I do not see 3 adjustment screw on my 06 E320 CDI. There is only one screw visible and it adjusts height of low beams. My high beams need to be lowered but I can't find any visible means of accomplishing the task. Even searched in my FSM and can't find the procedure.

The allen adjustment ("B" in the craftysince86 pic) should adjust both the high and low beams together at the same time. Counter clockwise is higher. At least that's the way it is on my 05 CDI. On my new to me car (two weeks now) the passenger side headlight was aimed way too low and gave poor light. It turned out the bulb was not inserted properly into the projector. It was actually quite tricky to put the bulb in and twist it into the locked position. In addition just inboard of the larger cap which covers the bulb is a small off-white cap which holds the projector in place. Mine had come loose and I had a struggle to figure the system out and put all the parts back to the position which they were designed to be in. Eventually I did so and the lighting is now fantastic. I started a thread on it here- you can see the pics of what I did.

I believe your high beams and low beams are adjusted at the same time via the single allen headed plastic adjuster. Have you tried that and it does not adjust the high beams as well?

I put HID low beams in and after adjusting them, the high beams appear too high.

So you've altered from stock the low beams to HID and now there is a different beam pattern- and that beam pattern when adjusted for the low beams causes the high beams to be too high. I think the problem is not adjustment but the alteration to a different than stock unit.

If you search my profile and threads I've started there is a thread about my headlight issues from just a bit back- maybe one month old. My passenger headlight was misaimed and I thought it was me- but it was that my bulb was not fully inserted into the projector. Next to the lowbeams bulb cap is a white cap which I believe holds mechanism which ties in the low beam to the high beam. Perhaps removing this cap and it's arm may allow you to change the up/down of one and not the other.

OK, I took a couple of pics of my old headlights to help you out:

Upper photo shows the back of the headlight.
Lower photo is a close-up with crude outlines.

The 3 Torx screws to remove are circled in blue. The bridge piece is outlined in yellow. The "single" elevation adjustment is in magenta. For orientation, red is the high beam and green is the low beam.

Remove the 3 torx screws and the bridge piece. You will now see another adjuster at the left end of the bridge that was hidden by the cover. This will be the vertical high beam adjuster. Without the bridge connector, the two vertical adjustments (high beam and low beam) will be uncoupled and you can now adjust them separately.

What is behind the lower white cover in the top picture? What is it's function- thanks for the details!
