Driver's window replacement
Almost all cars have the same door construction. The panel is held on by a handful of screws that are mostly hidden. Once removed pull up slightly and it will pop out of track on the top. Then disconnect the wire harnesses. The door handle can differ but there is usually an easily removable cable.
Now you have access to the window track. The window is connected to the track at the bottom. Disconnect at the bottom and pull out.
The challenge at the junkyard is the window is rolled up, there is no battery, and you want the window down. But you can pull the panel there and see how to access the window track bolts. Just a suggestion.
here is one for the Q7. it will not be much different from the Q5
