Alright, my car is now approaching 80K miles. I think the Eibachs and V springs are taking their toll from vibration and pothole 'bangs'. Last week, I drove at night and could barely see the road. Then as I passed some trees, noticed they're all lit up! When I got home, I got the Allen head wrench and went to adjust them, and NOTHING! I think the adjusters broke and both headlights are now at the end of the adjustment stops (Full UP!). I'm sure the cars I'm following or facing, don't appreciate the full HID illumination!

Anyone else had this happen? I'm still under extended warranty, but will be out of town for the next two weeks or so. I won't be able to take it in until then. I was hoping for an easy fix (pull airbox, pull a cover off of the adjuster and snap something back in, etc).

I had that happen to me when I first installed my HID's, I over adjusted them and the vertical adjuster was stuck aiming up at the trees, thought I broke it but I just kept turn the adjustment screw in the opposite direction until it fell back in track and then it was fine, havent had a problem since.

Where is this adjustment screw? I'm just wondering because my left light is aimed slightly higher then the right one. I also installed new 10000k bulbs today and I was thinking I may need to adjust them, not sure till it gets darker.

EDIT: they are fine. I'd still like to know how/where the screw is.

When looking on top of the drivers side headlight for example you'll notice 2 holes. The top hole (right hand side of the headlight) has a white cone surrounding the adjustment screw, that is your vertical adjuster. The hole to the left of the vertical adjuster is the horizontal adjuster. You'll need an allen wrench (I believe) to turn the screws.

Exactly. And if you shine a flashlight down the holes, you'll see a graduated scale, with a center mark to give you a reference to which way you're adjusting them. Unfortunately for me, turning those screws now does nothing. I think something broke internally to the headlights, presuably due to the 'firm' ride over expansion joints, potholes, and speed bumps, with the Eibachs and FE4s. Time for a visit to my dealer. While the car has been great, the extended warranty has really come in handy!

Damn that sucks Ody, turning the screw in the opposite direction didnt fix it huh. Yeah good thing you have that extended warrenty. I'm screwed now, my warrenty ran out and I only got the extended power train warrenty. Now for all those little things I have to pay out of pocket and the stealership (as I'm sure you know) will ask for your 1st born as payment, hahaha... If anything major comes up I'll be joining that ever growing list of folks trading in or selling there CTS.

Yup, they're just inboard from the headlights. When you open the hood, you'll see some 1" holes. Look down (a flashlight may help) and you'll see the adjusting screws a few inches down. Look close and you'll see the small white graduated scale with a center mark, too. It takes a 6mm (if I remember right) allen wrench to adjust.
