How To: Audi A8 Xenon to LED Headlight conversion!

/ solveelectronics
I finally got around to fitting the LED headlights on my 4H A8 and they work great! I highly recommend doing this!
Control module with LIN (others are available): 4H0907063CG
Coding:
New coding for 09-Cent-Elec: 0067E03909348FE3AF810007E0000000CF9CC30806000141800108640F01
New coding Headlight modules (both): 110000
Deactivate Bit 2 in Byte 0 in 85 camera
Remove 55 range control from 19 gateway
Turn off adaptive lights coding in 17 instruments
Wiring:
LEFT
from xenon plus - LED from to j519 for info
12T17c DRL wht already connected
7T17c DRL orng already connected
15T17a Main LED already connected
5T17a Indicator already connected
pin 8 NEW WIRE 12T17a High beam NEW WIRE
8T17a fan already connected
pin 11 move to pin 14 rmv from 3T117a 1T16c-LIN RE-USED WIRE
RIGHT
pin 11 move to pin 14 rmv from 11T17c 1T16c-LIN RE-USED WIRE
pin 8 NEW WIRE 2T17c High beam NEW WIRE

Wish I was able to do this to mine. Sadly I’m not that good with computer programming and coding all that

hello, I saw that the headlights he installed are American :) I bought the same ones and the module for them from the same car. If we follow the steps from your video, will it be possible to replace them with the factory ones that have xenon on a European car? Greetings from Bulgaria ✌️

[@SolveElectronics]

These are European lights

hi, thanks for.the all infos, it really helps a lot. but i have missed something. "pin 11 move to pin 14 rmv from 3T117a 1T16c-LIN RE-USED WIRE" could u expland more in detail whats this means.

[@mr.sandnes9257]

Is it possible to do this with only the correct BCM and coding?

[@SolveElectronics]

Even if you have the correct bcm, wiring will need to be done

[@tihomirpopov3092]

Hi , the wire from the head lights ( hidhbeam )witch pin have to be connected on silver 32 pin connector. Thanks

[@SolveElectronics]

Hi, please see the wiring diagram in the video and the connection table. You will see what needs to go where as everything is there. If you have different wires, it can be that you don't have a similar setup, or, that you have a US spec vehicle which this video does not apply, since I do not know those vehicles, but I assume it's not much difference

@@SolveElectronics Hi, after installing the new module i got with the headlights .. the turn signals are half lit, fog light not work and the display in the odometer lights up very dimly. Should the protection component be removed? or do you need new codes? On channel 55 headlight range no access !

​@@tihomirpopov3092You didn't watch the video did you?

[@GravityEgg]

pin 11 move to pin 14 rmv from 3T117a , and then do what for 1T16c-LIN, and RE-USED WIRE from 3T117a?

[@SolveElectronics]

It means that pin 11 on old headlight has moved to pin 14 fir the new headlight, so, remove the wire from the connector 3t117a to position 14 from position 11. Because we moved the wire, it is re-used, not made new. For Lin wires, we make 1 wire and split it into two so that it connects to both headlights, and it's connector in the car where It should go is 1t16c-lin (pin 1 on socket t16c)

Hi, your video is very helpful, thank you. But I have an error that I can't get rid of. The error message is "adaptive light system malfunction". Could you please help me with resolving this error?

[@SolveElectronics]

It's most likely either the adaptive light controller, it ther motors themselves within the headlight. It could be one of the connectors on the light has corrosion or broken wires inside, this is also quite common

[@melisaljubenovic5478]

@@SolveElectronics Thank you so so much! My issue has disappeared 😊. I have one more request, if it's possible for you to remotely access my computer and check if the settings are correct, as I'm not sure if the fan inside is working. I'm willing to pay as well 👍

[@SolveElectronics]

​​@@melisaljubenovic5478you're welcome. I could check, but I can't do it remotely because I don't know your vehicle, and I would need to see what works and what doesn't etc. If you have an A8 I could try remotely. If you're local to South Germany or Switzerland then it's possible on site

[@melisaljubenovic5478]

I am from Salzburg and drive an A8 built in 2009 with fully Equipment and have exactly the same lights.

Hi. I was hopping to get some help about component protection in J519 ( BCM1 or power control module as you call). How did you remove ir? The eeprom change didn't work?

[@SolveElectronics]

It's possible to change the main processor and this would work but it's better to do it by the dealer. It's not expensive, but can also be done with vas5054 and Odis

[@tariktokalija452]

Are these matrix LED headlights? Does the matrix system actually works? And are new headlights OEM or aftermarket?

[@SolveElectronics]

These are not matrix. Matrix was introduced on the facelift version

[@tariktokalija452]

But they are adaptive? Automatically switching between high and low beam regarding oncoming traffic? @@SolveElectronics

[@SolveElectronics]

​@@tariktokalija452 The LED lights that I have installed are not adaptive in the first generation of LED headlights. Only the matrix lights are adaptive, and the adaptive xenon lamps

[@tariktokalija452]

thanks for response@@SolveElectronics

[@PsiCHou21]

Hi, how you adjusted lights ? Is it done by coding or just with screws ?

[@SolveElectronics]

It is done with the screws

[@Jirihajek-e8v]

how much money will it cost?

[@SolveElectronics]

Sorry fir the late reply! Headlights were around 1500€ and light modules around 200 and cent elec module was about 80€
