What causes the automatic start-stop failure in Lavida Plus engine?
4 Answers
Lavida Plus engine automatic start-stop failure is caused by low battery power, excessive temperature difference between inside and outside the vehicle, and low-speed driving. The specific reasons are as follows: Low battery power: When the vehicle does not reach the ideal working state, low battery power and insufficient voltage can cause the automatic start-stop to malfunction. This is because during engine shutdown, the engine cooling fan and in-car air conditioning require power to operate. Engine coolant temperature being too high or too low can also cause the automatic start-stop to malfunction. The solution is to charge the car battery in time to ensure sufficient battery power. Excessive temperature difference between inside and outside the vehicle: When the vehicle does not reach the state set by the driver, such as when the air conditioning is turned on in summer, if the engine is shut down, the air conditioning compressor will not work. Once the temperature inside the car differs too much from the set temperature, the automatic start-stop system will malfunction. The solution is to allow air convection inside the car, gradually bringing the interior temperature closer to the outside temperature. Low-speed driving: During low-speed driving, if the speed does not reach 5km/h after starting, or if there is repeated acceleration and deceleration with speed below 15km/h, the automatic start-stop may malfunction. The solution is to avoid continuous low-speed driving and maintain a steady speed.
I've been driving a Volkswagen Lavida Plus for over a year, and the auto start-stop system frequently malfunctions. At first, I thought it was due to incorrect operation, but later I found out the main reason is battery aging. The auto start-stop requires sufficient power to start the engine. If the battery is over two years old, its capacity decreases, and the system automatically shuts down to protect the battery. Additionally, when temperatures are too high, such as during summer exposure to direct sunlight, the system disables to prevent overheating. I've also noticed that the start-stop often doesn't work when the air conditioning is on because the AC consumes a lot of power and takes priority. It's recommended to first use a multimeter to check the battery voltage; if it's below 12V, it means the battery needs replacement. Don't underestimate this issue—city driving benefits from the fuel and effort savings of the start-stop system, and malfunctions can be quite annoying. It's best to quickly visit a shop to check the battery or update the system.
As a car enthusiast, I've done my homework on the automatic start-stop mechanism of the Lavida Plus. Most malfunctions stem from sensor or circuit component issues. For instance, when speed sensors or brake light sensors fail, the system can't receive correct signals and will deactivate. Circuit failures are also common, such as blown fuses or control module software bugs - the Lavida Plus's onboard computer requires regular updates. Environmental factors like low temperatures may cause sluggish responses, but mainly it's design flaws or aging components. I recommend using an OBD scanner to read fault codes, which can precisely locate the root cause. Avoid tampering with engine-related parts - professional repair is crucial. Proper usage can extend the system's lifespan.
The automatic start-stop function of Lavida Plus is malfunctioning. First, perform a simple check yourself. See if any warning lights are illuminated on the dashboard; if the battery connection is loose or the voltage is low, the system will automatically deactivate for safety. When the air conditioning is set to a high temperature, the start-stop function will also pause to prioritize the air conditioning. Try letting the car run for a few minutes after a cold start—sometimes resetting the system will restore functionality. Battery maintenance is crucial; avoid frequent short trips that can lead to battery drain. These minor daily issues are easy to handle, so don’t let them disrupt your driving.
