A used OEM Audi right convertible door wiring harness, part number 8H1971029Q, from a donor vehicle. This is the original wiring loom for the passenger-side door on B6/B7 Audi A4 and S4 convertibles, handling power windows, locks, and mirror signals. Also supersedes 8H1971029M, 8H1971029N, and 8H1971029P. Over time, repeated door flexing can break wires inside the rubber boot, causing intermittent window or lock failure. Replacing the harness restores reliable operation.
