Question CLK500 Convertible Top Issue [SOLVED]

Good Afternoon Everybody!

So as of this morning, my soft top is stuck closed. When I pull the button to open the top,
I get a notice on the display saying: TOP - Visit Workshop. But that is all. No window movement
either.

I have checked fuse #28, as well as the large 40A fuse in the boot, both of
which are fine. I have checked the hydraulic fluid level, which is also fine.

The relays next to the pump are not clicking at all when the switch is engaged. I swapped
these two out, but still, they are not engaging. I had my local garage run a quick scan, and
the only current fault stored is: B1075 - No CAN message from control unit OCP.

Could the main switch (the one used to open/close the roof) be faulty?

I'm a bit stumped, and hoping that someone can shed some light on the situation!

Thanks in advance, and thanks to all the contributors to this awesome forum!

Greetings from Cape Town!

Fixed it!

This was the key:
"B1075 - STORED & CURRENT - No CAN message from control unit OCP"

That refers to the Overhead Control Panel - I checked the fuse, looked fine, but after
measuring with a meter, there was no continuation.

New fuse, and all sorted! It's fuse number 9 in the trunk/boot.

Thanks Degeja.
