What does the exclamation mark in a car mean?

There are three situations regarding the exclamation mark in a car: 1. An exclamation mark inside a triangle indicates a general fault warning light; 2. An exclamation mark inside a circle with brackets is the brake system warning light, which illuminates when the parking brake handle is pulled up and turns off automatically when the handbrake is released; 3. An exclamation mark with a horizontal line below brackets is the tire pressure monitoring warning light, which lights up when the tire pressure is insufficient. The car dashboard is a device that reflects the working conditions of various vehicle systems. Common indicators include the fuel indicator, washer fluid indicator, electronic throttle indicator, front and rear fog light indicators, and warning lights. Standard gauges include the speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, and charging gauge.

What Causes the Zizzing Sound When Driving?

The reason for the zizzing sound when driving is: the brake pads have worn to their limit, causing the brake drum to come into direct contact with the vehicle. Under normal driving conditions, the front brake pads need to be replaced every 30,000 to 50,000 kilometers, while the rear brake pads can last for about 60,000 to 100,000 kilometers before needing replacement. The wear level varies depending on the driving conditions of each car. You can determine whether replacement is needed by checking the thickness of the brake pads. Typically, new brake pads are about 1.5 centimeters thick. There is a protrusion on both ends of the brake pad, approximately 3 millimeters in height. If the thickness of the brake pad is level with this indicator, it should be replaced immediately.

What is the fault when the Audi EPC light is on?

The EPC indicator light has two states of illumination: self-check upon power-on and illumination under other circumstances. The self-check upon power-on is an indication that the vehicle monitors the status of all sensors before driving. Generally, if the vehicle is not started after power-on, the light will turn off by itself after about 3 seconds. In other cases, if the EPC light remains on or does not turn off for a long time after the vehicle is started, the main reasons for the EPC light staying on include faults in the engine intake system, throttle body, fuel system, engine, ECU control unit, or brake lights. Below is a detailed introduction to the causes of the EPC light being on under other circumstances: Engine intake system fault: The EPC light will illuminate if the engine intake is obstructed or insufficient. Throttle body fault: Carbon buildup is a common issue with the throttle body. Additionally, dirt accumulation can affect intake, causing the light to illuminate. Fuel system fault: For example, substandard fuel, deteriorated fuel, or poor fuel atomization. Engine fault: Insufficient engine pressure or issues with the intake valves and other power system components can also trigger the EPC light. ECU control unit fault: Such as interference with the vehicle computer signals or false alarms from the vehicle computer. Brake light fault: If the brake lights do not illuminate, the brake switch malfunctions, or there are issues with the brake wiring. Solutions for when the EPC light illuminates: Troubleshoot the intake system, use fuel with the appropriate octane rating, clean the throttle body, etc. Remove carbon buildup from relevant parts. Re-flash the ECU data. If the EPC light illuminates, the owner can first try turning off the engine and restarting it to see if the EPC light remains on. If it does not illuminate again, there may be no issue, possibly just interference affecting the EPC light. If the EPC light remains on or frequently illuminates, the vehicle should be taken to the nearest service point for professional diagnosis and repair to promptly eliminate safety hazards. When the engine operates unstably, check the following: Inspect the spark plugs and cylinder wires. Test the fuel pressure system. Check the fuel injectors for each cylinder. Inspect the fuel pump and its circuit. Check cylinder pressure, intake and exhaust valve clearance, fuel vapor control solenoid valve, EGR valve operation, and intake manifold leaks, etc. There are many reasons for unstable engine operation. Therefore, after an issue arises, it is essential to visit a service center for systematic checks to accurately identify the fault and determine the solution. The full English name of EPC is Electronic-Power-Control, which translates to electronic power control. Most people refer to it as the engine electronic stability system. The EPC system mainly includes controllers and sensors related to the powertrain. When sensor data in the system is abnormal, the EPC system will take predefined measures for the powertrain. Common EPC indicator lights generally display two colors: yellow and red. If the EPC fault light is yellow and the vehicle can still operate normally, proceed slowly to a service point for inspection. If the EPC fault light is red, the situation is more severe, and the vehicle should be pulled over immediately to contact a professional for repair. Continuing to drive may directly affect the vehicle's core components or driving safety.
