its interesting to know what Im changing thanks
No problem, ask as much as you want.

The "MAPPING_TAGFAHRL_V_L_OUTPUT = off" means to disable the DRL.
About this i'm just wondering.
But these coding values are for the original LED retrofit like i said.
Maybe the DRL is working in a different way.
I just compared this value with my settings.
I have adaptive xenon lights and my settings are MAPPING_TAGFAHRL_V_L_OUTPUT = tms_leuchtring_l.
It means Light ring or the eagle eyes.

The "MAPPING_TAGFAHRL_V_L_PWM_LEVEL_1 = 11.5V [Default]" is the permanently set voltage for the daytime running light.
But if the DRL is permanently switched off by the first coding value so it's nothing worth.

TAGFAHRLicht=daytime running light or DRL.

Hi,

Same issue but my high beam and low beam are LED as well. They flicker crazy... The left one in particular. BTW theyre the same set of headlights but replaced halogen to LED. What All do I need to code?

Hello !

Same problem for my car, a 2015 F30 (pre-lci model). I only replaced my halogen bulbs by LEd bulbs with anti-error box and all of my headlights are flickering when I start of the car, then they are flickering randomly when driving, except those that are lit.

Any idea, guys ?

Thanks so much, best regards.

That's the cold and warm checks. They don't cause halogens to flicker because of the way halogens work. LEDs work differently from halogen, so they flicker. You have to code out the warm and cold check on any LED bulb circuit.
