**02SILVANT** · 09-26-2008 05:43 PM

I found some B6 S4 headlights in the classifieds and was wondering will they just be plug and play if wanted to put them into my A4, i currently have stock xenons and self leveling thingy. The S4 housings came of a 2004 and i have a 2002.

TIA

Are the S4's bi-xenons?

I asked the guy the same thing and he said they are single but as much as i know i think just about all S4's came with bi-xenon.

Not all S4s had bi-xenons: http://upload.wikimedia.org/wikipedi...04_Audi_S4.jpg

Yes, it's plug-n-play.

It depends.

Some 2002's used a different bulb. There is a DS1 and a DS2 and I can't remember which is the odd one. Anyway, if you have the correct bulb (the only way to know is to pull yours out and look) then it will be MOSTLY plug and play.

1. You may have to modify the back cover of the S4 housing to accommodate the access of the ballast plug. It's simple if you have a dremel, and not a big deal if you have a drill and a hacksaw. Once the ballast is installed, silicon and exposed areas just to be sure you don't fog up. P.S. you're new lights will fog up. S4 light are prone to this do the o-ring fix, then plan to do it again.

2. You will have to move one wire in one of the sockets of each S4 housing to match the arrangement on your stock xenon. takes 5 minutes. The sockets are the same, and you should take the extra time to mark where the wire came from and where you are putting it, just so that you can switch is back if you need to.

3. High beam bulbs are not the same in S4 as in stock xenon. I believe they use H11 bulb type, but can't remember for sure. Do a search and something will come up.

I started a writeup last year when I did mine, but never finished it. I unfortunately do not have time to finish it now, but hope that this gets you started. I have an 02 as well.

good luck.

If the S4 housings from the classifieds are the ones with bulbs and ballasts, then yes, they are a direct plug and play.

The only other thing of note, is that the back of the housings are very slightly deeper on the s4's are it is a pretty tight fit getting the cables to run to the right places.

550 is a pretty good deal for basically new housings that come with everything.

^^^Ya they are the ones for $550 from the classifieds with the bulbs and ballast.

Thx for the info guys!

Early MY2002 (manufactured before November 2001) used D2S bulbs with the 4G ballast. If he has this system, the housing will most likely require a modification but the cover holes will line up fine.
