So I talked a forum member on this forum, I finally decided to keep xenon headlights with HID kits. He is an expert for lighting and he sold custom harness wires and it works fine since Feb.

I talked to people that have done to swap xenon headlights with many parts.
They never recommend to swap them even though they made it successfully.
Because M3 is all same, but results will may vary.

So I recommend that you keep the xenon headlights and install HID kits.
The result will be very good as you expect.

If you still want to swap them, contact Lightwerkz.

Sure, if you don't care about bi-xenon functionality. That's what you get for believing what a dealer tells you when it comes to retrofitting anything. The accumulated knowledge here dwarfs that of the dealer network, in that regard.

If you want it, and I did, it is easy to implement. As I mentioned in a previous post, simply plug in the OEM bi-xenon lights, run one wire from the LCM to the center pin of the three pin ballast connector on each light, and have your shop flash the LCM for xenons. That's all there is to it. You can order the ballast connectors and tell your shop exactly how to connect the wires, if you can't do it yourself. Before 2002, you will probably have to replace the LCM or do some extra wiring.

The only thing you won't have is leveling. Yesterday I was testing the leveling motors for my new project in the factory bi-xenon, 2002 330Ci, and I realized that the shafts are fully extended when the motors are activated and the car is level. That means they can only retract to lower the lights, they can't raise the lights. Others have mentioned that the sample rate may only be once each minute, so with both of these facts, it is obvious that leveling is only intended to compensate for extra weight in the rear of the car, nothing else.

The problem is I don't have skills and knowledges as you are. Definitely, I still want to bi-xenon lights without HiD kits if it will gurantee to work and low cost. Do you have DIY photos or video clip?

been 3 years since i did this.....but from what i remember, for basic functionality you do not need to run additional wiring. all you need is the correct LCM, the OEM bixenon headlights and a reflash of the LCM by your dealer.

i have a box with the parts i put together to enable the bixenon motor, it's laying around somewhere and i haven't gotten around to installing it yet, but once i do i will post the info on here....

in the meantime, do a google search for the term: e46 bixenon wiring

the 4th link down is titled "Bi-Xenon Retrofit DIY Instructions Models: Facelifted E46 with ...". it is a pdf file. click on it and read thru it, it is what i used to buy all the parts i needed to do the bixenon wiring.

hope this helps.

Agreed, if you just plug them in and do nothing else, the xenons will work for low beams and the halogens, for flash to pass and high beams. The only issue is that you will probably get errors, but you can add error cancelers from most lighting vendors.

Sorry, I don't have more pictures but there are DIYs around the forums.

reading thru the PDF i got from the previous post, you will see the bixenon function circuit is really pretty simple. all you need is the parts listed, and the core of the circuit is basically the relay. the guy walks u thru doing it in an 'oem' fashion.

any automotive electrician can handle this install without any problem. i chose to do it myself and i found the box i had the parts in, so it's a matter of finding some time to pop things open and finish the job so i can have constant high-beams when i need them.

getting all these parts in order including the leveling sensors for the suspension is no big deal....

http://www.realoem.com/bmw/showparts...87&hg=33&fg=30

the harness that connects them to the LCM is the big deal, getting one and then installing it properly would probably be the biggest hassle.

^ thanks !

so i have been digging around a bit and i made some progress. for the autoleveling function to be enabled, the sensors and harness (and possibly an additional control module) would have to be installed.

so far from real OEM, we have all the parts listed here (sensors and hardware):

http://www.realoem.com/bmw/showparts...87&hg=33&fg=30

i found a thread in another forum, look at post # 16, there are a few harnesses called out as well as the control module, namely parts # 61129416972 (harness) and 61358375964 (module).

the thread (look at post # 16):

http://www.bimmerfest.com/forums/sho...d.php?t=297241

i am still debating whether the control module will be necessary for the job, as i updated the LCM to a later model when i installed the bixenons, and had it recoded. it may be necessary to install this module and recode the car again. i don't know where i'd find this module in real OEM, as it's not in the section i pointed out....if someone knows if it exists or if it's on real OEM, let me know so i can take a look....it may be under a different part number for the e46 M3 as the module i quoted above is for an e39

Default Re: bi-xenon headlight swap from euro M3, question

Did anyone find out how to source both of the grommet/boots at the ballast terminations? I doubt BMW has a separate part number for them, but I would really like to protect the termination.

Junkyard?

In either case, the stock connectors are supposed to be sealed (notice the grommets around the wire). The boots are more for looks. Early bixenon cars did not have those boots
