This is from the Audi A3(8P) forum.
They're having a problem adjusting the xenons in lowered A3's; as the lowering seems to be tilting the auto levelling sensors.
1. Is anyone with a lowered GLI having this problem?
2. For those of us planning on lowering their car, is this what we have to do to recalibrate the sensors?
3. (Slightly off topic) I read somewhere that if you have the alignment done, the dealer needs to have the steerings electronics zeroed and recalibrated after the alignment.
Can someone explain #3?
Here's the link to the A3 post:

Re: Do we need Xenon adjustment for GLI's with lowered suspensions?? (Just4u2c)

Xenon height adjustments are made using an alignment tool, then programing the car using a VAG-COM or 5052 to set the lowbeam level. Seen it done on W8's.

Re: Do we need Xenon adjustment for GLI's with lowered suspensions?? (06DeepBlack)

When I lowered my car the auto-leveling became non-functional. No CEL was thrown nor were there any DTCs. However, when I scanned the auto-leveling module and tried to complete the VAG-COM adjustment procedure, I found out that the front sensor was out of adjustment range. I had to drill a new hole in the bracket that holds the sensor to physically position the sensor lower on the bracket. It's maybe 3/4" lower and it put the sensor right in the middle of its voltage rating thereby making the auto-leveling functional again. Honestly, the procedure to aim the Bi-Xenon lights isn't nearly as complicated as one might think. Simply, you have to put the car on a level surface with a gas tank that's at least 3/4 tank full, log into the leveling module via VAG-COM to "zero" the lights, aim the lights and then save the settings via VAG-COM. VW doesn't provide for any adjustment on the sensor itself, by the way.

Re: (jettaproblems)

I'm having problems.
I can't log into 55 or 29 for the controllers and then basic... it stops on 004, something no adjustment permitted.
Under 55 i do get this:
Quote »
VAG-COM Version: Release 512.1-UD
Control Module Part Number: 1T0 907 357
Component and/or Version: Dynamische LWR 0003
Software Coding: 0000003
Work Shop Code: WSC 00066
1 Fault Found:
01539 - Headlights Not Adjusted
005 - No or Incorrect Basic Setting / Adaptation

Time for a custom bracket? And I'm just on Neuspeed sports... ugh!

Interesting, my GLI levels just fine despite being lowered. I can see them aim down and then level.
In fact my cutoff is still right at the trunk line of cars I'm following.

Ummm, that won't allow you move them up or down. Mine still goes up and down when you turn the lights on.
But you can't adjust them, supposedly the sensor is out of range when lowered.
I think the only way is to make some new custom brackets, or fab up some new shorter "rods".

I would assume yours work fine because your running 19's maybe? with that combination the car cant be sitting all that much lower to the ground than stock. Does that sound correct?

Re: (IchBinDarren)

^^^
A arms are still compressed the same, no matter how large or small the wheel is.
See the pic I posted above, that rod will need to be shortened (in my case front 1.2" and rear 1.5"), or the brackets will need to be bent or new ones fabricated. That will get the sensor at the top of that rod back in "range".
Once that is back in range, you should be able to do the vag-com procedure to adjust the lights, then set that adjustment in the ecu.

That shouldn't make a difference; when running 19s, metal replaces rubber. The overall size of the wheel (rim and tire) should always be the same. Otherwise, the speedometer would be thrown off.
Lowering the car shouldn't affect the leveling of the HIDs unless the rear was a lot lower or raised than the front. Especially when the drop is modest (i.e. not "tucking")

When mine was done, the dealer crushed the sensor. They ordered a new one and all is fine. I didn't exactly understand this cause if it would crush under spring compression....why wouldn't a loaded trunk do the same? They replaced it and didn't charge me a dime so I was happy....

Re: (GaBoYnFla)

I'm going to get under there this morning, but if you look at the sensor with the car on the ground, It's all the way up. That probably explains the error code, and the failure to manually adjust them.
If I used some RACE springs, I'll bet it would have snapped off under normal compression of the lower control arm.

I wonder if the European GTI suspension has a completely different bracket for the sensors...

Re: (BRM10984)

You can use a pry bar to move the front sensor up.
The back is a little trickier, I just tried bending it up but it's really close to the exhaust, so I hope it's enough.
I'll scan for codes later and see if I can recode to reset the headlight aiming.

This is true...
Ive had no issues with mine either, and I believe I was one of the first people to install coilovers on my GLI. As low as Ive been, Ive yet to have any serious issues. They are a little low for my liking, I would like to have them tilted up just a hair higher, but they adjust fine and afaik have no error faults. Im going to have to get a hold of a VagCom at some point and see if there is anything.

You should scan for codes on the xenon controller (55) before making assumptions!
