What is the reason why the rear glass of the Passat cannot be fully lowered?

[McReid]

Here are the reasons why the rear window of the Passat cannot be fully lowered: 1. The rear window of the Passat cannot be fully lowered, leaving about one-third of the glass exposed above. This is due to design and safety considerations. The area below the rear door is often near the wheel, and the lower door frame is inclined or curved, resulting in an irregular shape. This reduces the available space below the rear door compared to the front door, preventing the window from being fully lowered. 2. For some models, the wheel arch design causes a noticeable narrowing in the lower part of the rear door panel. When the rear window is lowered, the lower part of the door panel does not have enough space to accommodate the glass, resulting in the window not being able to fully lower.
