    Hey guys,

    Having some serious issues with my MMI 2G (Bose system) and would appreciate some advice in troubleshooting to get this fixed as know a number of people on here are pros in this -

    Issue:

    1) MMI Screen is completely blank, does not turn on.

    2) The MMI centre console buttons near the gear shifter don't light up/ do nothing, speakers/ radio aren't even turning on.

    3) Given the above, I cannot go through the standard MMI button reboot (holding setup, control knob and top right button).

    4) As MMI doesn't turn on I have no radio, bluetooth, no sat nav, no control over suspension height etc.

    Full VCDS scan as below:
