This used genuine OEM Door Wiring Harness (part 4H0971029MQ) came from a donor Audi A8 or S8. It’s the front left harness, also superseding 4H0971029MJ, 4H0971029ML, 4H0971029MN, and several other 4H0-series numbers. It routes power and signals to door modules for windows, locks, mirrors, and speakers. A failing harness often causes intermittent window or lock operation. Designed for Audi A8 Quattro and S8 with the listed V6, V8, or W12 engines.
