51321938884 is the BMW part number for a Window Regulator Sliding Piece
(also known as a guide rail slider or pivot clip).
This small plastic component is a common failure point in BMW window systems, as it secures the window glass to the regulator and allows it to move smoothly along the guide rail.
Product Details Function: It serves as the primary connection point between the regulator arm and the window glass.
Common Issues: These clips often become brittle over time and snap, causing the window to tilt, move slowly, or stop working entirely.

Quantity Needed: Most front windows use two clips per door. It is generally recommended to replace all clips on a door at once while the panel is removed.
