Eventually it opens the shade all the way but, upon command, it does not open the roof beyond tilt position...

When it is open, both roof and shade or just the shade, the command always work to close them.

But the open command effectiveness vary... most of the times not working to open the shade further than the 15cm or the roof beyond tilt position...

I took to the dealer and, once there, it would not open at all... Later, at home, I managed to luck out an opening... It has been intermitent...

Their diagnostic was to change the Roller Blind (Part# 39824857)... but I am not confident at all... The part alone is US$700+... and, for some reason, I am suspecting that it is not what will solve the problem...

Have anyone experienced something similar? Did/how did you solve it?

That sounds more like a communication issue between whichever module controls the roof, the switch & the motors.
