DIY Halogen to Bixenon- Conversion Complete.

[DavidB8]

HEy guys looking for a bit of help from those that have completed the conversion or have the adapters to do it.

I was contacted by a member who purchased a car and someone had installed HID and LED tails. Now instead of using a conversion harness for either of them they hacked the hell out of the original car harness. The member was under the impression the conversions where done properly and just needed coding.

For the front they cut off the original connector and just spliced a bunch of wires together until they had partial lights functioning. I was able to work with the guy to get his rear light wiring corrected and lights coded so all those faults are gone but the front is just a mess. I got enough coding done so the car is functional but far from done.

Bentley is missing the entire pin out of the light on the right side and the there are a couple of wires that are vague for the HID. I was hoping someone could post the conversion from their adapters so I can try and give the member a proper wiring diagram to fix this mess. Although it will never be as nice as a conversion harness at least he can get rid of the errors and have proper functioning lights.

Help would be appreciated. To whom ever did this to the car you should be ashamed of yourself. Guys don't hack your cars to save $100.

So if I understand you correctly, since this guys harness/connector is already hacked up you are going straight to the HID connector (not back to stock connector form and then to new adapter)? When I get home from work I could try to get the pin/wire color info from mine if that helps.

What the person did when they installed them was cut off the 10 pin connector and then spliced on the plug and wires from an HID car. My guess is they found an accident car and just cut the plugs and wires off of it. They thought hooking up the highbeam wire direct to the shutter would work (which it doesn't) so I'm hoping the wiring they did hasn't damaged the lights. I can see some obvious mistakes but there is a couple of wires that could be easily reserved just looking at the schematics so I wanted to find out the pin out of a proper harness so I don't give him incorrect instructions.

[DavidB8]

Just so you can see what I'm trying to help him fix. Have pity..

[jbradle7]

You need both sides or just the right(passenger) side? I'll need to unwrap my harness to be able to see what wires go to what pins on the HID connector.

[DavidB8]

Been scratching my head on that one. I think the left side. The diagram on the right side is missing the in numbers for the halogen lights. So if I had the right side I wouldn't be able to do the conversion with out the colours and pins of the original.

If I have the left side though I can use it to figure out what wire controls what function then convert that to the right using colour to function instead of pins. If that makes sense...

In short, left side please :)

[jbradle7]

Ok here's the driver's side harness info. I'm going to include some extra info you may not need but someone else might later:

[jbradle7]

... and I'm not exactly sure how HID pin# 14 receives a wire from an open but that is what I have going on between my factory harness and the Kufatec adapter.

Hope it helps

[DavidB8]

Thanks for taking the time I'm sure he'll appreciate it.

Hmm some oddities there for sure. Really not to sure what to make of Pin 14 on the chart. Pin 14 doesn't show wired in the schematics unless it's there for another type of car.

Some more info for those doing US light installs and the curious.

Halogen:
Pin 1 is Marker in US and Range control in ROW
Pin 2: Not used in US and Range control in ROW
Pin 3: Ground for Range control motor

HID:
Pin 1,2,3,4 left open on the HID are for the range control module that is used to self level the HID lights (In US and ROW lights)
Pin 13 is Marker light in US

Just so you can see what I'm trying to help him fix. Have pity..

Hi David,
This reminds me of the two 'members' (IIRC one in Germany, other in Colombia) trying to appropriate your ROW taillight coding some while ago.
Hope you get further with this mess than they did
Cheers,
Greg

Here's a couple pics... in case they help any (sorry my camera is old as dirt)

hey guyz
im having one more issue with the conversion
my pessenger side headlight is on highbeam and driver side is on low beam
please help someone
thanks

[ljnaum26]

Anybody save a copy of this thread before the pics expired? Im going to be attempting this install Ecodes next week and im little nervous because i don't really know how to use vagcom and see all these different codes mentioned. If you guys have any pointers on the install and how to use vagcom/which code to use let me know. Also is there a code to keep the running lights on when the blinker is used? thanks

Is this still the recommended coding? I have a premium 2009 without home link.

After conversion, you must change:

Module [09-Cent. Elect.]

Byte 0: From 69 -> 26 (for xenon lights)
Byte 2: From 00 -> 10 (enable LED DRLs)
Byte 14: From 7F -> 1D (bi-xenon highbeams)
Byte 15: From 5F -> 0D (bi-xenon highbeams)

[NPuter]

Yes, that is the correct coding. See my post here: http://www.audizine.com/forum/showth...=1#post4868137
The code for the DRLs to stay on with the turn signal is the normal code (posted in many places).

[ljnaum26]

Thanks for the response, i was just playing around with the long coder in vag com and its a lot easier than i thought it would be. The only thing im dreading now is running the wires for the high beams and pinning them. Theres really no pictures to help with that.
Thanks again

[ljnaum26]

This may help people who are unfamiliar with vag-com, you dont have to use the codes shown but it helps navigate the program. All credit goes to Essfive from the A5 forum for making the guide.

Once you get the knee panel and kick panel removed, you should see the red and brown/tan connectors where the pins get inserted. Don't try to force the pins in by pushing on the wire... you'll need to push directly on the pin itself with a good amount of force, so find an insertion tool or a small screw drive and you should be good to go.

[ljnaum26]

^THANK YOU. i dont know how i didnt see that post.

[Booya]

Guys need help. Got the bi-Xeon install and all lights working but the right headlight stuck on high beam. I check all wiring and swap ballast. Also getting bulb out when I turn on headlight

Never mind its was a bad bulb.

[nogoer]

I've been eyeballing this thread and upgrade since the day i picked up my A4 and realized LEDs were not standard. I got it used and have since schooled myself so yeah my bad. The only problem is now that lowesta4 only sells the kits for the 2013 models there is no easy way to get what i need. In fact i can't even find an inclusive list of all the necessary parts. Can any of you who have done this upgrade maybe detail out a list of at least the major and semi-major parts you need to do this? I have no issue with running ragged to locate everything, but i can't even do that without a checklist of what i need to find.

I thought the entire list was the following...
Left headlamp housing
Right headlamp housing
2x Xenon bulbs
2x HID ballasts
Kufatec wiring harness
VAGCOM to enable new lights

However i just a few minutes ago saw a quick mention of LED ballasts too. So im not sure i even know what i dont know i need.

thanks

That list looks about right now with your addition of the LED controllers, sorry don't have the P/N's though.

If you watch ebay.de you can find a complete set for a decent price. This saves you the hassle of sourcing individual parts (and prob some $ too) but adds the challenge of dealing with a foreign over-seas seller and increased risk of shipping damage... buyer beware.

[nogoer]

Thanks. I actually finally found a complete list a second ago while i was reading the vagcom codes section of the wiki. I get that you need vagcom to enable this upgrade but it's really an odd place for the diy parts list. I'm putting it here so that future readers dont have to hunt it out and hope they stumble on it.

Parts for this upgrade....

Hi guys.
I'm in process change halogen to xenon now. But i have problem with vag-com's coding.
my long code string now
690000B1013400000001000000005F5F411402080200000100 0000
if I change via vag-com cable byte 00 to 26 then i get error "out of range". But 09 block device number is 8K0 907 063 K
last letter is good for changing byte 00? Yes ?
If i try to change in service station via VAS then make it me good result ?


Early i retrofit my halogen projector to xenon by using morimoto lens - it fully shit, light is very bad.
We named it "farmer's xenon" (kolhoz ksenon in russian)
Next step is change to original projectors. but i have problem with coding.
May be my 09 device impossible to coding. Then i try to install original projectors with china ballast now i use.

[DavidB8]

From Australian Forum:

Yep..that is what Audi said..the controller in my car is 8K0 907 063 K and they have to order 8K0 907 063 D to replace it to activate the hi-beam and hence there is no error message jump up all the time

From Italian Forum

:09 This is a: 8K0 907 063 K and not good for xenon, has been replaced by one with the P final

From a French Forum:

and I thought that with my central "K" it would be possible...
What a disappointment ...

Gotta love that google thing.

[sao_ekb]

Thank you, David.
I will try to do it without coding. try remake kufatek adapter for high-beam pin stays as is, because setting up bit 4 of byte 02 converts high-beam wire to DRL wire.
Coding will stays as is. I need make deception for cold checking high-beam bulbs.
Maybe has anyone info about every pin function in halogen connector

Why don't you change Byte 00 to 23. That way the xenons will work properly. You just won't have high beam.

Don't think the parts # for the headlights are correct.

8K0 941 029 D and 8K0 941 030 D are for the US (LHD)
8K0 941 003 C and 8K0 941 004 C are for Euro (RHD)

I bought mine from Audi and they gave me a choice between 8K0 941 029 E, 8K0 941 029 F(Left housing US spec) and 8K0 941 030 E, 8K0 941 030 F (Right housing US spec). 8K0 941 029 D and 8K0 941 030 D are no longer available.

[reytran]

This is amazing. Would anyone tell me where can I get the housing? I digged eBay but the only OEM I could find with LED curve light cost $1,500 which is crazy. Rest of the aftermarket only one in Europe has curve light, rest of them cost about $700 for both side without curvelight. Is there anyway I can find a better deal? Thanks

[LagO]

ive had my bixenons installed for a while now but i just decided to install the high beam wires...i ran the wires and all but i only have one high beam working...i think i might have stuck a pin in a wrong slot, can someone confirm where the pins should be going? thanks!

Look on your kufatec wires it should be mark with pin #. Or just connect your driver side to the brown pin 3 and passenger side to red pin 9. If it still don't work, your shuttle is probably stuck. I had mine stuck on the passenger. I took the bulb out, loosen the screws, wriggle it, and bang it a little to get it loose. You should here it click on both headlights when you flash your high beam.

Thanks a lot for the info, ill try it out once it stops snowing

[elscotto80]

So i got my xenons installed. Did the changes in vagcom but did not change the high beams as i have not wired them up yet. Faults below make sense. I am getting an error for left and right corner drl faults on the DIS. I have the corner lights disabled as noted below in my long coding. I have a 2010 Premium. Do you think the fault is related to not having the high beams wired? I was getting the fault codes for no corner lights but fixed it in vagcom and clearly it went away.

Any help is appreciated. Thanks folks!

Hey guys, some of you have PMd me letting me know the pics in the original post arent working, sorry about that. I am in afghanistan right now so once I get back to the states and my home computer I will try to reupload the pictures I still have.....glad to see this thread still alive and helping people!

[elscotto80]

Hey folks-

I ended up figuring out my issue. I changed the codes for highbeams to what they need to be for the xenons and the error messages do not appear for the sidemarkers. They are also disabled in vagcom too. Only thing left is to get my highbeams wired up.

Disregard my previous post, problems solved!

[M4ik3E]

Please consider my issue I am deffinately not the only one who changed 09-centr electr module

MODULE FOR HEADLIGHTS (09 centr electr) IS NOT THE SAME ON EVERY B8, so
I bought a new module for 09 centr electr from kufatec to make my high beams work
since my older module didnt have the pins 03-09 .
My led's headlights and high beams work perfectly now
but somehow my interior lighting isn't fuctioning correctly.
Internal lights are not operational when i switch them on and instruments are dimm.
No fault codes on vag-com
except
''02095 - component protection active''

[LagO]

Feeling pretty confident in making the switch through the information on this thread, quite an awesome page. Had a question that may seem stupid; however, will prevent me from making a severe mistake if not done right. When connecting the high-beam wires from the Kufatec adapter was there any need to disconnect the battery? I have seen a few posts on different threads and different forums that said to do so but if it is not required I'd rather not for the fact of information being erased, radio into possible safety-mode, and all the other unneeded issues that may arise.

Also, can someone explain the byte and bit in VAGCOM? For example, change byte 2 bit 4... cycling through the various bytes, will they have options for the bits? Like byte 2 has the box to check entitled Bit 4 (DRL active)? I want to get a good grasp on what the coding really means before I start messing around with this conversion. Thanks

[hk5ykw]

I recently completed this retrofit (using European-spec assemblies) and struggled for a few days to get rid of the DIS error, even though the high beams were already wired and functional.

The problem only went away when I changed the intensity of the DRL LEDs to 26% or higher, as described under "Adjust LED Brightness" in http://audienthusiasts.com/VagComEXLight.html

BTW, thanks to the contributors to this thread, installation was almost factory-quality. The hardest part was taking off the lower portion of the dash, as the upper clips are very tight, to the point you almost don't want to pull (pull horizontally minus 10 degrees, toward you). Thankfully no visible gaps of creaking after putting it back.

i dont remember disconnecting my battery. the long code is broken up into bytes (group of 2's) so starting from left to right, the first 2 numbers/letters is byte 0, the second set of numbers is byte 1 etc. in the binary code, the farthest # from the left is bit 0, the # farthest to the right is bit 7. before changing your long code, write down yor original code in case you make a mistake and want to revert back. do not just copy my code from the op since we may have diff options on our cars. once you change a byte, click on another byte before you click do it! (not sure if this advice is still relevant). i also wasnt able to use the long code helper so i just changed the long code. heres a good beginners guide to coding - http://www.a5oc.com/forums/a5-s5-top...e-newbies.html

anyways, the reason i'm here is b/c my right headlight went out. can vag-com tell me if its my ballast or bulb or do i need to take my headlights out and test it? would my ballast die before my bulbs? the bulbs i have are d3s 6000k replaced about 3 yrs ago. the ballasts came new w the headlights about 3.5 yrs ago. thanks
