March 2012, I purchased a pair of dynamic, Bi-xenon headlights to replace my halogen ones. The set was already a steal at $510 but they also came with the xenon and adaptive control modules! I successfully coded VO 522 to my car and had been using the headlights for two years without adaptive functionality. I recently thought. What the heck…it would be nice if the auto leveling and adaptive features also worked! So. I started my research….

• Car assessment - My car came with pre-lci halogen headlights. I have no preinstalled wiring for the AHL (3 pin) plugs and no wiring for ride height sensors.
• Wiring – Google searching, I found a few relevant retrofit documents and found that BMW sold E60 xenon retrofit wiring harness 61120306080 but discontinued it. I decided to use the wiring diagram from E60 B-Xenon Retrofit doc 63120398577 as a basis to create my own harness. The doc recommended 0.5 mm2 and 2.5 mm2 wires which are equivalent to 20 AWG and 14 AWG wires respectively. I bought a 20 AWG kit for wire.barn on ebay that had 8 colors of 25’ each for only $32. I bought 14 AWG wire from Home depot.
• Wiring map – Since I wasn’t using the same wiring colors as recommended in the doc, I wrote up a wiring legend to be sure I knew what wires went where.
• Running the wire - I didn’t know the length of the wires for each run to various places so I just ran the cables and cut them to the length I wanted. My biggest issue was running wires to the passenger headlight. I decided to remove the air filter housing and open the fuse/adapter box beneath it. Using the old ‘hanger tied to the wire’ method, I pushed the hanger thought to the fuse box. I then poked a small hole through a rubber protective cover from the fuse box and pulled my wires through to the headlight and tire well. There was nothing tricky about running the other wire, just a lot of work.
• Making the connections – I had to buy the correct connectors to fit in the pin slots of the LM and crimp them to my wires. I again follow the doc to the letter, plugging the wire exactly where stated.
• Appearance/Protection – I did want the job to look like it wasn’t from factor so I bought multiple roles of black fabric tape and wrapped all wires for protection and for the factory wiring appearance.
• AHL – the E60 B-Xenon Retrofit doc 63120398577 did not reference AHL wiring so I found Retrofit AHL (Adaptive Headlight) doc 63120412059 in German only. After translating it, I found that it was nearly the same as 63120398577 with just two differences, grounding LM wires 58 and 59 to 56 and running a twisted pair cable to the LM. I did that, the proper coding and bam! I now have fully functional dynamic bi-xenon headlights.

hi! xonreh

It is a very good job!

I am also working to retrofit adaptive headlights.

Now, most functions is working properly.

Two questions here

· Did you follow the connection of 71 & 72 PIN fromPT-CAN?
· Did you follow the correct connection of the LIN-BUS 16PIN from RLS?

It does not establish a complete action If you do not do this connection?

Thanks!

 

Hey how is the dynavin unit does it do everything it says. Are the graphics good. Where did you get yours

 

Pm sent

 

i am aboug to change my headlamps as exported the car to Spain and right hand drive headlights are no good here
as I’m buying new headlights anyway, would it be beneficial to upgrade to bixenins at the same time?
Do gheh bake much difference to vision at night?
Lots of twisty mountain roads on the island I live on
thanks

 

Hey,
I know this is an old thread but does someone still have those documents or guides on how to retrofit bi-xenon AHL? I would like to have a diagram of how the headlight level sensors need to be wired and what is needed to get the adaptive headlights to work.

Thanks.
