This Audi Electric Seat Belt Adjusting Motor (OEM 4E0857833A) is a genuine used OE part removed from a donor vehicle. It also replaces 4E0857833 and controls the powered fore/aft movement of the seat belt anchor. When this motor fails, the belt height adjuster stops responding or makes grinding noises. As a safety-system component, installation should be performed by a qualified shop or dealer to ensure proper function.
