Used Audi alternator wiring harness/cable OEM 8S0971230AD (also supersedes 8S0971230P). This genuine harness connects the alternator to the electrical system, carrying charging current to the battery and ECU. When this cable fails, symptoms include intermittent charging, battery warning lights, or no-start conditions. It was removed from an Audi TT, TTS Quattro, or TT Quattro with the 1.8L or 2.0L TFSI engine. A failed alternator cable often shows melted insulation or broken terminals at the alternator stud.
