    Hello, my WDB211 08 E220 headlamps are too high when on dip, dazzling oncoming drivers and vehicles in front. When I switch them on, they self adjust but too high. I can't find anything in the manual which tells how to correct this. Any help gratefully appreciated. Thanks.

    If you have Xenon lamps, this should just be a broken link on the suspension either front or rear if you look under each nearside wheel arch you will see the rod hanging down.

    I normally have a link showing this but cannot for the time being

    However, isn't there a manual adjuster on the headlamp for the OP to use for now?

    That's what I do to mine, especially as last time it was MOTed they adjusted the aim to finish about 10 feet in front of the car.

    Very important to set the angle with the engine running, so that the lamps have adjusted to their usual height.

    There is an adjuster: there are three hex sockets on the top of each lamp. It's the middle one that does dipped beam vertical adjustment.

    The mechanical adjusters are used to set the beams without engine or ignition on, this is then checked with engine running and any corrections done using STAR

    You can use the screws to adjust the beam manually with the engine running if you want to.

    First if both lamps have gone upwards then a link if Xenon.

    Of course one can but that's not the correct sequence

    It all depends by how much, why not check the links first on the suspension if both lamps are out

    Most definitely, no point in adjusting anything until one knows the system is fully functional.

    My post outlined the correct sequence for adjusting the headlights.

    Sadly all the talk of adjusting the lamps had no bearing on the fault, ant the talk of adjusting them is pointless at this stage.

    Until the OP comes back and tells us what lamps he has, though they must be Xenon for if they were vacuum they would be pointing downwards if a pipe was off

    Well, that's exactly what I've just said, thanks for confirming! ;)

    If they were halogen the OP would have the adjuster thumb wheel by the light switch and it would be detailed in the handbook,which, apparently the OP has looked at.

    Many thanks for all these replies and observations. I am pretty sure they are xenons, it is an 08 Avantgarde. I will look for the links under the wheelarches and see what the score is there. Will report back. And thanks again.

    PS - there's no thumbwheel adjuster near the light switch...does this give a clue?

    No thumb wheel means xenons

    It has to be a leveling problem with both lamps out of line, you could turn do a quick check by either asking any MOT station or if you have a level piece of ground with a wall or fence at one end. just park a few feet from the wall and turn the headlamps on dipped beam, mark the height off, then reverse back about 20 feet and the beam should be lower

    Headlamps fixed

    Hi, finally got the headlamps problem fixed. My independent Merc specialist SPR Autos Ltd, Stockport, diagnosed and found a rear suspension levelling linkage hanger - I think that's right - had snapped, telling the sensor that the car was 'nosediving' - so it was pointing the xenons up all the time. All sorted and good service. Hope this helps someone else in future. Thanks for all the comments. :cool:
