My 2014 Z4 has the same fault code but my trunk is accessible. I tested the signal pins 7 and 10, both have 11+ voltage. I will test them again to make sure I didn't count the pin number wrong. If not I will test all the brown signal pins to see if any of them 0 voltage.
7 and 10 pins have voltage.
I am thinking to test rest of the signal brown pins at this point.

My multimeter did not show any continuity across the pins for the new micro switch, but when I checked ohms, it shows 0.5 kohm not pressed and 2.8 kohm while pressed. I assume the new switch is good. I will replace the old one. Micro switch has 2 plastic rods for attachment to panel, I assume I have to melt them to bond to the holding plate but when I get the old micro switch out I might have a better idea how the switch had been attached to the plastic plate.
OMG,
you may ask this guy with the same problem.
To all others with similiar problems:
Don't touch these switches in the roof shell: they hardly ever fail. As re-mounting ist not so simple, avoid touching it.
Care about the broken and/or shortened wires in the upper bow behind the rear roof shell.
