What does the triangle exclamation mark in BMW 3 Series mean?
1 Answers
A triangle with an exclamation mark indicates a malfunction in the vehicle's general performance, components, or functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. Solution: Visit a 4S dealership for inspection to identify the source of the fault. The exclamation mark is a common fault warning in vehicles. Besides the triangle exclamation mark, there are four other forms of exclamation mark warnings: a yellow gear with an exclamation mark, a red circle with an exclamation mark inside parentheses, a yellow horizontal line with an exclamation mark below parentheses, 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 issue or low transmission fluid. The transmission fluid should be replaced promptly. Brake System Fault: A red circle with an exclamation mark inside parentheses represents a brake system warning, typically indicating a brake system malfunction or low brake fluid. Immediate inspection is required to prevent accidents. Tire Pressure Abnormal: A yellow horizontal line with an exclamation mark below parentheses indicates a tire pressure monitoring warning light, which illuminates when tire pressure is too low. Check and adjust tire pressure to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is a lighting fault indicator, signaling a malfunction in the vehicle's lights. Solution: Visit a 4S dealership for inspection or check commonly used bulbs such as turn signals, fog lights, or interior lights to identify the issue.
