What does the yellow triangle with an exclamation mark in a car mean?

A triangle with an exclamation mark inside indicates a malfunction in the vehicle's routine performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor failure. Solution: It is necessary to visit a 4S shop for inspection to identify the source of the fault. The exclamation mark is a common fault indicator in cars. Besides the triangle with an exclamation mark, there are four other forms of exclamation mark indicators: a yellow gear with an exclamation mark inside, a red circle with parentheses and an exclamation mark in the middle, a yellow horizontal line with parentheses and an exclamation mark in the middle, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four situations: Automatic transmission fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a fault in the transmission or transmission lubricant below the normal range. The transmission oil should be replaced promptly. Brake system fault: A circle with parentheses and an exclamation mark in the middle 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 in the middle represents the tire pressure monitoring warning light, which illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in the vehicle's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.

What is the function of the car OBD interface?

The functions of the car OBD interface are: 1. It can view car data in real time; 2. Read fault codes, providing convenience for car repairs, developing car-related functions, and modifying car equipment. The car OBD, also called the On-Board Diagnostics system, can detect the working status of the engine's electronic control system and other functional modules of the vehicle during operation. Car OBD fault codes: 1. The first letter indicates the system that set the fault code; 2. The second character is 0, 1, 2, or 3, with the following meanings: 0 indicates a generic fault code defined by the Society of Automotive Engineers, 2 indicates an extended fault code defined by the car manufacturer, 2 or 3 indicates it varies with the system character; 3. The third character indicates the system with the fault: 1 indicates a fuel or air metering fault, 2 indicates a fuel or air metering fault, 3 indicates an ignition fault or engine misfire, 4 indicates an auxiliary emission control system fault, 5 indicates a car or idle control system fault, 6 indicates a computer or output circuit fault, 7 indicates a transmission control system, 8 indicates a transmission control system; 4. The last two characters indicate the conditions that triggered the fault code.

Why is my Audi A4 having trouble starting?

Audi A4 having difficulty starting is due to issues with the electrical circuit and ignition system. Gasoline engines rely on an ignition system, which primarily consists of spark plugs and ignition coils. Spark plugs are wearable parts that require regular replacement. If spark plugs are not replaced for an extended period, the electrode gap will widen, affecting normal ignition. Additionally, prolonged use can lead to carbon buildup on the electrodes, further impairing spark plug performance. The Audi A4, introduced by FAW-Volkswagen, was among the first models to adopt the long-wheelbase and turbo concepts. Available variants include: 1.8T manual base model, automatic base model, comfort model, and technology-leading model; 2.4L comfort model, comfort sports model, and comfort premium model; and 3.0L quattro all-wheel-drive version.

What brand is Kumho tires?

Kumho is the Kumho brand tire. Features of Kumho tires: 1. Directly analyze various tire tread patterns' water film phenomena and drainage performance through a computer system; 2. The Protector is exposed to the outside, preventing air leakage caused by rim damage and effectively protecting high-value rims. Functions of tires: 1. Tires serve as the medium for transmitting forces between the vehicle and the road surface, transferring driving force, braking force, and steering force to achieve the vehicle's driving, braking, and steering operations; 2. Support the vehicle load, where the vehicle's load causes the tire to sink until the average pressure on the tire's contact area balances with the internal inflation pressure; 3. Reduce and absorb vibrations and impacts during driving, avoiding early damage to vehicle components due to severe vibrations; 4. Adapt to high-speed driving conditions and reduce driving noise, ensuring safety, comfort, handling stability, and fuel economy.

How to Check Tire Wear?

Check tire wear by observing the thickness from the top to the bottom of the tread grooves. The greater the thickness, the lower the wear. There are generally three types of tire wear: 1. Wear on the outer tread patterns; 2. Wear on the middle tread patterns; 3. Wear on the inner tread patterns. Wear on the outer tread patterns is usually caused by issues with the vehicle's wheel alignment. Excessive camber angle can lead to this problem, which can only be adjusted on independent suspensions. If adjustment is not possible, it indicates a problem with the vehicle's chassis, requiring professional repair at a maintenance shop. Wear on the middle tread patterns is typically caused by excessive tire pressure. In this case, check the tire pressure and release some air if it is too high, adjusting it to the standard level. The standard tire pressure is usually indicated near the driver's seat. Wear on the inner tread patterns is similar to wear on the outer tread patterns and is usually due to improper wheel balance, necessitating inspection and repair at a professional maintenance shop.
