I can't remember top of my head but this thread has all the info you need.
Go back a few page and you'll see.

Got them fitted, everything is working other than high beams. My module has an m suffix, it's a 2011 rhd uk model. I have had to use 23 in byte 0 as 26 is out of range. I reckon there is another code for the high beams when 23 is used but it hasn't been discovered yet

No, you have to replace CE module.

Mostly what I've heard is they laugh and tell you it can't be done and that when you buy your next Audi you should just get the Prem-Plus or Prestige package. I don't imagine it would be cheap. You'd have to buy factory Audi housings, factory Audi bulbs/ballasts, and then there's the high-beams problem which requires you to get the kufatec adapter which is probably where Audi washes their hands of it and says "Nope." I don't know whether the default light inputs are changeable in the ECU, but the fact that you need an adapter as well as vag-com codes suggests to me that there's no actual Audi-factory way to turn OEM Halogens into Bi-Xenons, and if there's no official Audi factory way to do it, they just won't bother trying.

Even if they could, parts alone probably puts you well over $2800 if we're talking Audi factory parts and the typical markup of dealer prices. Factor in labor, and I feel comfortable saying it would be $4,000 before they were done. I guess that would be $2,400 GBP. That's some serious coin. If you don't want to do the conversion yourself, I recommend acquiring all the parts yourself and paying a local shop (that knows what they're doing and has a vag-com) to do it.

[turboblade]

No I already have everything done, other than replacing the module. That looks awkward, how much do you reckon they'd charge for that

To be honest I don't understand why I can't use the same wires that were used for high beam previously to open the shutter. I am led to believe these wires are now used for the led DRLs. Why is this? Why can they not use the same pins as the halogen DRLs

They're different wiring harnesses...that's why you have to use the adapter. Different amount of pins on the connector for the HID lights

Hello,

small contribution to the TOPIC.

I have done the conversion from halogen to bixenon on the stock Controller: 8K0 907 063.
First of all, enabling the bixenon by changing byte 0: to 26 <--- this is impossible with VAG, but there are specialized shops who have above standard cables+software for coding and one of these shops was able to change the hardcode from 69 to 26 = BIXENON ENABLED
Next is to enable LED <--- this was easy as for anyone else

So how about high beams?
Kufatec adapters run 2 extra wires that control the high beam "flap" in the headlight. These wires are to be connected to the pin #3 and pin #9 on the Red and Beige connector that is directly connected to the Control unit. So what happens when I connect them and enable coding ? NOTHING. So let's see why. (sorry for no pics).

RED and BEIGE cables are Left and Right headlight running to Controller unit. That's ok. We added new cables to the RED and BEIGE that will control the flaps of high beams, so that should work with the correct coding. But it doesn't because standard unit's sockets (for RED and BEIGE cables) doesn't have any pin leading in to the #3 and #9 pin position in the connectors of RED and BEIGE cables.
That is the only reason.

So everything is possible, but who would modify the controllers ? I won't.

Conversion with basic controller:
PROS: we can enable bixenon + halogen just fine.
CONS: no LED brightness adjustment, no LED dimming when turn signal on (led turns of for that time), no high beams

Btw: I have done the conversion without KUFATEC adapter. My electrician re pinned the original connector in 30 minutes and it was working properly exactly as with KUFATEC.

I know this doesn't help much, but maybe some1 is fine with running his lights like this and he has stock controller.


p.s: I have new controller with suffix P on the way home so will keep you posted on how it went (no plan to visit audi dealrship for unlock)

So if I plan to pay upwards of 1000 to change my headlights from halogen to bixenon I can not use high beams and can not keep my leds on while turning signal on -.- why bother

I spent $800 and can do both of those things. Reread the thread....

I'm just gonna say this and leave.
I spent 1500 CAD (bought Ecodes) for this conversion (diy), and it was worth every penny.
Seeing that LED light up at start makes sooo much difference than halogen.

I'm not sure why people are having issues with high beam.
Get kufatec, wire them correctly and code in right, and you will be set.

the kufatec do I order just one cable?? and the led ballast and everything cost about 400 is that a fair price?? and still looking for the headlights -.-

One order of kufatec (~$100) comes two cables.
And yes, pair of ballasts and bulbs cost around that, though you can find used ballasts for cheaper.
Headlights (non ecodes) come up on classifieds quite often...

is 900 a good price for ecodes?

I think so - that is precisely what I paid for a pair (used, but decent condition).

I think that is a decent deal my friend.
Just make sure the manufacturer is either OEM Audi or Automotive Lighting (who are suppliers for Audi headlights).

Not sure who they are but if the reviews are good.. You will be ok..
Oem audi and AL make ecodes too... For europe.

Need some help guys, my mechanic is giving me grief because of my high beams and won't pass me for Pennsylvania safety inspection.

Everything works except for pushing the light stalk forward to get the high beams to remain on. The backward stalk flick and forward stalk flick both cause the momentary toggle of high beam activation.

He won't pass me because the forward stalk flick does not cause the expected behavior of the beams staying on.

I've tried changing byte 14/15 to:

1D0D
5D5D
3D0D

All with the same result.

Any suggestions?

What year is your model?
This is my actual long code: 26001031063C00010000080000001D0D0F1452080000000100 0000

You might want to try changing the entire long code...
You can always revert back.

Same model as mine, so that may work... but don't quote me on it.

Newbie here Guys with another Successful Conversion I completed back in March. All Thanks to this community. It's been aprox. 6 Months. I did Use Aftermarket Headlight housing from ECSTuning Brand TYC. Total cost a little over 1000.00



Here are The steps I used. Alot from this Forum and some input from others. STEP BY STEP INSTRUCTIONS

[coolwater]

Anyone know if you can fit an afs light even if your car cannot support it? Is there a code in vagcom to disable it? Will the lights still work like non afs?

Curious if anyone installed afs as part of the conversion.

It won't work at all, ecu won't recognize it

Hey all. Did my retrofit today, thanks for the info ASU Daniel and NPuter! I am getting left and right DRL errors and I also can't figure out how to code the high beams. So far I enabled the xenon low beam and DRL's with no issues but I'm not sure how to do the last 2 coding changes in VCDS. I'm a bit of a noob using the software and I'm am not sure how to change the bytes to 1D and 0D. Can anyone point me in the right direction?

Byte 14: Change to 1D (bi-xenon highbeams)
Byte 15: Change to 0D (bi-xenon highbeams)

Just delete manualy 7F5F in your last picture from top line "1)", then enter there new figures, exit and "do it". First security code as usual. Hope it helped.

Thank you Gunnar! That makes total sense, up until now I have only used the long coding helper. Will give this a shot today and report back.

Finally got the conversion done and am curious if I've got a problem or if I'm just overly worried. When I first turn on my new xenons I get a quick bright flash that's a little red and then they quickly settle in to steady light. I've done the coding and I don't have any flickering and the lights stayed on for an hour drive with no problems. Is this normal?

It's normal that it first turns brightly with a different hint of color (I'm not sure about red though), then settles to the normal 6000k or whatever you have on.
If it runs fine once settled, and there are no codes, I wouldn't worry.

hi
I have recently done my conversion, dunno if im writing in the correct thread, sorry if its wrong.
I have a 2009 a4 tdi se (UK, halogen lights) I have just converted the front end to the b8.5 having a few problems, I have read through this thread and it has solved a few things, when I 1st tested the lights drl worked on 0, auto main lights turn on, side lights nothing came on and main lights turned on but sometimes flickered. so I tried to do the coding byte 00 from 69 > 26 but wouldn't allow me to do it said error 31 out of range but looking on here I have changed now from 69 > 23 and I have not had no flickering so thank you for that, also changed byte 2 from 40 > 10 now drl come on on auto but when it gets dark they turn off and the main light comes on. basically my side lights are not working. I have no connected the two extra wires yet I was told they were for high beam which I know I have to buy a new control module as mine is ending with letter K and a lot of ppl on here have said it does not work which would explain why I cant use code 26 or change byte 14,15 for the high beam as they say out of range. would the wrong module have something to do with the side lights not working?
would be grateful for any help
ps I have changed the back end last year xmas and that all works fine

hi
forgot to say, I scanned the control module for faults and only two come up are relating to high beam nothing on the side lights, when I start the car everytime dis comes up with right and left side light /drl error
cheers
