Passenger Window Half opens after closure

[obelix54]

On a few occasions when closing the roof or just shutting all 4 windows, the passenger main window will come back down about 1/3 once all 4 have gone up. Has anyone had this and know what causes it ?

Anti trap. To prevent it catching someone’s fingers. Sometimes due to a bit of muck in the runner or simply a hot day making things expand a bit, when the motor senses resistance it backs off.

So long as there isn't an actual obstruction, if it is the Anti-Trap, I happened to be reading this from the manual earlier today:

1. Pull the switch past the resistance point and hold it there. The anti-trap mechanism is restricted and the window opens slightly when the closing force exceeds a certain value.

2. Pull the switch past the resistance point again within approximately four seconds and hold it there. The window closes without the anti-trap mechanism.
