What Are the Reasons Why Auto Start-Stop Doesn't Work?

Reasons why auto start-stop doesn't work include: accidentally pressing the auto start-stop button, not starting the vehicle according to the correct steps, differences in auto start-stop system design, vehicle conditions not meeting the start-stop requirements, and system malfunctions. Below is a detailed explanation: Accidentally pressing the auto start-stop button: Vehicles equipped with auto start-stop functionality have the system enabled by default. If it suddenly stops working, it may be because the auto start-stop button was accidentally pressed, turning the system off. Check whether the system has been disabled. Not starting the vehicle according to the correct steps: For manual transmission cars, the conditions for enabling auto start-stop are more complex. The system will only activate when it detects three actions after stopping: shifting to neutral, engaging the handbrake, and releasing the clutch. Differences in auto start-stop system design: Different models from various brands have different designs for their auto start-stop systems. For example, the auto start-stop system in the new Passat requires certain conditions to be met. Specifically, the seatbelt must be fastened, the front left door must be closed, and the engine must be restarted. It’s important to refer to the user manual for specific instructions. Vehicle conditions not meeting auto start-stop requirements: The auto start-stop function will not activate under the following conditions: 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 stopping, the vehicle is in emergency braking mode, or the vehicle is reversing. System malfunction: If the auto start-stop system malfunctions, it may be due to wiring issues or other reasons preventing the system from working. In such cases, it’s necessary to take the vehicle to a 4S shop for inspection and repair.

What Causes Car Shaking During Start-Up?

Reasons for car body shaking after start-up: unstable oil pressure, aging engine components, and severe engine carbon buildup. If the car shakes during start-up, it is recommended to promptly visit a 4S shop for inspection and repair to avoid greater safety hazards. Below are the detailed explanations: Unstable Oil Pressure: Abnormal fuel pump supply pressure or incorrect and poor performance of the intake pressure sensor can cause body shaking. Solution: Check the oil pressure and replace components if necessary. Aging Engine Components: Car shaking is also related to aging engine mounts. Engine mounts are essentially the shock absorption system of the engine, responsible for absorbing minor vibrations during operation. If the engine mounts are faulty, these vibrations will transfer to the steering wheel and the cabin, causing shaking during idle. Solution: Replace engine components. Severe Engine Carbon Buildup: The most common cause of car shaking is a dirty throttle body or excessive carbon buildup in the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold start injector will be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start. Solution: Clean the fuel system and check if the idle control valve has carbon buildup that needs cleaning.

What does 'Please change the engine oil immediately' mean?

"Please change the engine oil immediately" is a reminder to the vehicle owner that the engine oil is running low and needs to be replaced. The method for changing the engine oil is as follows: 1. Lift the vehicle, remove the protective plate, and place a container under the oil drain screw; 2. Unscrew the oil drain screw, use an air gun to blow for two minutes at the oil filler port, then tighten the oil drain screw after draining and wipe it with a tissue to check for leaks; 3. Reinstall the protective plate and lower the vehicle, then add new oil through the oil filler port. Precautions for changing engine oil: 1. Perform the operation while the engine is warm to ensure the old oil is drained as completely as possible; 2. Add the new oil and ensure the amount is appropriate; 3. After adding the oil, start the engine and check all components for leaks. Run the engine for 3 minutes to confirm the oil level is at the normal mark.
