    По умолчанию Audi MIB2 Wiring diagrams

    Does someone have the connection diagrams for an Audi MIB2 main unit (quadlock) and control panel (2x10pin connector)?
    I would like to make cables to do benchtesting on a spare A6 4G MIB2 unit..

    Does someone know if the 8" MMI 3GP display (4G0919605) is compatible with the 8" MIB2 display (4G5919607) ?

    (Can i buy the old display to bench test a MIB unit ?)

    Hi Scrat,
    no the MMI Displays are not compatible to the MIB series. I use for both (MIB1 & MIB2) the Audi A3 Display Unit PN: 8V0 857 273 J for the whole Mudule with cabinet motor frame.
    The PN for the Display itself is 8V0 919 604 A.
    The reason is, that the MIB units using local CAN commands between main unit and display module.

    Thank you for your reply. So if i understand correctly the A3 display will work with an A6 MIB2 ?

    Yes it will work fine. I do all the MIB stuff on my desk with this display unit.

    It works with the VW Discover Pro and Skoda units too.

    MIB2 A6 display will work on:
    MIB1 A3
    MIB2 A6/A7
    MIB2 Delphi A4

    It will not work on
    MIB2 A4 Harman and i think all 8" HARMAN MIB2

    There should be a way to make it work though.

    Regards.

    I have just finished my wire loom to benchtest a spare mib2 unit. Thank you all for you help !

    However, after connecting screen, keypad and test unit and powering them up, not a lot happens

    is a gateway required to allow the screen tilt mechanism to open ?

    I've connected a serial terminal, but i'm not sure what is wrong with my unit...
    It looks like it is shutting down right after completing startup ?

    There is an internal CAN between Main unit, Panel and Display... do you wire it?
    The command to switch on comes via this CAN to the Display unit. Same as 8V0 (A3) units do...

    No need for gateway.
    Check the can communication between the main unit and kbd/display.
    If the can wires are reversed it will not work
    My unit did the same shutdown when i didn't had kbd and display connected.
    Worth checking the communication, plus the pin numbering in ELSA for the the back 12 pin connectors are wrong.
    In elsa they are
    1 2 3 4 5 6
    12 11 10 9 8 7

    But in reality they are
    1 2 3 4 5 6
    7 8 9 10 11 12

    Display and KBD can are 1,7 (they are the inner most pins)
    unit can is 6,12 (the outer most pins)

    Regards.

    Ah, so the left one is correct, and the right one is wrong ?
    I've wired it like in the right picture.

    I was just about to connect a scope and an analyzer to the display can bus wires

    For test just try Display can 1,7 (the inner most pins)
    You will have to rewire the KBD too.
    All MIB's use this wiring

    @congo: You were right.
    I've reversed the wire order and now the lights come on and the display flips open!

    The screen itself however still doesn't turn on.. I've tried switching display can high/low, but that doesn't help.

    I then suspected that the hsd fakra cable was wired differently from the other hsd cables, and
    I've made a new one based on the wiring diagrams, but that doesn't work either.
    Time for the analyzer.

    LVDS cable wiring diagram is correct in Elsa.
    just watch out for the numbering on of the pins..... i have them somewhere but have to look for.

    Found the problem.
    CAN analysis during startup showed that the display was not replying.
    I've removed the display cover to take a look and discovered that the seller sold me the wrong display (4G1919605, 3GP display) instead of the advertised mib model (4G5919607).

    Edit: For those who might find it useful, there IS a sticker with the model number, but it's on the inside.

    Oh crap, that's bad
    MMI display wont work with MIB, that's why you don't see anything on it
    Try to open a case if it's on eBay.

    Success ! Took me 4 purchases (and 3 paypal refunds) to get the right display, but now everything works.

    Hello Scrat,
    Do you have a wiring diagram to get a working MIB on bench?
