Hi

After update MIB unit has no sound . Car is Audi A3 year 2013.
original was MHIG_EU_AU_S1542  with MU software  0383, Part No SW: 8V0 035 043 R, HW: 8V0 035 043
updated to   MHIG_EU_AU_K1555 with MU software  0415, Part No SW: 8V0 035 019 B, HW: 8V0 035 043
Component: MU-H-N-EU    H40 0415
Car has no external amplifier (ex Bose).
After activating engineering menu, if press radio sound start working, but after exit from engineering menu with reset
sound stops.All other functions work ok, backup Camera, navi, voice command, etc.
With VCDS no errors preset.

Strange change on Part number after update!
Codding remain unchanged after update!

Any help is welcome
Thank you

It is a HW problem,not a SW problem.

Thank you for your reply!

Can it be solved by soldering audio part?

Problem start just after firmware update!
And everytime i force enter in Red Engineering Mode, i can hear sound OK from Radio.

Is it possible that fix come from parametrization with ZDC container?

Resolder the amps!

You can try parametrization, its the least painful thing to do and MIBs are knows to need parametrization after updates... 

But if Duke says to resolder amps... I would be afraid that he is right...
