Hi there guys, I just bought my self a 2012 F30 BMW 320d M sport in AW which has already got the dynamic xenons, however i was originally planing to get one with halogen and do a full write up DIY of how to do the conversion.

Seen as i don't have access to a F30 without xenons i decided to post up this retrofit for the wiring and pin locations.

After looking at the diagrams for both Halogens and Xenons the good news is that only 4 wires need to be moved in total and 4 new ground wires need to be added into the headlight plugs to get the xenons to work (without the auto level sensors)

This 1st picture shows my notes for the difference between the pinouts for Xenons vs Halogen headlights, as you can see i have marked No 1 -3 & 5 in green as they stay the same and dont need to be moved.

As you can see above on the left of each box it shows Pin 1-12, these are the pins on the headlight connectors, and on the right it shows what pin they are and then in brackets which connector they are located in, the next 2 pictures are to help you pinpoint these connectors out.

Now to simplify things further all you have to do is add 2 new pins on each of the headlight connectors in pin no 7 and 4 and bridge/join this new cable to either pin2 as all three of them are all ground cables and join together.

There is no other work that needs doing on the headlight connectors as it is easiest to move the other wires on the FEM module, pins 9-12 on the headlights will no loger be used but can stay as they are as the new xenon headlight will have no pins in those places so they will not cause any troubles, also if you do decide to ever put your original halogens back these wires will be untouched.

Next you need to move some wires in you FEM Module

Move pin 26 from connector A173*2B to ---> pin 53 in connector A173*3B
Move pin 34 from connector A173*3B to ---> pin 41 in connector A173*3B
Move pin 49 from connector A173*4B to ---> pin 53 in connector A173*4B
Move pin 37 from connector A173*4B to ---> pin 54 in connector A173*4B

Once you have done this you can wire in Level sensors (I will be posting wiring diagrams for this over the next couple of days) or you can leave them out and possibly do some custom coding to manually adjust the headlights.

I don't have a car available to do the coding so either i will try to post that part once i have done it or hopefully someone else will try and to do the retrofit and post it up, I can however help with the coding and possibly do a tutorial if someone is willing to code their car and send me their files and i can modify them and send them back and check if everything will be working properly.

Below i will be putting some pics up of the wiring diagrams just in case someone wants to have a look at them
