Attesa System

[Gts4RB30]

I have an r32 gts4 and have followed the tutorial on how to bleed the system albeit may be a shortened one not sure.

Couple of issues I've had are: Does the car need to be perfectly level?

Does the transfer case need to be full when bleeding the line?

When the pump engages is it loud or is it just a click sound and its pumping?

I have checked the pump out to see if its pumping by getting someone to connect and disconnect the airlock bleed connector in the foot panel and i can feel it clicking on and off but it's VERY quite in operation and it almost seems like its not pumping IE like a fuel pump. I'm just a little confused on the issue as i am a first time backyarder to this operation. also can it possibly be gravity bled?? and when people say that the fluid needs to be 30mm above this line then 5mm below that one and then your meant to have 5mm of clear space in the reservoir..........................WTF are they talking about wouldn't it just be maintain the fluid in the reservoir so that it doesn't run out????

Thanks in advance.

I just cant find the info i'm after anywhere.

The easiest way to bleed it is, run the car on the hoist with the bleed nipple cracked (make sure your ATTESA resevoir is full). The pump noise isnt too loud at all. Make sure you have a nice steady stream of fluid coming out the nipple and make sure all wheels are turning on the hoist. Hope that helps

Attessa is a mystery to most. Theoretically if you can find the Attessa ECU (on a Stagea its in the boot wall LHS on a Skyline it may be under the parcel shelf) there is a light which can be made to produce fault codes. The British GTR site has a few articles on the Attessa.

BTW there are two bleeding nipples - the one at the back of the transfer case and another above the (rear) diff.
