Hey my fellow f25’r.

Has anyone retrofitted halogen to oem xenon headlights on a Lci f25 x3?

I have a 17 BMW X3 f25. It came with stock halogen headlights. I acquired a pair of oem xenon headlights and have completed the rewiring to my plug in order to work with the xenon headlights.

This is what was done.. I Added additional ground wire to pin#4 and 7. And then I tap 4&7 to #2. And then I moved pin 12 (green/blk) parking lights to #8. And moved #6 (high beam) to #9

So my local coding guy have started the recoding on my vehicle to accept the xenon headlights. We were able to get the turn signals and low beam (xenon) to work. No errror/warning code.

As for the ae drl we are having issue activating them. And for the high beam shutter I didn’t really care for it so it is not activated. ANY HELP FOR THE LED DRL!??

Here are some pics of the car, lights and rewiring.

use BMW NEWTIS. search it on google. You have wiring diagrams there.

I gotta ask, why? Maybe you only drive in the city? I couldn't do without them.

Hey pungo, so the back story i started with this retrofit with the help from another member on bimmerforum. He did the complete halogen to xenon retrofit on his 17 x3. in order to get the high beam to work it would take a bit more extensive labor running additional wiring from frm to the new headlights. Hence why I decided not to do it and plus where I live I rarely will ever need it. (The guy never activated his high beam either)

Unfortunately they guy who was helping me, he could not get ahold of his coder. That guy is dealing with some family covid issues. So I’m sort of stuck at the moment trying to figure out the ae drl coding myself. And from what I was told it is a coding issue. The rewiring is done correctly as it mirror to the guy that helped me with the retrofit.

Do you have adaptive headlight or not? because they run on different signals. DRL for adaptive uses KCAN3 and non Adaptive uses VCC_TMS signal and LM_LIN_1 for DRL.

If you have all the wiring correctly done you only need to add 522 or 552 (depending on your headlight )to your FA then VO code your FRM

The xenon headlights are adaptive.

So what needs to be changed for the coding?

You don't need to do FDL coding you only need to do VO coding since this option was available from factory.

Adaptive Xenon have 9 pin on the connector and non adaptive have 8.

Non adaptive High beam, low beam:

Non adaptive DRL: https://www.newtis.info/tisv2/a/en/f...hts/1VnXkcdPXa

This is X4 pinout but it's the same for X3 they share the same headlight and FRM

Thanks willywi. The wiring is done exactly like the adaptive diagram.

So what parameters need to be change to vo coding?
