A work friend had a problem with the plastic bits for holding the drivers side window in a Golf. They broke which resulted in the glass falling down, when trying to lift it, it must have fallen again and smashed. It was the guy replacing the window that pointed out the reason it fell.

Only after searching the net has it showed up that this seems to have happened a lot in the states and that they have been replaced by metal parts instead.

Anyone know if the mechanism in the Octavia is the same ? I showed him photos of my window mechanism the time I had it apart and he thinks it looks different.

yes, I've had the same thing happen to both the rear and front windows in my Octavia. this has plastic sliders. The back one is fiddly to replace ( you have to buy a whole channel at
