What does the Volkswagen faulty engine auto start-stop system mean?
1 Answers
Engine auto start-stop is a system that automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) during driving. When it's time to move forward again, the system automatically restarts the engine. Its English name is STOP&START, abbreviated as STT. The STT intelligent fuel-saving system is a set of controls for engine start and stop. Reasons for engine auto start-stop failure: Volkswagen vehicles displaying auto start-stop faults are generally due to insufficient battery power, as auto start-stop vehicles have higher power requirements for the battery, or due to throttle valve faults, etc. When a car experiences an auto start-stop malfunction, it is recommended to seek a mechanic to check the cause as soon as possible to avoid other unnecessary losses. Auto start-stop mainly relies on: Battery capacity. When starting the car, the very high current consumes a large amount of battery power, so cars equipped with the auto start-stop function use high-capacity batteries that can withstand large current impacts. When the battery power is consumed to a certain extent and can no longer continuously provide the huge current required, the auto start-stop will automatically deactivate to protect the battery and maintain its usage cycle. If the auto start-stop still cannot be used after the battery is fully recharged, it means the original battery can no longer meet the ultra-high current demand of the auto start-stop, and a new battery must be replaced.
