[OAlivia]

The reasons for the failure of the Volkswagen Lavida's auto start-stop function are as follows: 1. Accidental pressing of the auto start-stop button: The system may be turned off due to accidental pressing of the auto start-stop button, so it is necessary to check whether the system is turned off. In manual transmission cars, the auto start-stop system will only activate when the system recognizes that the gear is in neutral, the handbrake is engaged, and the clutch is released. 2. Insufficient battery power: The engine auto start-stop system failure may be caused by insufficient battery power, as the battery capacity decreases after long-term use, preventing the car's engine start-stop system from functioning properly. 3. Failure to activate: The auto start-stop function may not activate if the engine has not reached normal operating temperature, the automatic air conditioning has not reached the preset temperature, the battery charge is insufficient, the steering wheel is turned after parking, the vehicle is in emergency braking, or reversing, etc.
