Sure thing, for an A6 or S6, and what year grille surround would you like? I'm not entirely certain it matters as I don't dabble to much in the newer A6 platform, but let me know so I can go to bat in ETKA well informed.

RS6 Headlights are in...
Here is a quick preview photo and video.
I have finished most of the work to install the headlights. I elected to have my headlights (specifically, the LED DRLs) operate as they do on the RS6.. which involves a number of wiring changes. This means that they dim when the headlights are on, and also dim when the turn signal is selected, on the same side as the turn signal. Check out this video to see what I mean:
http://www.youtube.com/watch?v=atiOcEpukqw
I will take another video tomorrow during the day so that you can better see the lights without the saturation effect I was getting trying to capture it in the evening.
If you can live with just having the DRLs turn on at full brightness during the daytime, you can get away with fewer wiring changes, and I think you can do the wiring changes inside the headlight only. I say "I think" because I ran into curious wiring differences between my '08 and the wiring required for an '09+ A6 or RS6. There simply weren't enough wires in the headlight harness (vehicle side) to be able to properly control the LED DRL... to turn them on, +12V (power) is required at pin 10 of the connector, while pin 12 controls the illumination level with a pulse-width modulated (PWM) signal. On the '08, pin 12 is power to the DRL lamp, and on my car, there was no wire in pin 10 on the right side... only the left side had a wire going into pin location 10, but I could not trace it back to a matching pin at the central electronics module under the steering wheel. So I have no idea what that wire is for... it's not documented in the Bentley repair manual. I would guess the A6 shares this harness with some other model car (VW or Audi), maybe it gets used in another application.
Anyway, I will start a new thread with a full DIY, I took quite a few pictures along the way. If you go the same route as me (with full dimming functions), you will also need to get a few repair wires from your local VW/Audi dealer, so that you can re-pin the headlight connectors slightly. You also need to either buy, borrow, or make your own tool to release the pins in the connector housings, they have locking mechanisms that keep the pins from backing out without a tool.
Still remaining to do, I need to troubleshoot why I'm getting an auto-check warning for MAIN BEAM bulb out.... with the way I it wired, and the way I have the central electronics module coded (3, Bi-Xenon Headlights with AFS), it shouldn't even be checking for presence of this bulb -- that bulb would only be present with halogen composite headlights. Hopefully I'll get this resolved... I remember reading about a similar problem that someone over in Europe ran into. The engineers at Audi seem to have done some creative things here.

Wow, I can't believe how much of an amazing facelift those lights make. Really, I can't believe two housings make such a huge difference. The DRLEDs help complete the whole package too.
Very nice work!
Very nice work!

Hi! I have Audi A6 2007 with normal headlights (h1,h7).
It is posible to replace a headlights with new LED headlights from audi a6 2009? Connectors is not the same type. Can anyone tell me about that? or give me some circuit diagram to now how do i connect the headlights.
