What does the exclamation mark mean in a Passat?

There are five situations when an exclamation mark appears on the car dashboard, namely general faults, automatic transmission faults, braking system faults, abnormal tire pressure, and lighting faults. The following is a detailed analysis of the five situations: General faults: An exclamation mark inside a triangle. If this symbol lights up, it indicates a fault in the car's general performance or components and functions. Main faults include parking sensor failure, fuel cut-off system intervention or failure, external light failure, engine oil pressure sensor failure, etc. It is necessary to go to a 4S shop for inspection to identify the source of the fault. Automatic transmission faults: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating that there is a fault in the transmission or the transmission lubricating oil is below the normal range. The transmission oil needs to be replaced in time. Braking system faults: An exclamation mark in the middle of a circle with brackets. This represents a warning of the braking system, mainly including braking system failure and low brake fluid level. The braking system needs to be inspected immediately to avoid accidents. Abnormal tire pressure: An exclamation mark in the middle of a horizontal line under brackets. This represents the tire pressure monitoring warning light. When the tire pressure of the car is too low, this warning light will light up. It is necessary to check the tire pressure of the car and restore the tire pressure to the normal range. Lighting faults: A yellow bulb with an exclamation mark. This is the lighting fault indicator light, indicating that there is a fault in the car lights. Solution: Go to a 4S shop for inspection and treatment as soon as possible, or you can check it yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting, to see where the problem is.
The exclamation mark warning light on the Passat's dashboard suddenly lit up, indicating that a critical system in the car has malfunctioned, most likely related to safety issues. The most common cause is a brake system alert, such as low brake fluid levels or severely worn brake pads. If not addressed, the brakes may fail, especially posing significant risks on highways. Insufficient tire pressure can also trigger this light, as underinflated tires are prone to overheating, bursting, or excessive wear. Other possible causes include abnormal oil pressure or charging system failures. I recommend pulling over immediately when the light comes on and not continuing to drive. It's best to keep the owner's manual in the car for reference, as details may vary slightly between different Passat models. Regular maintenance, such as changing brake fluid and monitoring tire pressure, can effectively prevent these minor issues from suddenly affecting driving experience and safety. Safety should always come first—don't risk major consequences for minor neglect.
