    Hi all,

    My new toy outside has the near side headlight beam directed about 2 foot in front of the car and when I turn on the motor etc. in the dark the lights fire up and only the off side one runs through it's 'up and down' cycle.
    Does anyone know whether this motor (which appears to be at the back and bottom of the light unit) can be lubricated, needs replacing or just walloped with a mallet or something in order to make it function again!! Answers on a postcard to 'Edd1968's new toy's things to put right list'

    Thanks

    Perhaps the Arm has come adrift where it attaches.

    They attach to the upper control arm on a w211, Unfortunately im sure on a c209 it will look summit like this

    I think the OP is enquiring about the adjustment motor inside the headlamp unit. One failed in my CLS and I had to buy a complete new headlamp.
    Sometimes it's the little plastic link rod inside that falls off or snaps, which might be repairable.

    That's exactly the adjustment motor I'm referring to. Wish it was the sensor you showed Gav

    I had this issue many years ago with ours. I was anticipating expensive repairs but the Indie (Jack at PCS in Horndean) took the bumper off, reattached something and its been fine for the past few years. Apparently its not an uncommon issue. Unfortunately I can't remember exactly what had come adrift.

    Well it's definitely not cycling through its entire movement up and down when first switched, on therefore I'm assuming it's either seized or the link you mentioned is disconnected. They are silent so it's not like my Streetka with a motor wurring away to adjust them.
    I've manually reset the height to match Mrs Edd1968's lights against the wall (there are advantages of having 2 of these wonderful cars on the premises ;) you know) Just need to restore the lenses now as they're pretty yellow and tarnished. I love that job as the results are always great to see when you look at the before and after pics.
