What does the white triangle exclamation mark on the Audi A6 dashboard indicate?

[LaLane]

A triangle with an exclamation mark inside indicates a malfunction in the vehicle's general performance, components, or functions. Possible causes include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. Solution: Visit an authorized 4S dealership for inspection to identify the source of the fault. The exclamation mark is a common fault indicator in vehicles. Besides the triangle with an exclamation mark, there are four other forms of exclamation mark warnings: a yellow gear with an exclamation mark, a red circle with parentheses and an exclamation mark in the middle, a yellow horizontal line with parentheses and an exclamation mark, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four scenarios: Automatic transmission fault: A yellow gear with an exclamation mark indicates an automatic transmission fault warning light, signaling a transmission malfunction or low transmission fluid level. Transmission fluid should be replaced promptly. Brake system fault: A circle with parentheses and an exclamation mark in the middle represents a brake system warning, typically indicating brake system failure or low brake fluid level. Immediate inspection of the brake system is required to prevent accidents. Tire pressure anomaly: A horizontal line with parentheses and an exclamation mark in the middle indicates a 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 a lighting fault indicator, signaling a malfunction in one of the vehicle's lights. Solution: Visit a 4S dealership for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.
