iDrive Headlight Sensitivity Adjustment

Thanks to rubodm!

I just coded the auto light sensitivity control in idrive. I hate that the lights come on even when its bright outside. Here is what needs to be changed:

Control unit: CAPPL

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

Please reply if you've done this and provide your experience on the actual adjustment results (do the lights come on later?).

I just coded this to my idrive. I'll report the changes.

Right now the lights instantly come on when going under an overpass. I'll go under a parking structure and see how long it takes for them to come on now. I set the sensitivity to slow.
