When i open the roof ( by using the  roof button) the roof starts opening but stops at the beginning

Then  I have to open the roof by hand (using the tool at the front and open the hooks. and pulling the roof backwards) the last phase can be done using the roof button on the console. I saw that the lid is not closing well (the hook at lid engine doesn’t grip the lid) and I tried to wiggle a bit at the lid-engine and then the lid closed and locked the lid. So, the roof is completely open, and everything looks ok.

I see that the hooks at front of the roof are in the closed position. Is this normal? If the roof is completely open there is no error.

Closing the roof
Using the roof button for the closing procedure, start is promising. The lid opens and the roof start closing until it is upright then the closing procedure stops.
When I use the roof button again to close the roof, the roof start closing again. Until the roof is almost closed. Then it stops and I get the error that the roof can’t be operated.
The hooks at the front of the roof are still in the closed position (the wrong position).
Due to the error that the roof can''t be operated noting happens. The button doesn’t work anymore
So, I have to shutdown the engine. Release pressure at the hydraulic system by pushing the roof button down for 20 seconds.
Then I can close the roof by hand at the front by using the tool for opening the hooks first 
Then lifting the rear window and pushing the lid forward.
Next step is closing the front of teh roof with the tool by closing the hooks
Last step is( from the inside of teh car) closing the roof at the rear by pushing and pulling by hand at the frame inside the roof. Mind you doing so the lid is not closed hydraulic. I believe this (not closing the lid hydraulic is the reason for water leaking in my trunk.
Now I wil replace the engine at the lid as it seems to be not working correctly /fully operational.
So, I must look were to buy the lid engine.
At this moment I still have a few questions.
Why does the roof stops closing?
Why are the hooks after fully opening in the wrong position (closed?)
What is the reason I get the error the roof can be operated?

it seem sto be microswitch F294. But i cant buy them everywhere? any suggestions?. I thought it was and standard microswitch.

Hello Bjorn,

When you say you cannot buy one anywhere, where have you tried? New or secondhand? 
Kind regards,

Gareth.
