- 48V Belt Starter-Generator Warning and VIN-Specific Campaigns2019-2025
A 48V electrical-system warning on a mild-hybrid A6 is not repaired with an ordinary 12V battery, charger, alternator, or starter. Certain 2019-2020 2.0T mild-hybrid vehicles are covered by safety recall 27H2 or 20V-153 for moisture intrusion into the belt starter generator, which can cause a short circuit, smoldering, or fire. Audi also issued VIN-specific service action 27BQ for qualifying later vehicles. Outside those campaigns, the exact Audi fault code and symptom number matter: U046900 with symptom 34763 and actual mode 8 can point to another CAN or sensor fault, and Audi states that replacing the starter generator will not fix that case.
