F34 Adaptive Led Retrofit

I have a problem with adaptieve led retrofit, i have an F34 with adaptive bi-xenon from 2014.

Did the wiring according to newtis info, changed date to 1116, deleted 522 and 524 and added 552 and then vo coded FEM, REM, added CAFD to FLE43 and FLE44 and vo coded them to.

Now the problem, low beam, high beam, turn signal and vertical aim are working. What is not working is the DRL and part of the adaptive function. When i turn right lights go right, when i turn left nothing happens.

On my cluster i get drl defect and if i read out with ista it says open circuit, no error for AHL.

Annyone had this problem or know what the problem is and how to fix it? Cause im out of ideas

No didn't code KAFAS (but HBA works fine) so don't think KAFAS needs to be coded?

I rechecked wiring allready 3 times, everything is connected like on the schematics. Yesterday i even removed bumer and lights again cause in ista it said to switch fle from side, problem stay the same.

The faults according to ista are
8059A1 FLE02_L: Classification resistor 3 invalid
8059A7 NTC 3: Line break, temperature sensor
805CBC Daytime driving lights: open circuit
805E3C Daytime driving lights: open circuit

But after you delete every fault, the 2 first disapear and the 2 open circuit stay but then say non excistent

Make sure the headlights are the correct spec. US spec headlights have side markers and EU does not iirc. Ran into the same issue during install.

i updated sevral modules (of witch fem and rem) to latest istep before i even descided to do adaptive led retrofit. so thats not the problem, neither is the wiring and neither is the coding.
