w204 bi xenon headlight stuck

ummm so this happened and now I have adaptive headlamp inoperative and his beam assist inoperative warning stay on permanently. when the car gets turned on the head light adjusts up and down but not left and right it just stay in that position.

Ive found in thread off other sites for w211 and other models but nothing on this happening to a w204. I have no codes with a basic scanner, maybe need to get a star diagnostics is needed to fix this.

let me know what you guys think

(yes this is the duck headlight that was replace by insurance.... just great)

Hi,
How do you feel about removing the bumper and warming up the headlight with a blow heater then remove the perspex outer clear cover to expose the problem?
As I see it is is worth a look inside as it may be fixable otherwise get a used replacement.

I'm pretty handy but god anything electrical puts my confidence to a -5 lol. is there a way i can just turn the bulb back to centre??? I don't care to have the adaptive headlamps. My wife drive the car and maybe drives a handful of times in the night. Used head lights are well over $1000 Ive looked...

When I brought my 2008 W204 the r/h headlight was playing up and would get the adaptive headlight message in the speedo.

I worked out the p/n required and ended up buying a used one from Japan, which is still in the car 5 years later with no problems at all.
The reason from japan was they are R/H drive and price was very good as was freight.

On your old headlight maybe underneath there will be the p/n decal you will need this to start looking.

does anyone have an OBD2 scanner that can calibrate headlights? I'm curious if maybe a calibration would solve it.

I know the $1000 scanners can, but at that price the dealer star tool would be the cheaper option.

someones selling a Foxwell nt510 elite it shows a headlight option on the screen but don't have information on what it can do.

please let me know if your scanners can calibrate headlamps, thanks

well after taking the bulb and wiggling the control unit, hitting a bunch of pot holes it got unstuck LOL. I took out the rain/light sensor cleaned the dust, now adaptive headlamp inoperative and high beam assist inoperative is also gone.

Sorry i couldn't get a real fix for this, but im glad i saved $1500 not buying a new headlight unit. Rock auto has the housing for $1200 shipped, junk yards want $1250 plus tax.
