If the retrofit is done on a MID FEM the shutter will not work if the wiring is done upon the normal Xenon retrofit wiring, You have to let the shutter wiring work on the normal halogen high beam and then code it.

I mean
on the left headlight:
Let pin no.6 on the headlight ---- which is pin no.26 on A173*2B on the FEM the same on both ends (don't remove it).

on the right headlight:
Let pin no.6 on the headlight ---- which is pin no.34 on A173*3B on the FEM the same on both ends (don't remove it).

then code FEM:
MAPPING_FERNL_1_L_OUTPUT (change from 18-bix_l to 7-fl_l)
MAPPING_FERNL_1_R_OUTPUT (change from 18-bix_r to 7-fl_r)

This will change the output channel for the Xenon shutter inside the FEM from BiXenon (which is not supported by the MID FEM) to the output channel of the normal halogen high beam and enjoy your Xenon without replacing the FEM .

You are a crack Master, friend.
