I'm assuming there is a value (wert) that can be selected to adjust the sensitivity (or ambient light level) that triggers the headlights to turn on, just don't know what variable and which "wert" to choose.
Yep got mine to work. I enabled the function in idrive but not sure how you do this if you don't have idrive. I set it to "slower" The sensitivity is perfect now. This is in the spreadsheet.

Here is something you could try if you don't have idrive: Wert_01 should be "slower" which means it won't be so sensitive.

Control unit: RLS

FLC_SCHWELLWERT_SATZ
wert_01]
wert_04] = sensitive

wert_02 = normal
wert_03 = very sensitive



Here is the entire settings if you want to play around with it;


[Light sensor sensitivity settings menu in the iDrive]

Control unit: Cappl

RAIN_LIGHT_SENSOR
nicht_aktiv -> active
C750A_SCHWELLWERT_EMPFIN
par_gesperrt -> par_frei
C750A_SCHWELLWERT_NORMAL
par_gesperrt -> par_frei
C750A_SCHWELLWERT_SEHR_E
par_gesperrt -> par_frei

and vehicle application by:

FLCN + = normal threshold
+ FLCS = threshold very sensitive

[Light sensor sensitivity setting]

Control unit: RLS

FLC_SCHWELLWERT_SATZ
wert_01]
wert_04] = sensitive

wert_02 = normal
wert_03 = very sensitive
