Halogen to Bi-Xenon - Kufatec Interface

[fly300kts]

I did an upgrade today to I finally took the time to take some pictures. I know that another DIY does exist on another site but I think this one is more detailed

On Driver & Passenger side, plug the harness
Left Side

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P001.jpg

Right Side

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P002.jpg

Passenger Side:
Secure the wire to the existing harness

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P003.jpg

Remove the seal from the front frame

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P004.jpg

Insert the wire inside the seal grove and reinstall the seal in place

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P005.jpg

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P006.jpg

Install and secure both headlights. Connect the new Harness to the headlight.
Using zip ties, run both wired along the brake line. Both wires will exit the wheel well through the same hole than the rigid brake like.

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P007.jpg

Start the car and turn the wheel completely to the right. Turn off the car. Without removing any component, like the wheel for example, you will see this large grommet.

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P008.jpg

Pull on the grommet

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P009.jpg

Now, inside the car, remove the lower panel

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P010.jpg

Locate this connector by the relays
Using a small screwdriver, pull down the orange locking tab (already unlocked on the picture) and the connector will slide out his slot

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P011.jpg

Connector close up

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P012.jpg

Cut the small zip tie and slide out the pink tab

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P013.jpg

Now the grey cover will slide out the connector assembly

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P014.jpg

Let’s go back to the grommet in the wheel well. Using a razor blade or other, cut a small part of one of the sticking tube. The target is to obtain a hole as small as possible, just to be able to run the 2 wires. In case you cut too far, no worries, you can always, once the grommet will be back in place, apply some silicone from the inside of the car. Run the wire inside the orifice you just made.

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P015.jpg

Reinstall the grommet in place. Make sure that the 2 wires are secured inside the wheel well. I was not able to take a picture due to the lack of room but I added a zip tie, securing the 2 wires and the brake line.
Make sure the grommet is correctly secured inside the grove. If you cut a hole too big, you can add the silicone from here

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P016.jpg

Now you are going to connect the wires. These wires are the Hi-Beam command so it does not really matter as far as Left or Right Headlight but the position on the connector is critical. They have to be on slot 21 & 22. On this close up, to make sure that you are correctly oriented, the # 17 (red circle) on the connected should be on the left. The 2 blue arrows show the wires location, slot 21 & 22.

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P017.jpg

Make sure that the connector is correctly oriented. Just push on the wire and it will click and lock itself in place

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P018.jpg

The result should look like this

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P019.jpg

Put the connector back together and install a new zip tie

http://i31.photobucket.com/albums/c395/fly300kts/Kufatec/P020.jpg

Secure the excess length of wires and you are done !!

Let me know if any question

[MentisImperium]

all i can say, is from what i can see...that is one sexy ibis white a4

[GA42.0T]

That's one beat down thumb you got Phil.

Printing this for my install. Thanks!

[Coderedpl]

That is one way of doing it. Another is going around the area of the ECU. There is a little rubber grommet there too, many times it's used to route the tubing from the boost gauge. That's the way I routed mine. For the passenger side i went around the passenger side seal next to the intake.

[Doctor]

Well done for helping the community as always Phil.

[FASTONE]

Phil,
This is what I am talking about, very sharp!!! I still have not installed the v4's yet but will do sometime next month!!! Thanks!

[felondnb]

I routed the extra wire through the ECU too, but to get the cover off, you need to remove the wiper & a flexible socket set helps.

I was also running a 4 AWG power cable so I did both through the ECU into the driver's footwell, then ran the power to the back under the door shut/sill trims.

[GA42.0T]

Great DIY Phil, as always. Used it last weekend for my install. If I may be so bold as to suggest one small edit for the truly novice DIY'er:

Using zip ties, run both wired along the brake line. Both wires will exit the engine compartment and enter the wheel well through the same hole as the rigid brake like. See yellow arrow below.

Start the car and turn the wheel completely to the right. Turn off the car. Without removing any component, like the wheel for example, you will see this large grommet.

Also, I had to take my wheel off cause I couldn't see shirt in there - and I'm only lowered on Eibach springs.

Thanks again.

[vdubjetta02]

I want xenons.... but am to afraid to mess with anything electrical on my car.... I will install suspension, exhaust ect... but hate deing with electrical work.

[GA42.0T]

This was really easy. Barely even qualifies as "electrical work." Just run those two wires and plug them where Phil indicated. That and plug the light into the harness. Easy peasy.

I was nervous too, but and so glad I did it. The night visibality is so much better. Add how cool they look and it's totally worth it.

[Weem]

im going to be doing this upgrade next week but im confused on one thing....a separate harness is needed for each side? i was under the impression only 1 total was needed


thanks

[GA42.0T]

One kufatec harness has two connecters for, duh, two headlights. Basically the connecters for halogen lights don't fit the connectors for xenon. Xenon has one or two more prongs in the connectors, so you physically cannot connect xenon connectors into halogen harness. Won't click in there.

So kufatec harness is an adaptor between your stock halogen harness and you new xenon connector. And the extra wire in the kufatec harness corresponds to the extra prong in the xenon connector. This is the wire which Phil demonstrates in this DIY how to run and connect to CPU.

[peta8368]

thanks

I can't find the harness on kufatec's website for some odd reason.... but the picture in the "kit" shows the harness

http://kufatec.com/index.php?main_page=product_info&cPath=6_27&products_id=162


you can see that it's actually 2 separate one, one for each side, but they wrap the high beam wires together, so that process "ties" the 2 pieces into 1.
Perhaps they have updated the design since then and no longer wraps them together, but either way, it's the same idea: one adapter on each side, plus the really long high beam wires.


Peter

[Weem]

yeah i just relooked at the harness and it was just all coiled up...sorry for the mix up!!

[brucebanner]

im hoping to get my bixenons soon, but i gotta say that im not looking forward to running the wires and install. im terrible with running wires and fitting in small places. when you guys talk about running it through ECU, where exactly is that? any pics. I just want the easiest way possible

[fly300kts]

just follow my DIY

Phil

[brucebanner]

just follow my DIY

Phil

yea thats what I plan to do, the only part that confuses me is because i dont know where the break lines or anything is. but i also have never looked under my hood for stuff like that. im just kinda worried about the part of getting the wires to the grommet in the wheel well, cutting the little hole, and getting the wires into the car.

but ill just have to wait til i get everything and go to install before i start worrying about this stuff right now i guess.

and im probably 2-3 weeks out maybe even a month from getting everything im assuming anyways

Relax, once you will have everything in front of you, you will be fine
If still, you can figure it out, well, find a buddy who does of pay a Mechanic. This is really basic stuff !!

ok

[Audi Skate Snow]

great write up. props for sure!

[72mako]

Great write up Phil, as always. Thank you for making the point about the right and left high beam wires, when I did mine I couldn't figure out whether the slots were assigned to a right and left headlight or not. I'm pretty sure I followed the break line into the wheel well but it's been almost a year since I did my install.

[rvca3112]

Would these just be plug and play? Or would I have to use vagcom to tell the car I have the xenons?

[fly300kts]

You will need to WAGcom the car to enable the High Beam function

phil

[event]

I tucked mine the same way, have had Xenons wired up for like 2 months now and still haven't VAG'd them, haha... Nice write up, I had to fumble around when I did it.

[rvca3112]

Wagcom? I thought it was vagcom. Am I wrong?

[rvca3112]

What vagcom settings do I have to go into to tell the car it has xenons as opposed to halogens?

[kurupt_hawaiian]

Just upgraded my halogens to Bi-xenons today following this walkthrough. Thanks!

[null]

Hi Phil! First of all very nice and detailed post. I have a lot of your threads bookmarked for future DIY i'm planning to do..
Anyway.. have you considered buying 14 pin adapter and reconnecting all wires into it and running 2 additional wires back to 32 pin harness?
1J0973737 ($6 part from VW dealer $7.71 from Audi) is the part that is that 14 pin connector, so supposedly one can take out all the wires from halogen plug plug them into it? and then run 2 more wires ? is that true?

[fly300kts]

Can't answer, I do not mess with harnesses unless obsolete
I just buy my Kufatec interfaces

Phil

[null]

i tried connecting the headlight through the kufatec harness - and lights do turn on just not the xenon bulb. have new bulbs in there. what could it be? i just disconnected one connector from the halogen, plugged in the harness into it and into the headlight..xenon bulb doesn't ignite when i turn lights on but other bulbs light up ok.. i didn't vagcom code it.. what could be the issue?

[kurupt_hawaiian]

You need to vag it!

[kurupt_hawaiian]

I converted my halogens to bi-xenons about 2 months ago. Before I did the vag-com it would flicker which is bad for the xenons. Vag it and it will work fine.

[null]

ok i just spent an hour with vagcom trying all possible things i can think of with these lights. i have adaptive with AFS headlights with new d1s bulbs and ballasts. I plugged in the harness I bought from Jens and I vagcommed 09 controller to 00033 which bi-xenon no drl / usa. same thing - my xenon lights do not turn on. i dont understand where do i go to code so they are not AFS but regular xenons? where in vagcom is it? when i go to 029 left light controller module - it doesnt connect.
I read codes and vagcom in 09 controller module is telling code 000978 left light short, 000979 right light short.. what to do ? i tried swapping ballasts, i tried swapping headlamps from left to right..the d1s bulbs are brand new generic philips bulbs - they don't have to be audi or anything right? ?
anybody please hlp.. i swear i hear motors or something clicking when i turn of the light/ remove key from ignition - but no xenon light

[lenti]

i hope i dont have any problems with mine l8ter...
wich code to i need to change from Halogen to Xenon on a EU car?
i have vag-com cable

[Firefox250]

wich code to i need to change from Halogen to Xenon on a EU car?

I have the same question

[lenti]

well right know you should have 01012 change it to 01021 then ure done :D

[Firefox250]

well right know you should have 01012 change it to 01021 then ure done :D

Thank you lenti, is that code for non adaptive Bi-xenons? Whats the code for e-codes?

[lenti]

Thank you lenti, is that code for non adaptive Bi-xenons? Whats the code for e-codes?
The first code 01012 was for the Halogens, thats what i had on mine (Sweden)
for the Xenons with DRL you need to change 12 to 21 instead.

[Firefox250]

After installing these Bi-xenons do you have adjust the beam height? If so where? I looked in the Bently manual and did not see anything.

[kurupt_hawaiian]

There are two white screws on each headlight. One to go left and right, the other to go up and down.

[TheKid23]

This doesn't mention anything about swapping ballasts? I was under the impression that different ballasts were used between halogen and bi-xenon?

[Coderedpl]

There are no ballasts on the halogens

[TheKid23]

Cleared that up.

So the ballasts for the bi-xenons just need to be tucked away somewhere?

[Coderedpl]

They're directly attached to the housing on the bottom considering you are using OEM parts

[TheKid23]

Was also looking at the other DIY about the differences between halogen and bi-xenons, gathering as much info as I can before my swap. The bi-xenons have the DRL bulb, will I just not use that function? Obviously don't have it now.

[TheKid23]

Perfect, yes OEM. Just bought them today, should be here by mid next week.

When you code the headlights you'll see the various options of setting them up so yours can be running on if you want them to

[TheKid23]

Ok I read up on the Vagcom thread earlier and noticed that. So if I code them on, it doesn't matter that I don't have the DRL function on my headlight switch?

[Coderedpl]

Ok I read up on the Vagcom thread earlier and noticed that. So if I code them on, it doesn't matter that I don't have the DRL function on my headlight switch?

Its a little knob NEXT to the headlight switch, but yes it doesn't matter.that knob just allows you to shut them off.

[TheKid23]

Yea I'm familiar with it, I meant that I don't have it.

[kurupt_hawaiian]

If you don't have the knob and code them on...it will be on at all times, until you code them back off through vagcom.

[Coderedpl]

If you don't have the knob and code them on...it will be on at all times, until you code them back off through vagcom.

If you have 'em why not run them. they look great with led bulbs too

[TheKid23]

If you don't have the knob and code them on...it will be on at all times, until you code them back off through vagcom.

This is what I figured. So they'd turn on when I started car, would they stay on when I put the headlight switch to city light? And turned headlights on?

[Coderedpl]

Nope

[rarak69]

Im not sure i understand the need to recode for these headlights.

Do the actual OEM xenon headlights have some sort of CAN -BUS control board in it? On my B5/B6 you could swap xenon headlights, plug and play, thats it.

My b7 which i did a retrofit on(proper) i just grabbed my bixenon from the high beam wire and soldered it over to the actuator, which is a method used for a few of my buddies cars too in the past.

[B7Joe]

I converted my halogens to bi-xenons about 2 months ago. Before I did the vag-com it would flicker which is bad for the xenons. Vag it and it will work fine.

Gotta vag mine I guess. Installed earlier, and things were fine. Now it's flickering pretty bad (almost like strobe at times). Dang it, I hope that fixes it and its not that the ballast are bad. That would suck...

VAG-COM fixed it. Also followed the guide to wire the high beams. Worked great. The kufatec harness itself is excellent quality. The new ones have been upgraded and all the wires are wrapped in OEM black fabric tape. Nice touch.

DIY on this guide? i thought the high beam function was plug and play

Yes, I used this guide (DIY) starting on page 1. Nope, high beam function requires some minor wiring to work.

How did you guys get to the last bolt that hold the headlight? the ones thats nearest to the fender. Theres no way i can seem to get to it to tighten it

You need an extended Torx tip
You can also try with a long flat screwdriver that will fit the torx head

[mpv314]

The running of the yellow wire is basically enabling the high beam function. Just follow this DIY exactly, VAG COM your car and you should be good to go. I'm about to do this mod, just waiting on my VAG COM wire to come in the mail. I want to test everything to be working perfectly before I go ahead and start taking my halogens out.

Does this process also add the adaptive portion of the OE HIDs or does that require different Kufatec harness and parts??

The 2 wires are the 2 signals for the High Beam function
You need the VAG interface cable to be able to use the software

Hi. I instal xenon on my b7. Original ballast, d1s bulbs, adapters cable. And i have problem. On left side xenon is flashing... I don't now way?!

Tnx!

[jaycurn]

Hi. I instal xenon on my b7. Original ballast, d1s bulbs, adapters cable. And i have problem. On left side xenon is flashing... I don't now way?!

Tnx!

I am having a similar problem and wondering if any of you guys that have completed this retro might have experienced and resolved this? I am getting the following code:
02071 Local Databus
57-00- Electric Circuit Failure

Symptom: After the lights have been on for over 10-15 minutes the DS beam will start to flicker and cut out while driving. When the car is idle it will still flicker but not nearly as often.

I tried swapping the bulb first with a spare I had in the side that was flickering and the code persisted, but I did not have them on long enough to see if they would flicker.

I then tried swapping the ballast with a spare, same results. Will see on my drive home tonight if they will start to flicker again, but I am fully expecting they will since the same code is present.

Anyone?

[tehbry]

So I'm about to pick up my B7 Friday and I'm already planning the xenon conversion. I plan to source the xenons from eBay as I want them to be ecode. Does anyone happen to know what part number(s) for xenons will work just as its laid out in this DIY. I would hate myself if I picked up a set of xenons and it ended up being the wrong set.

Any help is appreciated, I'm looking forward to making the change from B6 to B7

Sorry to resurrect such an old thread but didn't want to start a new one

Hey man. Congrats on the new purchase.

As to the e-codes, its a bit different for the B7 xenons. So you can get Euro headlights, but my understanding is the light is aimed differently (for those left side drivers). What a LOT of members will do is open their xenons, take out the amber lenses and replace it with a clear one. They will often also "joey mod" or paint some of the chrome black in the headlight. I've personally done this before and it's not terribly difficult. There's a DIY on here somewhere. You can (or use to be able to) get the clear corner lenses from @fly300kts on this form. You may also want to buy your xenons off this form as they're usually decent pricing.

Also, be aware that the euro headlights I've seen on eBay don't have ballasts or bulbs (those will cost another ~$300). and you'll obviously need the harness listed in this thread.

Has anyone done this recently? I just purchased the kufatec harness here: https://www.kufatec.us/shop/en/audi/a4/a4-b7-8e/auto-leveling-headlights-harness-audi-a4-b7-8e

What I received seems a bit different from this DIY. Did I order the wrong item?

Major problem with this whole procedure. I'll create another thread as well.

-Installed Bi-Xenon's (OEM) with kufatec harness wired into control module.
-VCDS would not open Module 09 - Central Elec. Did a ton of troubleshooting on my computer to no avail
-Unplugged two yellow wires and the kufatec harnesses and plugged the halogen housings back in.
-VCDS opened up Module 09, finally.
-Reprogrammed for 00033 (BiXenon w/o DRL), plugged harness back in w/ BiXenon housings back in, reconnected two yellow wires to pins 21/22
-No lights, nothing.
-VCDS will not open module 09 at all. tried unplugging yellow wires again and putting halogens back in, no lights. tried bi-xenon housings, no lights. no communication with module 09 at all to recode it back to halogen.

So now I'm stuck with no headlights, no interior lights, heck no central electronics at all, and many hours wasted on this process.

Anyone got any ideas?

Double check the harness is clipped back into ecu properly. Sometimes the little hook on the swivel tab thing don't grab and the plug isn't pushed all the way in

Dude I must've unplugged and replugged that connector a dozen times in the last few hours. For shits and giggles I tried one last time after you said, pushed harder than I thought necessary and it worked! Thank you so much

Work like a charm [emoji106] now I just have to adjust them so I'm not blinding people

Edit: there should be a PSA about those style clips. Every time I installed it the orange clip was clicking in like it was secured but it needed some more force to make contact with the pins.

Anyone knows how to remove the inside headlight plug? I need to replace the wires, they all broken.

You need to crack open the headlights, only way

can you install a set of xenons with the adaptive feature and just code the car for not having adaptive and not get any error codes. looking to do a xenon upgrade on my dads car but most of the sets i find have the adaptive feature. not looking to do that.

When you do this swap to OEM adaptive bixenons, how do you correctly level the headlights since the car will not have all the leveling sensors? Can you manually level the headlights?

Yes, there are two adjustments on each headlight. Both are a white-ish plastic circle with a 6mm (I think) hex in the center. One adjusts vertical and you do it just like any normal headlight vertical adjustment, park in front of a wall on flat ground and adjust until cutoff is proper height (Google it, it has been a while since I did this, something like 30" at 25'). The side to side is the other hex and for the adaptive retrofitted into a halogen car, it does not seem to do much with the beam projected on the wall, so I just centered them in the shroud with the lights off.

Thank you so much foto this guide.

Which harness are you guys using for the conversion from halogen to xenons?

This one?

ive just received these connectors in the post and acording to the intructions supplied you have to code the power control unit to alow the high beam to work, did you have this problem.

Yes you will have to code it via vagcom to enable the high beam function. I was able to use the low beam function without coding but others weren't.

This DIY has been very helpful in doing the conversion but I have hit a snag that I need some help on (knowing the thread activity is getting stale).
It appears Kufatec has changed the harness some: the yellow runs are now gray and the terminals are far too large to fit into the BCM harness locations. I have reached to Kufatec and indicated that what I received appears to be a different revision from what is pictured (white with smaller terminals) on their website and wanted some direction on how to use. Their response was less than encouraging.

My question is: does anyone knows the terminal style or type I need in order to plug the leads into the connector Phil pictured?

You can order repair wires with the connector already crimped

The connector is the same type as my AUX input DIY

Okay so I am now having a new issue. harness is *in*, new pins in place and plugged in. I can go into Mod 9 and change the codes but nothing happens at all. All I presently have is that my City lights are coming on as my high beam, as well as my turn signals. Nothing else turns on at all.

I am perplexed as I followed the DIY to a T. Any help is appreciated.

Update: I came to realize it never says my coding or recoding has been accepted. Is that the issue?

I suspect that your interface is incorrectly wired. Where did you purchase it from?

[UniDubber]

I am having the same issue. I recently bought the harness directly from Kufatec, when connected my DRL’s come on instead of the high beams. City lights, low beams, and signals, all work as they should. I have not VAG’d the system or connected the 2 extra wires from the harness. I guess I should mess with it and see if Kufatec changes the harness.

Right from Kufatec. I am beginning to think its faulty shipping as I looked back at my original invoice and it shows: Adapter xenon headlights for Audi A4, Seat Exeo (33872), but the shipping invoice they sent me shows Adapter xenon headlights for Audi A4 B6 with B7 headlights 33861. I have to assume thats my issue.

Update: I indeed had the wrong harness.

Per the DIY I am fairly certain the unconnected leads are your high-beams and changing the coding to 10021 or whatever should fix the rest.

I’m having the same issue and I change the code using vagcom, the terminals were to large so I went to junk yard and got myself some trigger wires and still no luck, even used the combination of all codes on my avant. Not sure what’s wrong. My dash says all the bulbs are out and the city/drl light is the only thing that turns on only unsung high beam even after coding

If the two leads were too large to go into the plug in the cabin then you probably have the same issue as I did; which is you have the wrong harness. I had the exact same symptoms.

[GhostKnock]

Does anyone know if the "auto" function would work if I were to replace the switch? Does the daytime light sensor work on these?

[NYCSean]

Hi everyone, sorry to bring this back to life but I have one question before I connect the high beam wires into the terminal block: Kufatec indicates a different pin location that slots 21 and 22 and I am curious if this can vary based on the central electric control module. My CECM model number is 8K0 907 063 P. I can not seem to find this information anywhere, however I did read in a few forums that the CECM can vary based on the stock electricals which is logical.

Phil - a decade later and your DIY is still helping us out here! Thanks for the great write up.
