searched all over rollbar not lowering after bumps HELP!!
ok guys I have looked all over and cant find the answer, the w209 has a manual release but not the w208. the top is up so its hard to force it down, even with 2 strong men. i tried pressing the switch for 20 seconds but no luck.
the motor does go up and down put it does not pull the headrest with it.
i could not find a release.. when pressing the switch the motor goes up or down the the two latches release but nothing. I even tried to to push while someone held the switch down....
help please.....

30+ views and no one able to help 
if im pressing the button up and down and the hear rest motor go up n down this means its not a fuse or relay right?
I tried to manually lower the top but thats a headache on its own...
Again this is a 2002 430 w208 there is no manual release latch as in the w209

In the event of crash deployment tensioned springs supply the force to raise the rollbar and the hydraulic system for the rollbar remains passive.
See post #4 at https://mbworld.org/forums/clk-class...f-problem.html for additional information on rollbar components and operation.

Thanks for the reply and link, I don't think its the hydraulics that are locked because the motor that raises the bar does work up and down but the bar seeps to be locked some how. I guess i will have to pull everything apart to get to the issue.

If you read the rollbar theory of operation, during a crash (or severe bumps) the rollbars raise via springs being triggered and independent of the hydraulic system.
The springs are clearly shown in the diagram, are now extended and need to be compressed/reset.

I appreciate your help, it is impossible to try to push down even with 2 men since there is no clearance with the top on.
im trying to see if i could put the top down so that it would be easy to push while a 3rd person unlocks the switch.

Have you tried pushing down both headrests at the same time?
The reason I mention this is because there is a synchronization shaft, part #30 in the diagram, at the bottom of the assembly, that runs in pinions in a rack on both sides to prevent the rollbar from canting.

Yes, one is pressing the the down switch to get both side latches to unlock and myself and my other friend are pushing down at the same time with all our strength but its not even moving its locked up good.

ok, update, i was able to make the headrest move down about 2-3 inches but using a big wrench with leverage but unable to put more force to keep going. this was while the button was pressed down (releasing lock) im going to have to lookup how to manually lower the top because if i can get the top out of the way then it should be alot easier to lower. if anyone has a link to the page that gives u step by step please post, i will start looking
thanks
thanks

I may have found the problem.
when you press the up and down switch the the motor goes up and down but it does not pull or push the headrest... I unbolted the whole frame and found that the the point where in lock up yo the piece that has like a goldish bronze ball was off so the motor part that goes up and down was not locking.. i found 4 little silver wheel bearing ***** it looks like the locking thing broke off or disconnected. i tried to push it in but it was not working.. I'll take a closer look tomorrow and report back.

ok, got it, when the the car senses a roll it automatically releases the lock and the springs push the bars up. that realize stays open so the little 4 bearing ball don't fall into place in order to lock it again. you must follow the wire behind that motor (i was wandering what that motor was for) unplug it and add 12v to it and hold it. that will cause the motor to engage and open so that the wheel bearing ***** can go in. now use the up and down switch to raise it so that it could go into the housing and then remove the 12v power. this will deactivate the motor and push the bearings out and locking it in place...
ohh and yes this is down when the whole frame out so that you could work in the back..
I will include a tutorial later with pictures cause i know there is no info on this...
yes i know you guys are confused lol

Roll bar issues, HELP
I see this is an old thread but it sounds like the exact thing I need to figure out.
I too can't budge the roll bar even with the lock pawls manually pressed. Long story....
Can anyone explain this method any clearer. PLS
I have an ongoing thread regarding my issue and this sounds like the best fix yet but it's not clear.
Thanks, Jack

One thing I couldn't see here is both Manually Lowering Release Levers, It kinda looks like it's showing one, but doesn't stat what it does and also will do no good to find one as both need to be depressed at the same time for the roll bars to manually lowered. It's Winter time here in Kansas, and I put a new battery in and was resetting the Top and Roll bars when I found myself STUCK in below freezing weather. Top stuck down due to roll bars not going down, thus clearance for top to rise is NOT HAPPEN'N Captain. After weeks of stress and studying and trying to poke at it with a welding stick, I FOUND THIS seeming to be the only video and instructions to manually lower the ROLLBARS on an 208.465. Hope this saves someone else a few gray hairs.

To lower Roll bar on w208 clk
ok to lower the Roll bars in a W208 clk
once you have removed the back seat& Bench
which is quite simple to do
lift the seat and pull forward ,
then fit the Bench x2 13mm Bolts Left and right side with 10mm in the centre
then lower arm rest pull out the card insert and you have x2 small screws to undo
then pull out from bottom and lift at the same time, it will come out with a jiggle , once out remember to undo the speaker/ reverse sensor wire
now to lower the Headrest!!
get x2 pairs of Rachet straps loop the strap under the framework feed it up and over the Headrests , then hook the ends to where the Hydraulic springs are anchored,
now you ideally need a friend , once you have both straps in place with a slight bit of Tension on them
both you and your friend to Hold a Flat head screw driver push them through the Gaps in the framwork you will see a Latch that needs to be pressed back , once you have these pressed back Bith you and friend start to Rachet then you will start to see the Roll bars being lowered
try to hold back the latches as you do this ok
( or even better if you had a screwdriver like Tool
with a 90 degree bend on the ends this would work better but I hope this helps someone out
once Roll bars are in place then you can carry on with the manual process of lowering your roof
