one guys? i am wondering if my attessa has the same problem i have the same dashboard dimming and the front torque guage blip issue when the 4WD light is off.. when the 4WD light is on all is smooth.

though i think ill remove shafts and disable the pump rather than spend a heap of coin on fixing it..

[Sage222]

nothing?

[ironpaw]

nothing?

I had this issue...4WD light coming on intermittently, the ATTESSA pump chirping away...

I had a dead battery a month ago and replaced the battery, left the battery unplugged for a week.

Started driving again last Wed and haven't seen the 4WD light on yet...so not sure wtf the problem is...pump hasn't been chirping like mad either...

[Sage222]

wow that sounds like a cheap fix maybe ill give it a shot this weekend )

LOL you gonna disconnect the battery for a week?

TBH I think the problem will resurface after a few more weeks, maybe once the car is driven daily the strain on the ATTESSA system will probably cause it to come back...

[Sage222]

well i was thining more like the weekend than the week

i've just called Import Factory to see if they can read the TCU. They said they would get back to me.... lol.

[scotty nm35]

Kewish auto's in Dandenong have a reader, it picked up all my transmission codes, I think it was a Diagun unit?

[Sage222]

awesome thanks Scotty will hit them up if import factory dont come through. what did they sting you for a read? can they translate the codes for you? and one last thing if the light doesnt happen to be on will they still be able to get it?

[END SPAM QUESTIONS]

[scotty nm35]

They only checked it, and told me the codes, they were in english and self explanatory as I remember. Give them a call and ask, tell them Scott sent you down.

The tcu doesn't show the codes with a malfunction lamp, that is for the engine only I think.

[Sage222]

will do mate will try and visit next weekend thanks as always for your help!

[scotty nm35]

No worries, looks like I need to go back there myself, the gearbox isn't sounding good. Did I finally break it?
