This used genuine OEM Audi part number 4M8839462 is a rear right window regulator, removed from a donor vehicle. Also known simply as a window regulator or power window regulator, this unit is responsible for raising and lowering the rear passenger glass. A failing regulator often causes the window to move slowly, make grinding noises, or become stuck in the closed or open position. It was originally fitted to 3.0L, 4.0L, and battery-electric Q8 models.
