Main lines / steps :

1/ Visual Inspection of package and package contents
2/ Replacing Halogen H7 bulbs with HID H7 bulbs
3/ Testing HID Kit
4/ Fitting and fixing ballasts
5/ Cutting a hole in Low Beam Compartment Cover
6/ Replacing Low Beam Compartment Cover
7/ Connecting Ballasts / Bulbs
8/ Removing fuse 32 or Reflashing the LCM



STEP 1 : Visual inspection of package and package contents

Open your Xenoflo package and inspect components to ensure nothing is damaged or missing. Package contains :

02 Xenoflo ballasts, each one has a hardwired cable and a connector port
02 Cables, 2 wires each, one connector each side
02 Hid bulbs with wiring
02 Black plastic holders for ballasts
02 Double side adhesive pads
06 Screws
04 Zip Ties

If nothing is damaged or missing (That rarely happens with bimmian products), you can proceed to step 2.


STEP 2 : Replacing Halogen H7 bulbs with HID H7 bulbs

Important notes :

1/ Before you start, MAKE SURE that key is not in ignition, and that engine, engine bay area, headlights, and bulbs are COLD to avoid injury !
2/ Do not, under any circumstances touch the glass of the old or new bulbs with your fingers. Always take the bulbs from connector side. Do not scratch the glass of the bulbs.


What we are going to do is replacing our stock H7 halogen bulbs with the new H7 base HID bulbs. Look at the picture below : the two bulbs have identical bases, so no gluing, drilling, or bulb holder grinding is required !

STEP 02.01 :
Now open your hood, locate your low beam compartment and remove the black plastic cover on top of it. You can see the H7 Halogen bulb, held by a metal clip , and with a connector plugged in.

To remove the H7 halogen bulb, unplug the connector from the bulb, press the metal clip towards the front of the car, maintain it pressed and push it down (towards floor or bottom).

The metal clip is now loose. Fold it back and remove the bulb. Set the bulb aside in a safe place.

STEP 02.02 :

Now comes the difficult or tricky part. You have to completely remove the metal clip, as the HID bulb has wires that will not allow you to fasten the clip after inserting the bulb in the holder. Press the clip gently with your fingers and put it aside.

STEP 02.03 :

Install the new HID bulb, ensure the plastic tab on side of the bulb base is correctly fitted between the two metal tabs on the bulb holder.

STEP 02.04 :

Now work your way slowly to reinstall the metal clip. Once the metal clip reinstalled, fasten it back.

STEP 02.05 :

Now take a look at picture 02.05. The stock connector that was plugged in the bulb is now loose. Look at picture below. There are two blade connectors in the new HID bulb wires, one is on a black wire, the other on a red one.

The stock connector has a brown and a yellow wire. BMW are known to use brown color for ground, but we never can be sure enough, so it’s time to use the multimeter. Switch on your multimeter and set it to Ohm/Impedance mode. It should display the value 1. When making contacts between the two ^pins of multimeter, it should display a value under 1 and/or beep. WITHOUT turning ignition or lights on, contact one pin of the multimeter to a good ground point (best and nearest are the bolts on top of shock tower), and the other to the metal female blade connector of the stock bulb connector that leads to the brown wire. The Multimeter should beep now. If not, try the yellow wire. Assuming the multimeter beeped on brown wire, connect BLACK wire from HID bulb (-) to BROWN wire on stock connector (-), and connect RED wire from HID bulb (+) to YELLOW wire on stock connector (+).

Repeat steps 02.01 to 02.05 for the other side / headlight.
Once the HID bulbs are correctly installed and plugged to the stock connector, we can move to STEP 3 and test our HID Kit.

STEP 3 : Testing HID Kit

You have now three plastic black connectors on the wires coming from the ballast. Connect them to the three plastic black connectors on the wires coming from the bulb. Ensure to place the ballasts in a safe and steady place in the engine bay.
Turn the engine on and let it run for a few minutes. Turn on the lights (Low beams). When lights are on, the LCM (Light Control Module) runs 12V power through the stock wires (Yellow and brown) that are connected to the red and black wires going to the ballast. So the power scheme is :

Stock with Halogen Bulbs :

LCM ----12V***61664; Halogen Bulb (55W)


After HID install :

LCM ----12V***61664; Ballast ----20000V-> HID Bulb (35W)


Upon turning on the lights, you may come across two issues :
1/ Have a bulb out warning on dash
2/ Have your xenon lights flicker (if both xenons flicker and act the same, it is normal, but if only one does, you may recheck connections).
To avoid these issues, if you have a 1999-2001 E46 coupe, open glove box, open fuse panel and remove fuse number 32. If you have a 2002+ coupe, you will need to reflash the LCM (Light Control Module) at the dealership to solve the problem.
These are pictures with 100W Hyperwhite halogen on driver side and Xenoflo 6000K Xenon on passenger side.

ID:	212269

Now turn off lights and ignition and let your engine cool down.

STEP 4 : Fitting and fixing ballasts
Disconnect the two ballasts from the bulbs. Take the two ballast holders. One hole on each holder must be enlarged with a 10mm drill bit to accommodate the bolts in the engine bay. Stick in the double side adhesive pads, one on each holder, by peeling the protective film on one side of the adhesive pad.

Now peel remaining side and stick the ballast to the holder. Pass the zip ties through the holes and secure the ballast to the holder.

You can now mount the two ballasts in engine bay, using the two 10mm nuts and the 10mm wrench.

STEP 5 : Cutting a hole in Low Beam Compartment Cover

Drill a hole in the center of your Low Beam Compartment cover (10mm to 15mm drill bit). Use the Scissors to enlarge the hole slowly. As you work on enlarging the hole always measure ! The hole must be 23mm. At the end grind the hole to remove plastic debris and smooth the edges.

STEP 6 : Replacing Low Beam Compartment Cover

Pass the three connectors of the bulb wires through the hole in the Low Beam Compartment Cover.

Pull gently on the wires until the rubber cap reaches the edge. Work slowly to make the upper edge of rubber cap sit on top of the hole.

ID:	212278

Set the cover in place and secure it (You should hear the sound of the plastic lock).


STEP 7 : Connecting Ballasts / Bulbs

Now reconnect the ballasts to the bulbs as done before. This part of the install is completed.

STEP 8 : Removing fuse 32 or Reflashing the LCM

Please note that this install was performed on a 2000 E46 coupe (built 1999). On 99-01 coupes you can remove fuse 32 from the fuse box in glove box to get rid of the light out warning on dash and the LCM check bulbs function (this makes the low beams flicker in some cases). On some models, you only get a light out warning on dash when the lights are turned off, because the ballasts being not powered, the LCM cannot “see” the bulbs.
On 2002+ E46 coupes, you cannot remove fuse 32 and you have to reflash the LCM at the dealer.
In either cases, please note that keeping the Xenons flicker may damage the bulbs.


Thanks to Bimmian, with its usual premium quality products, especially Ian for his help and support.

Additional Notes : 6000K Xenoflo color

Ok, info to share about the color. Last sunday after lunch, me and my beloved took our cars for a short drive (15kms). Good daylight but cloudy, no rain. She was driving in front of me, and when we arrived, she couildn't stop talking about the color of my xenons : Very beautiful, not purple, but very white, with light but very noticeable blue reflections. Important to say that my 6000k Xenoflos are installed in OEM projector headlights, the ones sold stock for halogens. When you have a close look at the projector glass lense with lights off, you can see the lense glass is blue tinted. That explains the beautiful color of the 6000Ks. I never tried, bought, or seen aftermarket projector headlights like the popular P46s, so it may give different results.
On the way i saw oe e46 sedan and an e36 coupe in incomming traffic. Both had Xenon retrofits mounted in halogen housings. What it looked like ? Even in the daylight, it was visually very ugly : like the sun fading at end of the day, beams, reflections, light scattered, bad beam pattern ... plus the e46 had the Xenons flickering ... Sure the owner never heard about e46fanatics.com !!!!!

it's not the glass ball. that's what your 6000k bulbs should look like. it's white with a hint of blue.

The Glass Ball looks blue even when lights are off. I've heard a lot of fanatics here saying that 6000K look purple/pink, and even experts and vendors say that color may vary depending on projector specs. Lack of rxperience and experiments, it's my first and only xenon install My humble opinion

Did you just go to the dealership and ask them to flash your module?

How much did it run you?

No, no LCM reflash. There might be some confusion about my car. It is a 08/1999 built E46 coupe, euro spec, and i have done the facelift myself in 2006 (changed hood, fenders, headlights, and bumper). With that in mind, it is obvious that i have one of the old LCMs, that can not handle Xenons or be reflashed for Xenons. This kind of LCM is present on 1999-2001 coiupes, the 2002+ coupes have the nex LCM. So i just removed fuse 32. The pros are : No trip to dealer, no LCM reflash, no new LCM, no flickering Xenons, no bulb out warning light on dash. The cons are : When i run a LCM diagnostic with Carsoft 6.5, i always get a "fuse out error"
