What's the matter with BMW's auto start-stop malfunction?

[GiaLee]

The reasons for Volkswagen Sagitar's auto start-stop malfunction include insufficient battery power and throttle valve failure. Auto start-stop malfunction handling: When the vehicle is temporarily parked or stops at a traffic light, the engine will shut down briefly on its own. When resuming driving, there's no need to operate the ignition switch key as the engine will restart automatically. During vehicle movement, when encountering traffic congestion or a red light, the driver should press the brake until the vehicle stops and keep holding the brake without releasing it. At this point, the engine will automatically shut off and then restart. Auto start-stop system working conditions: The driver's door must be closed, the driver must fasten the seat belt, the engine hood must be closed, and during use, the vehicle must be braked to a complete stop with the brake pedal pressed.
