This used OEM starter/alternator wiring harness and battery cable, Audi part number 4M0971228BT, came from a donor vehicle. Also known as the starter harness or alternator wiring harness, it was originally installed on the 4.0L V8 mild-hybrid (MHEV) engine found in the Audi SQ7 and SQ8. Over time, this cable assembly can develop corrosion or damaged insulation, leading to intermittent starting, reduced alternator output, or battery charging faults.
