After checking every last switch in the Vario roof system, I still cannot get this thing to open properly.

It begins to open, then when the roof section is halfway open (rear window part nearly vertical), it stops. No reaction from there, except killing ignition lets the thing settle into the trunk/boot. The trunk lid remains open. Restoring power and trying the roof switch in either direction makes the hydraulic pump run, but it seems to be trying to push the folded roof assembly deeper into the trunk cavity.

Does anyone have information about the system:
1. A blow-by-blow logic flow diagram of what happens when in the process of opening/closing the roof.
2. A pic/description of where the module is that controls the roof process.

There is obviously some logical condition that comes into play at the mid-point of roof opening. I would like to tap into the signals from all the switches to monitor this process nad see where the fault is. I likely have a wiring fault, as the switches are all OK.

I've dug deeper into the roof system than what I have heard about on these forums, and have done extensive searches here and elsewhere, and I'm stuck. I'm an EE so I'm not afraid of the electronics (I'll make my own damned controller if needed)...

Thanks to all on here - this forum has been a godsend for info about these rather poorly-documented little cars!
