jovie75,

welcome to the forum! What you are writing is very hard to understand. Could you try again to give us a precise description? Try full sentences, less mumbling, and correct spelling. If you put more effort into your post, then the good folks on this forum will be more motivated to help you, and we will probably find a solution faster.

ODBII will not read soft top error codes.
Does your CLK have the feature where windows drop a few millimeters when you open the doors?

Precisely, what do you mean by "if i touch its relay starts to pump"?

jovi75

When i active the switch of the rollbar they move ande the hydraulic pump works.
if with a screwdriver i switch on the relay that is mounted on the pump the motor of the to pump turn on.

jovi75

In the picture you may see the relay.
if i remove the plastic cover of this relay...with i screwdriver con switch it on..and the pump start pumping.

Only one question....
may be that having disconnected the battery of the car...
the soft top need to be re-syncronized ?..with a open/close manually ?.

You only need to re-synchronize the soft top, if it was in a partially open position when the battery is discounted.

In the USA owner's manual, when the battery is disconnected, the systems that need to be re-synchronized are explained on page 265 (e.g. clock, front seats, windows, electric stability program and sometimes the soft top).

Sounds like you have already done some research / reading of prior posted problems.

The soft top controller will check for certain conditions and if present, then initiate the next step

From reading through your prior comments, after unlatching the locking handle, the windows will lower, if necessary the roll bar will lowered by the hydraulic pump etc..

The hydraulic pump (and the relay that starts it) seems to operate OK through the roll bar operation. However, later in the opening sequence, it doesn't.

The soft top opening sequence, conditions of what the controller must see to initiate the next step are detailed in post #16 at:

https://mbworld.org/forums/clk-class...-failures.html

Have you checked that (3) soft top cover locking switches and/or wiring are in proper condition (e.g. the roof operation will not proceed unless the rear soft top cover is open)?

Since you already have access to the pump, have you tried temporarily swapping the fuel pump relay in place of the pump relay?

jovi75

Well....the raleys of the idraulic pump is new.
Well....now i'll try to open it manually ...and i'll check each switch..of the soft top and of the tonneau/cover.
does anybody have the full sequence that the soft top follow?.

The status of every position/limit switch vs. each stage of the soft top opening are in the attachments in the post/link previously sent.

Additionally, within that thread there are many tips and more importantly, specific problems found and how to repair.

jovi75

Before of opening the soft top manually...
1'must i disconnect battery ?
2' could you send me a sequence of opening of the soft top ?.i've seen that in topics there many witch is the best ?.

Thanks

The battery is not disconnected for manual operation of the soft top.

You need to release the hydraulic pressure and unlock the top cover using the tools in the MB toolkit.

You will find the factory instructions, with pictures, in the Practical Hints section of your owners manual.

I 've made the reset procedure after that i've mounted the new relay.
i've disconnected battery 2 hours to reset the cpu.....m.
and now my soft top works great....


Whell i think i 'll leave the back of the car open for half month..to see 9il level for leakege. .....

thanks to everyone for help!!+!!
