Thanks.

I really don't think you would need that harness if you have vag com.

I am sure simply hooking the LED to the sidelight and turning on DRL in the MMI would be enough.
Have you tried that??

I should add that coding for LED in vag com is probably nothing more than adding the DRL option is the MMI and telling the bulb out warning indicator not to expect a draw on the DRLs as they are LEDs.

That harness looks like it bypasses that, nothing more.

With the Bi-Xenon headlights, the DRLs are not part of the sidelight circuit. Wiring LEDs to the sidelights and switching on DRLs in VCDS will not light the LEDs.

It's possible that a pre-facelift A6 with Bi-Xenons will run the LEDs as DRLs through the same circuit that currently runs the halogen DRLs. There is an option in VCDS to code the control unit with LED DRLs.

The control unit suggested earlier may only be required if you currently have halogen headlights.

Just guessing though. I'm sure someone far more knowledgeable than I will correct me.

Cheers
Dave

It can be done. Our colegues from Germany did it. The answer is simple. If you use the RS6 headlights and the bordnetz with the K version everything will work just fine. You can use your existing wiring , only some unpining will be done at the bordnetz. This weekend I would make the modification myself as my headlights have just arrived today. Prior to that you should go to an AUDI dealer and mount the bordnetz STG, because some CP will be activated.

Hello from Spain friends,
I am in the same situation
I want to install in my car the complete front facelift 2009
But I have doubts in the electric installation of the headlights.

And another great doubt that I have:

Do I have in my car headlights what a bi-xenon.
Should buy the empty bi-xenon facelift? (and to use the rest of pieces of my current bi-xenon, bulbs, starters, etc)

or should I buy the complete bi-xenon headlights facelift?

Tks ;)

I got a new Audi A4 headlight with LED today.. will get my used A6 headlight next week I think and then I will start playing with them.. For first I shall try to fit a A4 headlight into the A6 house.. next step if that wouldnt be goof I will take a couple of S5 headlight and try!

SO I have instaled the headlights on saturday. It's recomended to install the RS6 headlights as it's much more easiear to adapt the electrical wiring. If you have AFS or not you can just order RS6 headlights with or without AFS. You just only need to order the headlight housing. The old afs and bixenon module , D2s bulb can also be used. You also need another lights ecu onboard supply, do some unpining , make a VDCS coding and voila you have it. If there is interest I can provide you the PN numbers required for the modification.
Not last for this modification we've got to thank to our colegues from GERMANY, the motor-talk users. They have provided very important info's and instructions so I think that it's right to give them all the credit. I'm just a messenger, I folled the instalation instructions and make them just a litle bit better. Till then I'll give some pictures with the beast.

Hi! What u mean with "lights ecu onboard supply" what u changed for that? And tell me wich pins please!.. then I guess no extra controller for dimming etc is needed?? right?

I now seen on the pictures that u didnt using ur halogen lamps now.. is it those pins u changed or something for LED instead? and LED is working with Xenon on to I saw.. nice! Give the pins layout and VCDS coding to please! Looks nice ;)

The car has been fantastic

Yes, please.
Explain to us like one makes (how-to) and the references of the pieces that you have used.
Tks, regards

PD: you could give me information (PM) of where you have gotten the headlights.
