    A6 c6 optical bus diagnostic

    Hello, I have problem with my MMI system. I found many info about common problems. But no solution for now. My MMI sometimes work very slowly, sometimes sound gone, stuck or reloading. I check all modules for water damage, everything look fine. My navigation unit was draining the battery, so I take it out and make a loop. But I think it's not a problem, becouse it just can't "sleep". Vcds don't show any errors. But main thing I can't make optical bus diagnostic. It's shows all errors (electrical and optical) , even mmi working fine. And I can connect to all modules. Can it be damaged and problem?
    Thank and sorry for my English 🙂

    Please post an Auto-Scan for context. The C6 A6 had two quite different generations of MMI.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Getting help in this forum requires the use of a legitimate VCDS system.

    They are available directly from us:
    https://store.ross-tech.com/shop/cat/VCDS

    ... Or from any of our authorized resellers:

    Let us know if/when you gets one and we'll adjust your forum status.
