    MMI 3G+ 5F control panel baud rate coding

    I'm retrofitting 3GP into my C6 A6. I've got the unit installed and CP removed, I'm trying to change the baud rate on the 5F unit, so I can use the existing control panel.

    Reading this blog http://mycarfreak.blogspot.co.uk/201...verwenden.html I'm trying to change my coding and select "Byte 14 Bit 5" my original coding is 01010101000281E90116031E0020000380000100 and I believe the new coding is 01010101000281E90116031E0020200380000100 but keep getting and out of range error message. Am I doing something wrong here with my coding?

    Pleas post an Auto-Scan so people can see exactly what's installed in this car and the systems' overall condition.

    Here is a full scan of the car.

    A little history, the car was MMI 2G and I retrofitted MMI 3G which has been working fine for the last 4 months, so I'm now upgrading to 3GP everything appears on screen but the control panel does not work, and from the blog above I need to change the baud rate to 9600 but it's not accepting the coding.

    I also found this thread, but after registering it just points me to the blog in my original post. http://www.digital-eliteboard.com/32...hruesten.html?


    Should add I can perform the reboot command using the control panel so it is working, but functions are limited.

    Hi B5NUT,

    How about setting byte 14 bit 5 to 1?

    mit VCDS Programmiergerät Byte 14 Bit 5 auf 1 setzt.
    So above here Link:- http://www.motor-talk.de/forum/mmi-b...65.html?page=1

    That's what I set and it's refusing the coding. The 5F module has an early firmware version, so I'm wondering if this function is only available in later versions.

    I have now connected up a 3G+ control panel so I know all my wiring is correct and it's working fine.

    I'm going to update the firmware in the next few days so will report back.

    What my thoughts were after reading the motor.de post was to try setting byte 14 bit 5 to a 1.

    Are you not getting a 2 there, comparison of your coding from post 1:-

    Byte 00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19
    Orig code 01 01 01 01 00 02 81 E9 01 16 03 1E 00 20 00 03 80 00 01 00
    Refused code 01 01 01 01 00 02 81 E9 01 16 03 1E 00 20 20 03 80 00 01 00

    Are you getting a 2 by setting byte/bit via tick box in long coding helper?

    Why not bypass the long Coding Helper entirely. Simply type in the required code directly into the "new coding" box and click Do it! (instead of relying on any part of the long Coding Helper)

    Thanks guy's but I've already tried all of the above and it simply will not accept any value other than 0 in second digit of byte 14, the first digit will accept 0,1,2,3 & 4 after that all other coding is refused. I'm sure it's down to the firmware.

    Solution! So still have the problem where the unit refuses the new coding in byte 14. So I purchased a 3G+ control panel that works with the faster baud rate.

    Once you have control of the MMI system you need to enable the hidden menu (info on this can be found here http://www.audi-resource.com/mmi3ghiddenmenu.php)

    Go into the hidden menu and select frontctrl



    Set both values to 9600 and reboot the system


    This was my coding before changing the baud rate
    01010101000281E90116031E0020200380000100
    This was after the change
    01010101000281E90116031E0020200380000100

    Nothing had changed in the coding, so this could be down to my firmware version as it is very old (2010) or it could be down to a specific model of MMI3G+ A4, Q7, A8 etc or a bug in the latest version of VCDS, I have no idea which, however I do know it works using the hidden menu option, problem with this is you have to have a 3P+ control panel to get into the hidden menu to change the setting.

    Point to note once you set these values, the 3G+ control panel no longer works, but at least your old 2G control panel will now work

    I know this is an old thread, but I wanted to add this for anyone who comes across it in the future.

    I was able to successfully reset my baud rate by setting byte 14 bit 5 to 1. Module info is below. The software version on the head unit is HN+_US_AU3G_K0814. (Note the coding string is from before I changed the baud rate)

    Code:
    VCDS Version: Release 17.1.3 (x64)
                    Address 5F: Information Electr.
    Control Module Part Number: 8R1 035 746 G
      Component and/or Version: H-BNT-NA      H42 0901
               Software Coding: 160200060005A1EF51028B5E00000403140000000000000000
                Work Shop Code: WSC 06335
                          VCID: BB3670813AF419997C-80EE
    Thanks to this, I'm able to run a 2008 S5 control panel with a 2014 3GP head unit on my test bench. The 'car' and 'tel' buttons are reversed, but it's good enough for bench testing.
