What's the reason for an Audi vehicle having no power at all?

Complete vehicle power loss refers to a no-power malfunction in a car. When encountering such an issue, it should be promptly inspected and repaired at a service center. The possible causes for a complete vehicle power loss include: 1. Battery aging or complete failure. 2. Prolonged parking: The battery may be depleted due to the vehicle being parked for too long. 3. Electrical circuit malfunction: Issues in the car's electrical system preventing battery power from reaching the entire vehicle. 4. Fuse damage: Burned-out or poor contact in the vehicle's fuse circuit, etc. Additional information: The jump-start method can be used: First start the donor vehicle, then connect the batteries correctly with jumper cables, ensuring proper polarity (positive to positive, negative to negative). Once connected, attempt to start the engine. Normally, the vehicle should start on the first try. If there's no response, promptly check whether the vehicle's wiring is functioning properly.
A few days ago, my car had a similar issue where the dashboard went completely black and even the headlights wouldn’t turn on. After checking, I found the battery was completely dead—it measured only 8V with a multimeter. If the car sits unused for too long, the battery may automatically go into anti-theft sleep mode. After jump-starting, it’s best to drive for about an hour to recharge. Loose or corroded battery terminals can also cause poor contact—just sand them down with sandpaper. Another possibility is a blown main fuse, especially the big 80A one in the engine compartment fuse box. Once, mine blew after water got in during a car wash—you’ll need to open it and check the fuse’s color. If all else fails, call roadside assistance—tinkering yourself could damage the circuit board.
