LCM swap shenanigans

[kaiv]

Ok this is stupid but the solution is eluding me.

I have this CI37 LCM which I used to run in my touring now installed in my sedan. Moved it over for the triple blink feature.

Coded properly to the best of my knowledge; VIN, mileage, build date, body style, VO list etc.

Issue: the fog lights do not work. Nothing happens when I press the button. No relay clicking, no logo lighting up in the cluster, nothing.

The fogs themselves work. Confirmed by using INPA (bypassing the switch) and with a random spare (older) LCM.

The LCM also works. Plugged it in an M3 and the fogs work right off the bat.

But in my 330i the button press is just not registering.

Is there something uniquely different with the ZHP/sedan that am I'm unaware of?

Any ideas?

Thanks!
