What does the white triangle exclamation mark in a BMW 3 Series indicate?
1 Answers
A triangle with an exclamation mark inside indicates a malfunction in the vehicle's general performance, components, or functions. Common causes include parking sensor failure, fuel cut-off 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 warning 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 inside, a red circle with parentheses and an exclamation mark in the middle, a yellow parenthesis with a horizontal line 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 transmission malfunction or transmission lubricant level 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. Immediate inspection and repair of the brake system are required to avoid accidents. Tire pressure abnormality: A parenthesis with a horizontal line and an exclamation mark in the middle represents the tire pressure monitoring warning light. This light 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 one of the vehicle's lights. Solution: Visit a 4S shop for inspection as soon as possible. Alternatively, you can perform a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting, to identify the issue.
