Hello, my right-hand side headlight's aim is very high, while the other headlight is normal..
When switching my fog light bulbs, I also discovered that the purple vacuum hose is not connected on the right-hand side headlight. After some research, it seems like this is not supposed to be connected, as it's only for cars with manually-adjustable headlights? (My left-hand side headlight has this vacuum hose/pipe connected FYI).
And yeah, it must be factory fitted Xenons, I don't have the headlight adjustment-switch inside either..
My scanner picked up this code for the right-hand side: B1001: Zero position adjustment has not yet been carried out or is not possible. What does this mean ? Could it be because of this vacuum pipe, or is it only regulated by the leveling-sensors?
Could there be anything wrong with one of these sensors, or would that result in both headlights aiming too high/low?
Do I need to get this headlight adjusted in STAR? Is this the only way?

If you have proper factory Bix fitted then the purple pipes are redundant. A high headlight usually means that the leveling servo in the light is damaged. Out of calibration usually leaves both Bix staring down onto the road just ahead of the car.
When you start the car with Bix on auto at night do they do the standard flip flop up & down & then settle? Check that both do this. This will confirm that the auto leveling is working.
You can also try disconecting the front and rear sensor arms at their tip pivot. NO NOT unbolt the clamp around the torsion bar on the front or will lose calibration. Then with the lights powered up cycle the sensor arms over their full travel a few times for the controller to relearn their parameters. Then reconnect them.
If none of this works you need a Star & a lightbox to recalibrate them.

Thanks a lot, I will try this when I get home, but it's not bi xenon btw... It is xenon in low beam and halogen in high beam. If that matters for the level adjustment?
Do you guys know where in the headlight the leveling motor is located? Is it easy accessible? Or do you have to like take a part the whole headlight?
Because I was wondering if I could unplug and switch over/test the left headlight motor in the right headlight? Or would unplugging this motor reset/delete any leveling standards/settings?
I was thinking of this just to make sure it is the leveling motor itself that is broken, before buying a new one.. Is this possible to check, without deleting any settings?
Also, I was looking at an upgrade for my car's look, figured these might come with leveling motors as well since it is for factory xenon? Don't know about the quality though.. Heard a lot of different meanings about the Depos..
In my understanding you'd have to open the headlight to get to the motor.
Looks like they are not bi-xenons though. I wouldn't assume stuff - message the seller with questions.
If you want to go OEM (OES?) bi-xenon I had a thread about these on ebay: https://mbworld.org/forums/c-class-w...ghts-ebay.html

Ah, is it a lot of work? I couldn't find any tutorials for it... blah.
And are you sure I have BiX? Because I do have a halogen light bulb aswell, in the high beam socket. I thought this was something that Mercedes started doing before BiX? And was called Xenon only.(?)
From the eBay description: This is for with stock xenon models, the headlight has D2S HID low beam housing, so it's direct transfer of the stock xenon system (bulbs and ballasts) to the headlight.
Search for projector retrofit threads, there are some tutorials on opening the headlights.
You probably have [non-Bi-] Xenon. Are your headlights frostys?
I was pointing out that if you are buying projector headlights, might as well go with BiX...
All the OE W203 headlights have the halogen high-beam bulb. Bi-Xenons move the projector shades down AND turn on the high-beam halogen lamps for super bright high-beams
Okay, I was able to adjust the headlight down to the same level as the other headlight with the adjustment screw. So now they are equal when standing close facing a wall, but whenever I start driving /stand far away, I can see my right beam being a lot higher than the left one. Seems weird? What does this mean? Looks like the right beam is correct sometimes, but isn't quite following/loses calibration at distance (?)
And yea, my headlights are frostys /the blurry ones. (non-clear). It looks like the headlights are doing their dance at startup.
Have you adjusted the level with the car 25ft from the wall?
Try to disconnect the self-leveling connector from the headlamp, that way it will not try to readjust itself. (I am assuming they don't specifically test auto-leveling in EU and you just need the lights to aim +- straight)
