    just pasting this here from another website as i have a feeling it may come handy for abs coding...

    MK100 ABS Coding | Ross-Tech Forums

    Retrofitting Adaptive Cruise Control to Mk7 (oh the fun you shall have!) | VW Vortex - Volkswagen Forum

    This is an extract from the link above:

    "There's a .pdf floating around out there by "Xagico" that lists a pile of different retrofits and mods that can be done on the Mk7; it has a lot of the coding changes to be made. So that's where I started.

    In ABS coding, however, the recommendations on Byte24 ( F4 or F8 ) were not accepted by my car. (I'm guessing this is because Xagico is Spanish(?), and the European cars came with some hardware as standard that were not offered on our cars).
    Anyway, using the Somnus's spreadsheet, I was able to calculate that Byte24 on my car should be either 16 or 18; I tried 16 there and it worked. Again, YMMV, so do the math for yourself.

    Next, I changed Byte26 to F0 - if you install the new rear wheel ABS sensors first and continue to drive your car without making any other changes, you'll probably have a pile of errors on your display. Change this byte and the errors should disappear literally as you're sitting there.
    (Xagico's pdf said to change this to 50, and when I had my just the wheel sensors in my car - without swapping the ABS module - "50" made the errors go away. But once the new module was in the car, while I didn't have any errors, ACC would not work. Helpful user at ross-tech forum suggested to try "F0"....and just like that, everything, ACC worked. Not sure how he arrived at F0, but I'm glad he did.

    Lastly in Byte29, Xagico said to change it to 39, but that didn't work for me. A user over at Ross-tech's forums helping me out suggested 22 - and that one worked."

    It's good to hear you got it sorted; I like to use the VCDS coding helper for these types of things and cross-check other cars' scan logs with the setup you are trying to match.

    Don't worry about any coding of the 5F unit, that's only for the menus to show up on the radio.


    With your component protection issue, you need to find someone who has access to ODIS, 5054a or vas6154 and access to geko; I know due to the right to repair stuff, some good VAG specialists have access to this now.


    There is a shady market of companies "renting" their accounts out in 15min\20min blocks, not going to recommend that here.

    @guile: hmmm........ the coding for the ABS module in your VCDS scan doesn't make sense (it doesn't comply with your words about the changes made).

    Here's a more elucidating form of the hex03 long-code string from your SCAN report:
    Byte
    Hex Binary
    00 01 00000001
    01 FA 11111010
    02 93 10010011
    03 A1 10100001
    04 54 01010100
    05 27 00100111
    06 29 00101001
    07 6C 01101100
    08 07 00000111
    09 7B 01111011
    10 06 00000110
    11 05 00000101
    12 41 01000001
    13 C5 11000101
    14
    69 01101001
    15 80 10000000
    16 C9 11001001
    17 2A 00101010
    18 94 10010100
    19 E0 11100000
    20 60 01100000
    21 82 10000010
    22
    96 10010110
    23 F7 11110111
    24 00 00000000
    25 42 01000010
    26 00 00000000
    27 B9 10111001
    28 C2 11000010
    29 09 00001001

    As you can see - the coding values that you describe are NOT consistent with the list above. Maybe these are the pre-change coding values? If so, please post up the actual SCAN results post changes (the old long-code isn't of much value if you are describing the coding values that worked!)

    Please don't PM to ask questions about coding, or vehicle repairs. The better place to deal with these matters is on-line, in the forum proper. That way you get the benefit of the expertise of the wider forum! Thank you.

    thanks mate and thanks for the reassurance regarding the 5F unit, i wondered if that would be the case. panic over...

    I've also managed to get it booked in with VW for component protection removal, lets hope i walk out of there without having to remortgage the house...

    thanks for the feedback Don, is there a reason Byte 14 and 22 are bold? the original coding didn't work as per the rejection photos i posted...

    I'm not sure if its linked to the fact that component protection has not been removed yet or if the coding is incorrect. I'm planning to try the revised coding as per the feedback below from another forum, Nuje on VW Vortex:

    "In ABS coding, however, the recommendations on Byte24 ( F4 or F8 ) were not accepted by my car. (I'm guessing this is because Xagico is Spanish(?), and the European cars came with some hardware as standard that were not offered on our cars).

    NO- my bolded Byte 14 and Byte 22 was not relevant to your purpose (which is why I didn't address these Bytes in my response). I simply wanted to confirm (to myself) that the sequence in these Bytes was consistent with the Ross-Tech coding spreadsheet - which says that Byte 22 is the mirror of Byte 14.

    But, since you have raised it, from my table:

    • Byte 22 = 10010110
    • Byte 14 = 01101001

    As you can see - the 2 x Bytes are indeed mirrored!!

    Again "NO". Component Protection errors do NOT affect coding values. As you have observed, modules with CP errors can have both their adaptation channel and long-code values changed without restriction! CP errors ostensibly limit the way that the modules operate-rather than how they are coded (and modules with CP can NOT correct Basic Setting errors)

    hmm...... without intending any offense to the original Vortex authors - I would caution against modifying Bytes based on a suggestion to change the entire hex value.

    To explain- as you will be aware, a Byte consists of 8 x Bits. It's important to acknowledge that each of these 8 x Bytes is independent - meaning that while a set of Bits might be associated with a particular function, each individual Bit is a separate (software) switch that has it's own singular purpose.

    The ABS module on your car has 30 x Bytes - so this module has 240 separate (software) switches in its long-code string.

    Here's an example of my concern about making whole-of-Byte changes as per the Vortex suggestion: Consider Byte 24 - According to the Ross-Tech spreadsheet, these are the Bit descriptors:

    Byte 24
    • Bit 0 = Restart when reversing
    • Bit 1-4 = ACC Setting
      • Bit 1~4 unchecked - Without ACC, Without Front Assist, Without AEB (PR. 8T0, 8T2)
      • Bit 4 checked - Without ACC, With Front Assist, With AEB (PR. 8T0, 8T2)
      • Bit 2 & 4 checked - With ACC, With Front Assist, With AEB (PR. 8T5/8T7)
      • Bit 1, 2 & 4 checked - With ACC (Follow to Stop), With Front Assist, With AEB (MK100IPB)
      • Bit 3 & 4 checked - With ACC (Stop & Go), With Front Assist, With AEB (MK100IPB)
    • Bit 5 = PLA3.0 Installed
    • Bit 6 = PLA3.0 related
    • Bit 7 = Trailer Assist Installed

    Assume for this example that ACC is retrofitted on a car that was factory installed with- PLA2.0 (i.e. NOT PLA3.0), No trailer, No ACC, No restart when reversing. The factory value on Byte 24 on this car would be 00000000=hex00. This is the same as on your car - see my previous table

    If you followed "the recommendations on Byte24 ( F4 or F8 )" from VW Vortex - the change would mean
    • Byte 24 = F8 =11111000, OR
    • Byte 24 = F4 =11110100

    Remember that Bit 0 is the right-most digit and Bit 7 is the left-most digit in a Binary number

    So in following the Vortex recommendation- not only are you telling the ABS module to enable ACC, the change also tells the module to start operating PL3.0 AND Trailer Assist!!

    Moral of my story (which of course you can entirely ignore) = when modifying Byte values after a retrofit - ALWAYS (capital letters for emphasis) make changes to individual Bits. Or said another way =NEVER change whole-of-Byte hexadecimal values!!!

    thanks again for the info Don, i'm pretty new to this level of coding so some of the info is taking a while to sink in...

    I'll use the somnus guide to revise Bit values when I'm back home next based on the hexadecimal table below...

    Decimal.....Hex digit.....Binary code
    0...................0...............0000
    1...................1...............0001
    2...................2...............0010
    3...................3...............0011
    4...................4...............0100
    5...................5...............0101
    6...................6...............0110
    7...................7...............0111
    8...................8...............1000
    9...................9...............1001
    10.................A...............1010
    11.................B...............1011
    12.................C...............1100
    13.................D...............1101
    14.................E...............1110
    15.................F................1111

    Based on the above conversion chart please confirm if your codes below are missing a zero at the end:

    "If you followed "the recommendations on Byte24 ( F4 or F8 )" from VW Vortex - the change would mean
    Byte 24 = F8 =1111100, OR
    Byte 24 = F4 =1111010"


    I'm just trying to make sure i understand this correctly...

    @guile: Ooops - my bad (good pick-up on your part)

    Yes, indeed - I failed to make the Binary equivalent an 8 x Bit number. (now fixed - thanks)

    As for your efforts to convert Hexadecimal to Binary (Hex2Bin) and vice-a-versa (Bin2Hex) - there are lots of websites that will do this automatically - like HERE
