What does the yellow exclamation mark in Volkswagen cars mean?

[Myers]

There are four possible scenarios when a yellow exclamation mark appears on the car dashboard: general malfunction, automatic transmission failure, abnormal tire pressure, and lighting system failure. Below is a detailed analysis of these four situations: General Malfunction: A triangle with an exclamation mark inside indicates a malfunction in the car's general 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. It is necessary to visit a 4S shop for inspection to identify the source of the problem. Automatic Transmission Failure: A yellow gear with an exclamation mark inside is the automatic transmission warning light, indicating a transmission fault or that the transmission fluid level is below the normal range. The transmission fluid should be replaced promptly. Abnormal Tire Pressure: An exclamation mark inside a horizontal line under a parenthesis represents the tire pressure monitoring warning light. This light turns on when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting System Failure: A yellow bulb with an exclamation mark is the lighting system failure indicator, signaling a malfunction in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or perform a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue. There is also a red exclamation mark inside a circled parenthesis, which represents a warning for the braking system, mainly indicating a braking system malfunction or low brake fluid level. Immediate inspection of the braking system is required to avoid accidents.
