What does SVS on the car dashboard mean?

When the SVS light appears on the car dashboard, it indicates that the ECU (Engine Control Unit) or TCU (Transmission Control Unit) of an electronically fuel-injected vehicle has detected a fault in the engine or automatic transmission. All electronically fuel-injected vehicles are equipped with an SVS warning light. For manual transmission vehicles, it serves as the engine fault indicator, while for automatic transmission vehicles, it indicates faults in both the engine and automatic transmission. If the SVS light illuminates, it is recommended to visit a car dealership or service center for inspection as soon as possible. The SVS light is a warning indicator for abnormalities in the vehicle's emission system. If there are no other unusual symptoms while driving, it is often caused by poor-quality gasoline. The SVS light is a standard indicator in the automotive industry, responsible for alerting users to power system abnormalities and prompting them to take the vehicle to a service center for maintenance.

When I saw the SVS light on the dashboard while driving, I got nervous immediately. After checking the manual, I learned that it stands for 'Service Vehicle Soon,' which means the car system is reminding you to service the vehicle. It could be caused by issues like a faulty engine sensor, oil pressure problems, or a malfunctioning electronic control unit. Once, I ignored the light, and after driving for a few days, the engine almost broke down, costing me a fortune in repairs. Now, whenever the light flashes, I either stop to check or head straight to the repair shop—safety first. Related experience: Regular maintenance, such as changing the oil and air filter every six months, can significantly reduce the chances of this light coming on and also extend the car's lifespan, saving money.

Why is the engine still making noise after turning off?

Here are the reasons why the engine may still make noise after the car is turned off: 1. Cooling sound of the catalytic converter: The normal operating temperature of the catalytic converter is 400-800°C. After turning off the engine, its operation gradually stops, and the temperature drops, causing the internal metal components to expand and contract due to heat, resulting in abnormal noises. 2. Turbo cooling sound: Normally, the exhaust gas temperature reaches 600-700°C, accelerating the friction-generated heat from the rapidly rotating turbo. After turning off the engine, the thermal expansion and contraction are quite noticeable, leading to abnormal noises. 3. Uneven engine cooling: After driving for a while, the engine temperature is very high. When turned off, the temperature of various components drops, and the thermal expansion and contraction cannot occur uniformly, inevitably causing friction between internal metal parts due to cooling contraction, resulting in abnormal noises. 4. Cooling fan operation: The fan will automatically shut off once the water temperature drops, so there's no need to worry. If the cooling fan is still running, it means the engine temperature is still too high, and the fan will continue to operate for one to two minutes.

Due to the confined space, the operation is difficult. 2. The air conditioning filter purifies the air entering the cabin from the outside, improving air cleanliness. It typically filters impurities in the air, including tiny particles, pollen, bacteria, industrial exhaust, and dust. 3.
