    50/50 haldex mod

    I'm just posting a link to another forum where the use of a simple bolt with a pin in it can make your Quattro 50:50 drive.

    im very sceptical about it and can see premature Haldex failure but might be of interest to someone or point of discussion

    No centre diff will be an issue... haldex is designed to 'slip' to counter this (unless in a straight line of course)

    All it essentially does is lock the valve in the position where the haldex clutch is fully engaged... not sure but suspect the various control modules may have something to complain about... lol

    Not something I would want to use on the road as a daily tbh

    couldnt you just fit a 17mm bolt for less than £120+
    Word!!!

    My A3/Martys Golf would smash that, and this guys £7000 GT9743 supercharged love machine.

    Depending on the length of the pin at the end of the bolt, this mod actually might work in conjunction with the haldex electronics.

    My understanding is that the new bolt is going to relocate the valve a little deeper inside the oil gallery. This would cause the oil gallery to be closed off completely when the stepper motor moves the valve, giving you 50/50. On the other hand, I don't think the haldex will completely disengage as the valve would be restricting the oil flow. So you could be using anything from a 99/1 split to a 51/49 split when cruising.

    haldex info 2.jpg

    If the bolt is very long and keeps the haldex 50/50 at all times, then you can say bye bye haldex

    50/50 constant.
    think the clutch in the haldex would wear super fast and i bet they aint cheap to replace

    Give me a old Haldex controller and i'm 100% sure i could make a adjustable one rather than a bolt like that for the same price as the above one

    What's your approach to this Andrew? Same bolt style as advertised but adjustable or control the haldex ecu with a controller inside the car?

    Techincal question for any Haldex controller "experts"

    I got as far as controlling the motor, but think a servo motor would work better.

    Inbox cleared.


    Are You saying it will be adjustable from stock to permanant 50/50? So when in stock mode it will do its own thing??

    Or a case of 100/0 to 50/50 fixed?

    i just see that bolt damaging the standard controller.

    I brought the race controller (not the competition/blue)which is 50/50 all the time from the tt shop, this comes from haldex/borgwarner them selves, and i believe they uprate the piston in the controller as well as the software, for the higher pressure.

    just my 2p.

    Ive simply not had the time to get under the rear of the car to take mine off to give to andrew. Will do it as part of a fluid change.
    Getting the engine sorted has just been more of a priority with the little time i have.
