C320 Xenon headlights adjustment
 

Have xenon headlamps on C320 (2001) .... lamps replaced February 2008. Everything fine for over a year, but now notice that they seem to be shining too far down (ie. not at a high enough angle thereby limiting the visibility area) .... & need to be adjusted upwards.

Are these self adjusting (something gone awry?) or is there a mechanical screw adjustment that could be done ? Can it be done easily or only at dealer ?

Anybody know anything about these ? Thanks.

xenon light bracket & exterior temp sensor
 

In case others have similar problem, though noone seemed to reply ... decided to go to dealer. He found that the small bracket at sway bar attaching a small pivot arm from sensor was broken. Hairline crack through, probably from hitting a pothole or stone, etc.. With pivot arm loose, this meant that the sensor could not read level .... rear suspension bracket arm attachment was still OK. Front bracket will be replaced for about $30. As well replaced the exterior temperature sensor behind bumper (rhs, passenger side, accessible from underneath by removing a couple of screws & panel) ... again $30. Dealer was very helpful.

Same problem with my car the light gets dim when i start engine i am planning to get new HID kits just searching each and every offers
