Use electrical tape and wrap it around the wire until u have a wide enough circle to fill the hole to prevent any moisture getting in there as shown in pic#7[/SIZE]

Hi

Any solution fo this issue, please !!

With this simple 2 wire mod do the xenon headlights retain all functionality? Hi/lo beams, halos only and stalk hi/lo flash?

I guess an easier way to ask would be do they lose any functionality lol

many thanks!

Yes you'll retain all functionality. The only reason additional wiring is required is because:

1. The xenons have a separate ground for low beam (which doesn't exist in the halogen loom)
2. The xenon has a shutter that opens on high beam (this is the bi-xenon) so by wiring this into your high beam wire your bi-xenon will operate alongside your normal high beam.

The factory bi-xenon cars control the shutter independently via a wire from the FRM, but for normal day to day driving it won't make any difference.

If both the old and new headlights are pre-LCI and non-AHL then the only difference should be an additional thick brown wire in pin 2 (second ground for the xenons) and a thin brown/yellow wire in pin 5 for the bi-xenon flap actuator.

The relatively small number of wires on your original lights suggests that you don't have electric levelling (either manual or automatic), as these use an additional four wires - one pair for the motor and one for the sensor. These are usually in pins 8-11 although this doesn't seem to correspond to your harness so you'd need to do some investigative work with a meter.

Hello dear people, I have a problem, don't know where to start, drive an E90 2005 halogen headlight, have now bought the xenon headlights from 2006 and an FRM2 for my car. I don't know how to wire up correctly, which pins go where. Can anyone explain that to me? for stupid ones like me. I have already retrofitted the electrically folding side mirrors, but I had the right plan and knew which pins belong where and how many additional cables I have to lay. these are normal xenon headlights without cornering lights and not bi xenon. help me please

Why not upgrade the xenon lights you plan to put inside as headlights are removed? This way you improve the improvement.
Below is the image of normal bi-xenon headlight housing without the projector.
You can remove projector from the headlight from the back opening. It is not easy, lots of figuring out right angles and slightly needed to disassemble projector (metal piece) & headlight (leveling adjuster).
It will come out eventually in one piece. In the below image i've put adapter there (purchased projectors from retrofitlab - their aluminium adapter is wrongly made or for different headlight?). The adapter was not really alignied with the bottom tab but a simple aluminium piece solves that.


Here is comparison between projectors (OEM bi-xenon vs Bi-Xenon ZKW).


They are definitely better than oem projectors. Main difference is how the light is spread. Oem spreads it evenly around everywhere while it lacks distance.
So you feel like, want to upgrade the high beams. Some of the light is lost due to lenses not beeing clear but "foggy". The cutoff is not sharp but softer. Oem projectors illuminate sides better but while driving it is not where you concentrate your focus.
Most used ones have slightly burnt projectors (because most use headlights in auto switch) where it uses HID in daylight. So this is another reason to swap them out.

The new projectors focus is directly ahead. It is similar to a "V" shape spread where it does not show light directly next to the headlight (like oem's do). The light is focused instead ahead where you want to see better.
Because of this the overall beam strength is better where it outperforms most xenons that i have compared to while driving in the dark. The sides of the road are better illuminated and can detect incoming animals earlier. Halogens (2 low beam + 2 high beam at the same time) are worse than a single ZKW projector in high beam mode. Light spread is just too good in ZKW.

When the shutter is pulled down (bi-xenon function) the high beams are one the better ones. Clearly the design is to focus most light ahead of you and this is what most OEM headlights are lacking in.

This is something worth considering doing while headlights are removed from the car or you have two sets. Best investment so far, even better than CDV delete. But be aware, messing with lightning always takes some time to get everything right. One warning is that mount the bulb correctly first time in the projector - saves you time from taking everything apart again. Light focus needs to be centered and gradually spreading out. Any anomalies here means something is off.

For last car retroitted FX-R 3.0 the cutoff was nice but these are now preferred choice.

I have a few questions, for those who have done this:

- Can the xenons be aimed like the halogens? I know the auto-leveling won't work because my car lacks the hardware (2006 E91 with halogens).
- Do I need LCI non-AHL housings, or can I use AHL headlights and disable the AHL function?

Thanks in advance.

I did this mod yesterday, using pre-LCI headlight housings.It turned out great. I ended up doing the wiring splices inside the housing. Once you take off the ballast, there is plenty of space to remove the loom from its socket and get at the wiring.

Just done this mod, however I didnít fancy hacking my factory loom or the wiring inside the lighting unit so I created my own harness and itís worked a treat. Just need to fit them in now when I can face taking the bumper off. Question I have is do I just need to code the xenonís in $522 and deactivate the auto levelling? And will the manual dial still work to adjust?

I need some quick help on this topic. so I have a 2011 LCI car with halogens and I installed the factory Xenon lights, and spliced in the grounds just as mentioned. The side markers, blinkers and low beams work, but the daytimes, halos and highbeams donít work. any help would be appreciated, Iím not sure if some additional coding is involved.

Sorry if I missed the answer to my question, but I read all these treads to convert my 2008 e90 pre-LCI halogens to HIDs and couldn't find it.

This error that comes on for a few seconds when the car is started, 96vette stated it's for a low beam malfunction. My understanding from Parachute's mod is this error is due to the difference in wattage so can't this simply be coded out with Bimmergeeks pro tools and delete the low beam bulb check?

Also, the hum from the HID shutter... If wires #5 and #6 are not spliced to activate the shutter we obviously can't use this function with the D1S bulbs, but do the high beams still flash normally?
