I can't believe how much they complicated this convertible system with computers, hydraulics and sensors just so the user wouldn't have to manually latch the roof when raised, not worth all the potential headaches, in my opinion anyways.
I've had American convertibles and never had any problems whatsoever, even with the older ones.

Did you do a hard reset when the roof was open and the latch parked?
So now with the roof fully retracted and the latch now locked
- valve closed
- reconnected neg terminal
- Started car
- lowered front windows until clicked
- pushed button-roof up, nothing happening, no response, no pump, nothing
- pushed button-roof down, pump runs and latch opens, roof doesn't rise, then get message "latch not closed" even though roof is down
So either way roof stays down and doesn't rise and system is still confused and dumb as heck!
- so I opened the valve to release pressure then raised top manually
- then closed the valve
- pushed button-roof up to try to bring it to the latch and raise the windows, still nothing and back windows now don't rise
so with top still manually raised,
- Pushed button-roof down, after waiting long enough top lowers towards latch, and I think I latched it manually with the hex key, don't quite recall
So I turned off ignition, this time I firstly disconnected neg terminal
- opened valve
- unlatched
- manually retracted top again, oddly I didn't have to unlock the rams again
- closed valve
- closed latch
Though somewhat confused at this point, I'm now waiting and desperately hoping it might work this time after having firstly disconnected the neg terminal, may be that's what the issue is?
Thank you

but if I raise the roof manually and then push button-roof down and insist/wait long enough the roof goes towards the latch, so when pushing button-roof down and i do it long enough it will do the opposite of roof down and actually push towards the latch

Ok I am done for the night. My brain is full!!
This system is controlled by 2 computers, 5 switches, 2 control valves, 2 relays and one pump that is bidirectional and ALL must be in sequence to make it work. This system is easily confused by pushing the open/close button over and over again and by opening the roof when it thinks it is closed and that is the reason for the hard reset when it is open and the latch is parked.
I will think about this in the morning!
