My rear passenger window has slipped down... i have it taped up just now but need to fix it asap! Is this a common thing? I did search but couldnt find anything...

I have experienced this in an Octavia - the carriage basically slipped and I lost the window in the door completely!!! I ended up taking it to a Skoda garage for a repair - cost me about £120.

There is a plastic peg located in a hole in the bottom of the glass which holds the glass to the regulator, it is likely that this peg has broken. It might be more cost effective to take it to a specialist windscreen company.
