Audi A5/S5 Front Left Door Wire / Wiring Harness OEM 8W7971029CS — a used genuine part removed from a compatible donor. This harness also replaces a series of earlier numbers including 8W7971029BC, 8W7971029BE, 8W7971029BQ, 8W7971029BS, 8W7971029CJ, 8W7971029CL, and 8W7971029CQ. It feeds power and signals to door controls like windows, locks, mirrors, and speakers across 2.0L turbo and 3.0L supercharged/turbo engines. A typical failure is broken wires inside the rubber boot between door and body, causing intermittent window or lock operation.
