No de-tango as going to go tony's route and get a pair of these new ones as i cannot fix this one.

Not sure I'd be any wiser on retro-fitting adpatives onto a car without them, but I'm thinking should be possible, just the control unit part No.s would need to be checked.

Next time mine are off (still not installed properly) will jot down the part No.s

the control unit part No.s would need to be checked.

What I also said in a PM to scaghead...

On VCDS the control units show up with "AFS" in the description, so I reckon they would need changing too.

Ballast/control module under headlight unit



VCDS reading of Xenons

I have a receipt for my car stating ballasts were replaced (06 car, 09 dated ballast) 8E0 941 329 A which ETKA says superseded and replaced by 8P0 907 391 for adaptive, non-adaptive is listed as 8E0 907 391 B

4F0 910 357 E - refers to range control module (one behind dash/in boot ? ) ADAPTIVE (now listed as 4L0 907 357), 8P0 907 357 H for non adpative.

At a guess both need replacing ??

cheers for the research fella,looks like you have saved me taking a gamble and fouling big time...seems like it would become to expensive to do really...thanks again

You were spot on dave,thanks fella

No worries, I'm sure you can live without adaptive

[scaghead]

Good point fella,have a few drinks and it will look like my lights are turning into the corner....

So basically if I go adaptive not only will I have to get the lights but three ballasts as well...another

Ok, so I managed to get the new OEM headlights fitted on Saturday. I can confirm that all the bulb holders are present in the lamp housing so it's simply a case of swapping over the xenon ballast unit and xenon bulb from the old unit (2 minute job). I also transferred my bulbs as I have PIAA DRLs.

Btw anyone know if I need to do some sort of alignment (horizontal) procedure now I've replaced the headlights? vertically is dealt with by self-levelling unit I think and that seems to be working fine (dances up and down on startup and they seem pretty flat shined against a wall).

Here's some pics (Sorry, like a nob I forgot to take a final picture of them fitted, but will do as soon as the snow clears!)...

Main reason for replacement - tonne of moisture in passenger side lamp housing:



Close-ups of the ballast unit (non-AFS) with part numbers etc:







While the bumper was off, I hammerite'd the oil cooler connections in an attempt to slow down corrosion. These are the before pics:







It's quite hard to get even a small brush in between the pipes etc so it's a mess of a job, but think it will help a little:

glad your swap went ok.

yes you have to do a setup sequence, see ross-tech

interesting, your ballasts dont seem to have an Audi part No. ??

Hrm, "This does NOT align the headlamps by itself. You still need to manually adjust the headlamps via the adjusting screws as referenced against a suitable aiming target."

Can't find anything on Elsaweb about it.

Yeh, it looks like the ballasts are OEM, maybe the originals were replaced at some point.

['R'e'S'pect_4]

i think you need to set up initial alignment and then tell car that that position is 'normal' and it will set its alignment to suit.

Yes, that is what I had to do with my Golf when they were too high - tell the car you were going to adjust them, adjust them with the screws then tell the car you had finished. The were a lot more basic than the Audi ones (no dancing whatsover) but did have some sort of auto-adjustment as all OEM Xenons have.

Great job - how easy was it to swap the bulbs/ballasts over - you said 2 mins - would the headlights need to be out to do this & were the bulbs D2Ss did you notice ?

Out of interest, how did you decide you'd got the right height? is there a known process for aligning them against some sort of target to get them at a certain height over a certain distance for example?

Very easy, just plug the bulb in. The ballast plugs into a space underneath the light unit and there are 4 x T25 (iirc) retaining screws. Seriously, 2 minutes. It's not possible to change the ballast or even the xenon bulb though without removing the headlight, and therefore removing the bumper. Grr.

I didn't notice what type of xenon bulbs they were sorry.

On main beam the headlamps should be aimed to point straight forward and angle down at 1.5 degrees.

So find a level piece of drive, car park, WHY,... with a fence or wall then park right by the wall, then turn the headlights on main beam and mark the centre of the beam pattern on the wall. Then reverse straight back a known distance, the centre of the beam pattern should now be vertically below the marks you made and 1.5cm lower for each metre you are away from the wall.
