    Traffic sign recognition - MIB3
    This will work for Australian models.
    Coding is by OBD11.
    You will need to open the bonnet for this to apply.

    To display the speed limit on the driver's display. This coding will use road sign detection mode not fusion mode. The front camera will only read speed limits not use any data with speed limits loaded within the maps.

    Click on Long coding
    Press the button on the top right that shows a '0' and '1' to see it Bytes mode; Each Byte has 8 bits (from 0 to 7 included)
    Press the right arrow down until you reach Byte 16
    Inside Byte 16 activate bit 4 and do not modify the rest
    Press the Validate button
    Exit Module A5 and enter Module 5F
    Click on Adaptation
    Search for Vehicle Menu Operation
    Enter menu_display_road_sign_identification and change to Active
    Enter menu_display_road_sign_identification_over_thresho ld_high and change to Active
    Press the Validate button
    Go back to Adaptation and look for Vehicle Function List BAP
    Enter traffic_sign_recognition_0x21 and change to Active
    Enter traffic_sign_recognition_0x21_msg_bus and change to ' Data Bus Infotainment'
    Exit Module 5F and enter Module 17
    Click on Long Coding
    Press the button on the top right that shows a '0' and '1' to see it Bytes mode; Each Byte has 8 bits (from 0 to 7 included)
    Down, press the right arrow until you reach Byte 5
    Inside Byte 5 activate bit 2 and do not modify the rest
    Press the Validate button
    A5-Driver Assistance
    Click on Adaptation
    Road sign detection fusion mode
    Change to "Road sign detection"
    Security Key: 20103
    Press the Validate button

    Restart the Infotainment by pressing and holding the power button between 10s to 15s and release.
    In the settings of the driving assistants, the option 'Dynamic Road Sign Display' should appear. Tick "Show in instrument cluster" and "Speed warning" to "Visual".
    There is also an option to warn when exceeding the speed.

    Note: You will now get a warning which indicates that signal recognition is limited. This warning will appear for a few seconds in the instrument cluster after you drive off. This message is only informative and does not produce any problem, error or failure. The recognition of signals will work normally but limited because it is not using the data from the maps.
    School zones at 40km/h will be detected as 40km regardless of the main speed limit and will show as a speed warning when you pass them.

    Be interesting to see if this will work in our Kamiq when it arrives.

    Is almost identical to what you do in a TIguan and Golf Mk7

    I have found that it is best to put the security code in first before coding or it wont let you do it (sometimes)
