    Heldex/vagcom

    After speaking to my friend who is a vag trained spanner jockey, he can remember changing the settings of the haldex on a golf 4-motion through the vag com.
    My question is can this be done on the S3, and if so could someone please let me know what the adjustment code is, my friend says it should be a three didget code that allows you to get into the haldex settings, and then this will allow you to adjust when the haldex will kick in.
    any help will be greatfull.
    somebody out there should be able to know if this is possible.
    cheers.

    Sorry mate - don't think I explained that one properly. I've read somewhere that it can be changed between Sport and Race. It could be the Gen II performance haldex thinking about it.
    ***EDIT***
    It is the perfomance one you need to buy along with a cable.

    When you use your vag com or any other fault finding hardware you can get into some systems that will allow you to go to adaptations and then chagne them, Every one knows about changing the open/close on their cars i.e when you close the car with the remote you can get an audible beep with the indicators or not, this can be changed in a certain block you just need to know the right codes to do this.
    I think this will work with the HALDEX you just need the right codes/values to input and then the know how to work out the 5 diget code/value that you have to enter.
    The only problem is that I can not find any one with this Knowledge prehaps some one with a complete copy of EKTA, Wil have these base values that we can work with thus changing the way/time that the HALDEX cuts in or stays in.
    I think that I am right because I have seen these blocks that Im talking about on a fault finding machine, And in the block for the HALDEX (which is block 22 ) there is an adaptation block but I dont know the right codes to input.

    Tried them still nothing.
    Not giving up still think that there is a way to alter the HALDEX parameters

    Maybe some adaption can be done, but the haldex PP has an extra electronic pump to engage the clutch before there is a rotational difference in input/output shafts (ie 4wd without any slippage etc..). so the standard unit needing the rotational difference to 'pump' the clutch closed will only be 4wd at the same times as before when front spin etc...
