What does the exclamation mark on the Audi A3 mean?

[LeHannah]

The appearance of an exclamation mark on the car's dashboard indicates an abnormality or malfunction in the corresponding system. There are many indicator lights on the car dashboard that feature an exclamation mark, such as the tire pressure indicator, lighting fault indicator, steering system fault indicator, brake system fault light, transmission fault indicator, and wiper fault indicator. Below is a detailed introduction to the exclamation mark warning lights: General Fault: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a fault in the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating a transmission malfunction or transmission fluid level below the normal range. The transmission fluid should be replaced promptly. Brake System Fault: A circle with parentheses and an exclamation mark in the middle. This represents a brake system warning, mainly indicating a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire Pressure Abnormality: A horizontal line with parentheses and an exclamation mark below. This represents the tire pressure monitoring warning light, which illuminates when the car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator, indicating a fault in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or check yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights, to identify the problem. In addition, during daily use of the vehicle, the fault lights displayed on the dashboard are divided into two different colors, yellow and red: Yellow indicates a fault in the corresponding system, but the problem is not very serious. Reduce speed and proceed to the nearest repair point to eliminate potential safety hazards. Red indicates a very serious problem in the corresponding system. In this case, do not continue driving. Pull over immediately and seek professional assistance to prevent unpredictable dangers to the vehicle and personal safety. It should be noted that when the car is started, all lights will illuminate for a system self-check and will automatically turn off after the check is completed. If a light does not illuminate when the ignition is turned on, remains lit, or lights up while driving, it indicates a fault in the related system. In such cases, seek professional help promptly for inspection and elimination of potential safety hazards.
