Convertible soft top issues CLK320 2001
HI.
This is my first post as I recently took ownership of my aunt's low miles CLK320.
I started to have issues with the roof.
It will not go down. As soon as I unlatch it, the windows go down but the roof does not move. The roof switch is also lit red, solid. It blinks when I try to operate it.
The fuses are fine. The pump fluid level is fine. The rear headrests operate well.
I have also tried unplugging and replugging the battery after waiting 20 minutes in an effort to clear the memory of faults. Did not work.
Not too sure what my next steps should be.
Guidance would be greatly appreciated.
Thx

MontrealW208......Welcome to the forum, where you'll find a treasure chest of help and information, on the maintenance and repair, that will keep the W208/A208 running strong.
The power roof's controller has built in diagnostics, upon which the integrated amp in the main switch, indicates the status (i.e. functionality) of the soft top.
Specifically, the status is analyzed each time you start the vehicle (or turn the ignition switch to position 2), the lamp will turn on briefly and then turn off.
Thereafter, the lamp should only be continuously illuminated, when the switch is pressed, only during the time frame that the top is being operated and until it's properly locked.
However, continuous illumination, when the switch is not pressed, indicates the following fault possibilities:
- A defect in the soft top controller or 1 of it's 3 fused circuits.
-That the soft top or the soft top compartment cover is not properly locked.
-A defective or wiring discontinuity with the main soft top switch.
If the lamp flashes while the switch is being pressed, indicates the following fault possibilities:
-Slow flashing, of once per second, signals either that the top has not been properly locked or if attempting to open the power roof, when the front bow locking handle has not been released manually.
-Fast flashing, of three times per second, signals that the controller thinks that either the trunk is not closed and locked or the luggage partition is not properly closed.
Additionally, the lamp will also flash, once per second, when the switch is not pressed, if the soft top is not properly locked.

Could be a limit switch problem. The procedure to re-synchronize the power roof's position/limit switches is done by opening and closing the roof manually.
When you open/close the roof manually, all the position/limit switches are reset in the proper order. Your manual should have a section on closing your roof manually.

The position/limit switch actuations that are required for a particular stage of roof operation to occur and proceed, can be determined with just a multi-meter (set to measure ohms) at the controller connector (which also verifies that there is not a wiring issue and that their actuation's are in sequence with the controller's programing) .
You'll find the documentation and details in the last couple of pages at https://mbworld.org/forums/clk-class...ilures-10.html

Top opens correctly but does not close
Hi Guys ,
My top goes down as it is supposed to do but it does not come up and close. It simply does nothing when the S84 button is pressed. Button does not either light or flash when pressed.
I have manually closed the top as per owner’s manual, hoping that system will reset but it does not. It will open and fold, following correctly all sequences (as described in the 77.30 Complete soft top; opening, function description found in other posts) but it simply “dies” once the opening sequence is completed.
Checked for leaks and hydraulic fluid seems to be at the correct level at the pump's container.
I don’t know if there are any switches/sensors or other electrical/electronic components within the system that are not involved in the opening sequence but are used in the closing sequence that may be faulty.
Any ideas or recommendations are very much appreciated!
Thanks!!

To close the loop on this;
After manually lowering and putting the top back up + leaving the car battery unplugged overnight, I replugged the battery and the top works just fine...
Thanks for the help.
Glad to be part of the forum.
Cheers.

Voltage to the controller is supplied by 3 fuses (e.g. 2 are located in the trunk's F4 box and 1 in the engine bay F1 box).
Begin by checking, with a multi-meter or power test light, that there is voltage present on both sides of each fuse.

Serndipity thanks for the quick reply.
I tested the 3 fuses for the soft top. Two in the trunk and one in the engine. All 3 fuses were ok and all have voltage on both sides. Used a 12v circuit tester.
Is there a test that you can think for the S84 switch? Or this previous test confirms the S84 is faulty?
Thanks
