    I tried these, none of them allowed me to change the auto hold functionality channel

    I've started something here haven't I

    Gizmo - was that the full list of ABS codes I gave you?

    I noticed there were some coding options elsewhere to let the car know Auto Hold was installed - I'll have a look later this week

    I have posted threads in the past, looking for this same ABS code.
    I have tried all the same ones as you on a 2016 A3 8V. None of the codes work.
    However codes were obtained in the past, it doesn't seem that anyone has gotten any for this particular ABS adaptation channel.

    Hey Uwe, how do we get our hands on this code?!?!

    Ok, I have been looking at a friends MY2016 Golf GTD manual with ACC with auto hold, his auto hold function channel is also set to "inactive" so it looks like we are barking up the wrong tree.
    I have been comparing our ABS coding but there are 24 bits on his module turned on which my 2016 octavia DSG with ACC doesn't have turned on.
    hmmmmm.......

    It looks like my code is 1AZ....

    my car is 1AT and is not compatible with AAC, I had to change :

    control unit ABS , ESP / ABS sensors, switch to ACC.

    Ok, I have tried re-coding every bit that the golf has on that the Octavia doesn't and with the exception of byte 25 they are all "rejected out of range".
    Byte 25 will recode but has no affect.
    I then tried to copy the HEX for every byte in turn but that was also "31-coding out of range" with the exception of byte 25.

    I'm open to ideas????? Is there a security access code for re-coding?

    Xpower: I do admire your tenacity and dedication to solving this problem. I'm not sure that using the coding from your friend's GTD is a good way to proceed - if you wanted to use this approach, then I suspect that you will need a much greater number of reference vehicles (to eliminate differences in coding that result from of other features in the car)


    Anyway, here is some information from my database. The car is a mk7 GTI PP DSG (from Ireland) with J428 fitted (including in this case also with R242 fitted) - details of the ABS enclosed. Notice that notwithstanding that this car also has ACC (like your friends GTD), there are significant differences (and some similarities) in the two coding strings

    Not sure that my data will help in your crusade, but it might be of interest!

    Cheers
    Don
