Moonroof / panoroof experts anyone? Weird behavior

[grounch]

Hello
First of all, happy new year to everyone, best wishes and successful repairs!
So about repairs...
If there is a feature i love(d) on my X, it's the properly functional (without the small window tilt) panorama roof. Such a pleasure to wind up the hair in summer.
That was until one day it suddenly stopped working properly..


The visor goes back completely, but when comes glass turn to slide back, it lowers, slide about a millimeter, and closes back
Tilt opening works fine.

What i tried in vain:
- Do the usual reset procedure by keeping the roof button pressed. Already did it before for a full relearn cycle. This time it stopped at the glass sliding step. Now that the reset failed, i get sunroof normalization codes A092 A0A2 and the visor closes inch by inch (not all the way when pressing the button forward)
- Remove the battery for a day to give it a charge (unrelated) so all systems have reseted
- Partially dismount the "ceiling" to check if nothing blocks the rails. Nothing blocks the rails...
- Pushing the glass to help it slide back (gently, don't want to worsen the thing..)
- Using ISTA+ ECU calls to trigger the roof operations. Visor responds well, glass does the same problem.


What i will try next:





If someone have an idea it would be appreciated, i really miss this feature.

Is there any sensor in the system that could be faulty?
