Also not sure if I should unplug the batteries for a couple minutes to clear out whatever bugs are lingering, this cars electronics make me worry about unplugging the battery.
I've done a lot of research on this. I've talked with a BMW service Foreman and no one can seem to tell me why but installing a rear diffuser disables the kick trunk function.

This is true for the bmw m Performance diffuser and other 3rd party diffusers.

All I can find out is that it happens but not why it how to prevent it from happening.

That's why I decided to wrap the gray part of the rear bumper instead of installing a diffuser. It looks really good (not quite as good as a nice diffuser) and the kick trunk function works.
