If the amp is a L7 I can kind of see how that might be possible, since there is more communication than just audio.
By the way what is the issue?
The coding board setup can bypass some of this stuff as its
more basic in the way it works.
if you still have it maybe you could plug the L7 back in temporarily.
the factory head unit remains intact, was not touched and is operational. the original system was "individual audio".

I'm not sure what the engine malfunction is, BMW was advised to reinstall the software to help debug the problem.

although I still have the factory amp, the connections for it do not seem to exist anymore (musicarnw system, they also did the physical installation). emailed ken about this yesterday as well. guessing it'll have to get reconnected one way or another, so the software update can be done. haven't seen this sort of thing mentioned anywhere previously.
