I have a B5 A4 with xenon headlights. I think that they are aimed really low. I searched the forums, and it seems that I might need a VAG to aim them (cause you have to tell the motors to reprogram themeselves). Does anyone have any tips/care to help me aim my headlights? =)

is over designed and basically unneeded. It has added one more point of complexity to what should be a simple system. On my 99 I took it in seveal times to get it working properly. The 02 I've done the same and have thrown up my hands in disgust.

aiming using the white hex adjusters on the housings and it has been fine.

<i>"This procedure details how to perform a Xenon Headlamp Adjustment on many VW/Audi vehicles equipped with Xenons (HID's). This procedure cycles the motorized headlamp adjusters to their center position so that the beams can be adjusted. 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."</i><ul><li><a href="http://www.ross-tech.com/vag-com/cars/xenonalignment.html">http://www.ross-tech.com/vag-com/cars/xenonalignment.html</a></li></ul>

Just did this with the A6 over the weekend. Basically, the adjustment is manual via a hex key. However, since they have little step motors on them, the motors don't recognize the new position as their "home" position and therefore throw a code. Hence, a VAG-COM is necessary to put the motors in a "learn" mode to accept the new position.

There's a writeup for it on the Ross-tech site.
