After a year of trying to figure it out, it finally works!! A big thank you to ifr for finally providing the final piece of coding that was causing the holdup!
It seems that in addition to the codes originally found by simpaty, BMW is using additional codes to block certain features from working in certain countries, based on where you are located. By changing this coding, you can enable the Lane Change Assistant to work regardless of your location.
The 3 codes to be changed are:
HU_NBT or HU_MGU:
Spurwechselassistent - Change this to Aktiv
SAS Module:
C_SWA_Vorhanden - Change this to True
C_SWA_Land_Aktiv - You will have to edit the Werte values to "FF, FF, FF, FF" This is the item that blocks it from working in certain regions.
And, the proof!
