This used OEM Audi door wiring harness, part number 8W0971687BP, is the left-rear unit removed from a donor vehicle. Also called a door loom, it carries power and signals for windows, locks, mirrors, and speakers through the rear door. A common failure point is broken wires inside the rubber boot between the door and body, leading to intermittent window or lock operation. This genuine Audi harness is a direct replacement for the original equipment part.
