Hello! I decided to install full led headlights on the bmw x3 g01 2019. I used to have halogen headlights. Tell me, bullask, is it enough to code the S552 function into the package?

Have you checked wiring? is bdc2 compatible?

i am newbie I thought that only coding was enough. Can you tell me how to check the headlight wiring and the bdc2 module?

For BDC2 either do calculations with ESys yourself or provide here FA and SVT. For wiring check wiring diagrams and compare if/what wires need to be changed/added/removed.

i think you also need change coding on rear lights when dont have high version led rear lights
I change 5a4 to 552 headlights need only fa coding dont need changing wirings

I replaced the regular headlights with LED (5A4) in the G01
without replacing the rear lamps with LEDs, change the FA / VO to 5A4 or Adaptive led 552,
then use FDL coding to set regular rear lamps,
replacement of rear lamps only indicated when changing from US to EU region
