This used OEM Audi electric seat belt motor / pretensioner, part 8W7857759, is the left-side unit from a donor Audi A5 or S5 with 2.0L turbo or 3.0L supercharged/turbo engines. In a crash, the pretensioner instantly tightens the seat belt to reduce occupant movement. A failing pretensioner may cause the belt to remain loose or trigger a warning light.
