    ACC Retrofit Advice Please for Golf MK7

    Hi all

    I’m covering a basic write up on another thread regarding mods to my Golf MK7 PP DSG, including this ACC retrofit. I’m going to tidy that thread up as I go to try and provide easy to follow steps for anyone else that wants to do the ACC retrofit…

    I’ve been doing hours or reading on this and I’m still not 100% sure I understand what I need to do so I thought I’d check with the experts if you wouldn’t mind reviewing the below and picking me up on anything I’ve misunderstood. A lot of threads had info from Don (thanks Don) and I acknowledge that some of his material is included below along with XaGiCo Dossier (link below)…

    Dropbox - XaGiCo DOSSIER VCDS VW GOLF MKVII 1.5.pdf - Simplify your life

    I haven’t organised component protection removal yet. I have called euro car electrics on the Sunny Coast 3 times but couldn’t get through (they charge $300); next stop is VW Newstead in Brisbane. I’m toying with the idea of buying the VNCI 6154A tool but I think it could end up being a waste of money if I don’t know how to use it. I do know you can buy single uses of ODIS but don’t really understand how that works. If anyone else has suggestions for component protection removal I’d appreciate it please…

    Parts that I have bought already:
    Front bumper centre grille with radar hole – 5G0853677D
    ACC radar plug and loom – 4F0972708
    MFSW steering wheel switches – 5G0959442N
    Bosch Long Range Radar (LRR) – 5Q0907541J

    My install sequence plan:
    1. Remove front bumper and drill existing bumper iron to mount the radar
    2. Mount the radar with less than 0.2 degrees angle and refit bumper with new grille
    2. Route the wiring loom around the inside of the engine bay to behind the battery
    3. Feed the loom through the grommet in the firewall to the passenger footwell
    4. Connect the positive for the ACC to the fuse box and negative to a ground stud
    5. Connect the CAN-Bus to the black TUIL connector as noted below:
    Or/Br -> CAN-Bus Extended Low -> Pin 3 on Radar
    Grey -> CAN-Bus Extended High -> Pin 2 on Radar
    6. Remove the existing steering wheel buttons and install the new ones
    7. Hope and pray that was all done correctly

    Now the fun part, coding:
    01 – Engine
    Set ACC with Front Assist ( PR-8T3, PR-8T8 )
    03 – ABS (coding for 29 bit) you need to edit bit 24:
    Set F8
    09 – Gateway
    Add 13 – Auto Dist. Reg on the installation list
    Under Adaptation change steering wheel type to ACC
    17 – Instrument
    On the cluster set all the ticks for Front Assist and Distance Regulation
    5F – Radio
    Set all the ticks for Front Assist, ACC and PreCrash
    A5 – Front Camera
    Set presence of ACC
    13 – Radar
    Set presence of ACC

    This where I get a bit confused due to the following:
    1. The security access code (20103) that XaGiCo dossier mentions; is that just to allow me to make changes.
    2. ABS - how do I “Set F8”. From XaGiCo dossier it’s a set of 0 and 1 that need to be changed. Also do I have to change anything on byte 26.
    3. CAN-Gateway - minor detail but is it 09 or 19 (I don’t have my car or VCDS with me at the moment)
    4. Radio - do I also need to tick all AWV options as per XaGiCo dossier
    5. Front Camera - my car doesn’t have a front camera as far as I know. Is this an issue.
    6. Radar - XaGiCo dossier talks about setting Front Assist Camera and Trailer Recognition. Is this necessary.
    7. XaGiCo dossier has a coding step involving the need for ODIS (Funktion_ACC). Is this necessary.

    Thanks in advance!

    Ok thanks, I wondered the same thing. I’ll try again next week…

    First - where did you buy the LRR - or more particularly, does it have the correct dataset for this car? Have you read THIS?

    Questions:
    1 -security code ONLY needed if you want to make changes to coding values on new hex13 module (only needed for some adaptation channels)
    2 -Assuming that this car has a MK100 ABS module (with a 30 x Byte long-code string) I think the change needs to be made to Byte 24 (not Byte 29). Change Bit 2=1 and Bit 4=1
    3 The address for the CAN Gateway is 19 (not 09)
    5 No, lots of earlier mk7s didn't have the front camera installed with ACC
    6 See response 5 about front camera - does this car have a trailer module (@ address hex69)?

    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 for the reply Don…

    I bought the LLR from a wreckers and yes I’ve read that web page. As far as I'm aware 5Q0907541J supersedes 5Q0907541G...

    I’m not home for a week so will need to confirm ABS model etc then. See below screenshot of coding from XaGiCo dossier...



    I doubt it has a trailer module as it has no towbar so I guess I just don't tick the Trailer Recognition box...

    Do you know what the ODIS coding of Funktion_ACC is for on XaGiCo dossier, as per the screenshot below...

    Yes, as confirmed in the first of your pictures, the correct modification to tell the ABS module that you have added the ACC module is on Byte 24 (not Byte 29).

    I'm not quite convinced about the value of either F4 (for manual), or F8 (for DSG) - but both XaGiCo and my link suggest these values, so go with it!!

    As for the second picture, I first need to explain numbering theory (a little) - my apology if you already know this stuff.

    A Byte consists of 8 x Bits. Each Bit is independent of the other Bits. I think of a Bit as a software switch meaning that a Bit can have one of two states- being either ON, or OFF (just like a normal mechanical switch) - or 1, or 0. However, unlike a normal switch, the status of a Bit is changed by a software command rather than a mechanical lever, or button

    By convention, the Bits are numbered 0, 1, 2..........7 and the complete string of 8 x Bits make-up a Binary number. It's possible to convert Binary numbers into equivalent values in other counting systems. For example, there is an equivalence of a Binary number in the normal decimal system of counting and there is also an equivalence in hexadecimal (hex) numbers - which use a base 16 counting system. The values in XaGiCo pictures, F4 and F8 are hexadecimal numbers

    Again by convention, the Bits in a Binary number are read from right-to-left - meaning that the right-most digit is Bit 0 and the left-most digit is Bit 7.

    Here's an example: the hexadecimal number F4 is equal to the Binary number 1111 0100. So the last digit on the right in the Binary number is Bit 0 (which is equal to 0) and the left most digit is Bit 7 (which is equal to 1)

    Hopefully you are still following!

    In the second picture, Byte 26 =hex50=0101 0000. So, the instructions suggest that Bit 6=1 and Bit 4=1. According to my information, this means that you are telling the ABS module that the car is fitted with Bi-Directional Wheel Speed Sensors (Multi-Link Rear Suspension). ACC needs these type of speed sensors to operate correctly - I'm not sure what happens if you tell-porkies to the ABS module about this matter!




    I'm not a user of VAS5054 - but my guess is that the screenshot shows how to use the "guided-function" feature to implement the coding changes. The "guided function" facility is the forerunner of a similar feature that was copied by OBDeleven in their One Click Apps - it's an inbuilt software function that automatically implements all coding changes across each module without the need for the individual steps when using VCDS, or OBD11

    So the screenshot shows an alternative way of implementing the ACC coding changes - it doesn't show an additional coding change that's needed in the retrofit exercise!

    Great, thanks again Don…

    I think I’ve got enough info to give the coding a go now…

    The final piece of the puzzle is to get cp removed…

    If you take the car to a dealer, removing CP should cost the minimum time for a master-tech - which is normally 1 x hour. It shouldn't take anywhere near 60 minutes for a half-competent master-tech - but dealers don't use clocks to measure chargeable time -instead they use the monopoly principle of squeezing the client's wallet!!

    The last time a friend threw money at a dealer to remove CP, it cost $250- outrageous!!

    I managed to get time to fit the parts on the weekend and have a crack at the coding...

    some of the codes were not accepted which is a bit concerning but i'm hoping that can be rectified once the component protection is removed...







    one of the control modules couldn't be reached, 5F: Information Electr. I'm guessing thats because i've replaced the head unit with an Android one. Hope this won't be a problem when trying to finalise the coding...
