    ABS Module - Understading PART #SW - GOLF GTI MK7.5

    Hello guys, as is known, VCDS doesn´t have the capability to deactive ´starting vibration´ in some 7.5 GTI´s.
    For those who don't know, starting vibration is the popular name for a torque limiter that VW has introduced on MQB platform to reduce wheel hop. On the street, it works like a traction control. The problem is that, even with the ASR and ESC turned off, the car cuts the power when the wheels spins, making literally impossible to accelerate in 1st / 2nd, even if it is stock. In my case, I have a Stage 2, pulling around 340 HP so this is also more unbearable.

    This problem started to be seen on 7.5 GTI´s with production date from May 18. On cars with production date before that, it is possible to deactive it without any problem.

    I´ve scanned two 7.5 GTI´s, one from April 18´ and other from October 18´. The ABS module part number is exactly the same, but I´m seeing differences in PART SW#. My idea is to replace my ABS unit to one from an older model to be able to deactive it. It is possible to change the PART SW #? How does PART SW# works or affects in this case? Is that causing the adaptation channel to be ´not avalaible´ , while in others car it shows the starting vibration setup?

    Best regards!

    You have to look on the differen SW Versions, which are in the next line, after the HW Version H62, which is both times the same.

    0400 vs 0973, so they changed a lot ....

    A downgrade of the software could be possible.
    For that you need the Flash File, that is available as download @ VW inside the one big Flashdata download, after registration @ https://erwin.volkswagen.de/erwin/showHome.do
    Than you need the VW Engeneering Tool odis e or a different tool that can flash, like VCP for example.
    No clue if this ABS is downgradable, that you have to find out yourself.
    But since the HW Version is the same, it should be.

    sorry can't help you with that, but sw 400 is not available via vw flashdaten, closest one is 412 so try FL_5Q0614517AN_0412.frf on your own responsibility and report back

    Resuming with this problem...
    I don´t want to play with my ABS module, so I would prefer to buy an used one and use it to make some tests.

    Why VW changes the SW? It could change the ABS behaviour for the system?
