20221231ELECTRICAL SYSTEM

When started up on 11/17/22, multiple warning lights came on in rapid sequence advising of an electrical system & battery malfunction. Warning was to not drive the vehicle and contact service. I shut off the vehicle and re-started it. The same warnings were displayed. I was about 0.8 mile from the dealer so I attempted to drive it to their location. On the way, the warnings continued to show. After about 0.6 miles, the transmission fully disengaged from the engine. I coasted to the side of the street, shut off the vehicle, re-started it (same warnings showed) but the transmission was reset and worked. I drove to the dealership where my Audi mechanic knew exactly what the issue is--there is a huge problem with a Continental-supplied 48V belt starter/generator that needs to be replaced. However, none are available and won't be available until sometime in Q1 2023 or later. The replacement part is backordered with every Audi dealership experiencing this issue with multiple models in the MY
