To my knowledge this has not been done, there are way to many differences between the setup for halogen and the bi-xenon.

Although Toby can speak for himself I am pretty sure it did not work (he would have said something if it had) toby ?

I asked my dealer a long time ago. They would not even give me an estimate, there is a parts list thats very long and re wiring out the wazoo.

Good luck.

Why dont you just change the bulbs for bright white or trade it in for an equipped car. I went for Air but could not get lights with air.

Air is better than lights imho.

Ok, afther take a closer look of this thread: http://www.renntech.org/forums/index.php?showtopic=1189&st=0

Is pretty clear that nobody in this forum have done this. so i have to make my own research...

Step 1) take the car to the dealer, if they can`t programm the vehicle to xenon headlights this will lead to the step 2...

Stay tuned

Done!

Things you need to know...

you DON`T need the bixenon wire harness (part no. 955 631 239 10) to make the bixenon headlights work. I re-wire the internal of the bi-xenon headlight.

* The only diference are:

1) bi-xenon have an extra light called (cornering) i tap this to the xenon wires, every time the xenons turn on both cornerin lights goes on. ALSO this prevent the computer detect a problem whit the low bean xenon ballast.

2) I tap the bi-xenon shuttle whit the auxiliary high beam lights, if i don`t have the xenons on and i flash the high beams, only the auxiliary and the shuttle goes on, NOT the xenon. there is a resistor in the shuttle that you can remove (more details next...)

* Start

1) Take out both headlights (Please see manual for more info)

2) Take the 3 covers out

3) Remove the Autoleveling motor (remove the 3 pin harness and two bolts) from the Halogen headlight

HPIM1446.jpg

4) You have to take out the Pin conector, to do this insert a plastic (Use an old Credit card, cut it in two and then resize it to 3cm wide) insert the plastic at the top and bottom inside the housing make sure it reach the end and then pull out the connector (This is a pain in the a..)

5) Once the connector is out start to cut each terminar as long as you can, NOTE: don`t cut the 3 pin connector in this harness you will use this whit the autoleveling motor in the bi-xenon headlight.

in the end you will have this:

HPIM1476.jpg

6) Say bye bye to the halogen headlight... don`t be panic now...

7) Remove the 3 covers in the bi-xenon headlights

HPIM1467.jpg

8) Now remove the Autoleving motor (remove the 5 pin harness and two bolts), then install the 3 pin Autoleveling motor

Side by side (Left Halogen 3 pin, Right bi-xenon 5 pin)

9) Remove the xenon ballast in the bi-xenon headlights (6 bolts) then disconect the harness, now remove the 5 pins (thin black, thin brown, red, yellow and uncovered ground wire) you only need two wires to turn on the xenon (Strong black and Strong brown)

10) Cut all the wires in the connector (bi-xenon headlight) NEAR to the connector and then use the plastic trick to remove it from the headlight.

Take the Halogen connector and use this diagram:

PIN 1 - Parking Light Lead (+)

PIN 2 - High Beam Adjuster Supply

PIN 3 - High Beam Adjuster Sensor

PIN 4 - High Beam Adjuster Ground

PIN 5 - EMPTY

PIN 6 - Low Beam Lead (+)

PIN 7 - High Beam Lead (+)

PIN 8 - Additional High Beam Ground (-)

PIN 9 - Turn Signal Lead (+)

PIN 10 - Low Beam Ground/Parking light/Turn Signal (-)

PIN 11 - EMPTY

PIN 12 - EMPTY

(tanks to toby http://www.renntech.org/forums/index.php?s...pic=1189&st=20)

11) Tap every wire as this diagram says, note that inside the headlights (Halogen / bi-xenon) the grounds wires are brown and leads black

12) if you want to, remove this resistor from the bi-xenon shuttle

HPIM1477.jpg

13) Remember to tap the bi-xenon shuttle + Auxiliary high beam whit the pins

PIN 7 - High Beam Lead (+)

PIN 8 - Additional High Beam Ground (-)

Corner light + xenon ballast whit

PIN 6 - Low Beam Lead (+)

PIN 10 - Low Beam Ground/Parking light/Turn Signal (-)

14) Check all the wires, solde and insulate all wires.

15 reinstall the xenon ballast, connectors and you are done!

Very interesting, how did you handle the cabin controls ?

How many hrs did it take and whats your cost including dealer work ? A lot of people will want to do this. Any warning indicators on the dash when you were done ?

Mike

Nice job! your the man!! Never let anyone tell you that its not possible.
