What is the reason for the exclamation mark appearing when starting a BMW X6?
2 Answers
An exclamation mark appearing on the car dashboard may indicate a parking sensor failure, brake pad wear exceeding the standard, engine oil pressure sensor failure, insufficient brake fluid, fuel cutoff system intervention or failure, etc. Triangle with an exclamation mark in the middle: This is a general fault indicator light, which mainly lights up under the following circumstances: dry dual-clutch transmission clutch overheating, fuel cutoff system intervention or failure, parking sensor failure, external light failure, engine oil pressure sensor failure, traction control system warning or failure. Bracketed circle with an exclamation mark in the middle: This is the brake system warning light, which lights up under the following conditions: the light comes on for a few seconds after turning on the ignition and turns off after starting the engine. It lights up when the handbrake is engaged and turns off when released. It lights up when the brake fluid level is too low or when there is a brake system failure during driving. Horizontal line under brackets with an exclamation mark in the middle: This is the tire pressure monitoring warning light, which lights up when the pressure in one of the vehicle's tires is too low.
Hey, I've been driving a BMW X6 for several years and often encounter the exclamation mark warning light during ignition. It's mostly related to the braking system, like low brake fluid level. The dashboard has min-max indicator lines - if it's below, you need to top up with DOT4 brake fluid. Insufficient tire pressure could also be the cause, especially in winter when cold air makes pressure drop faster, triggering the TPMS sensor alarm. I've experienced cases where the light flashes briefly at startup then disappears, probably due to poor wiring contact or loose sensors. Don't underestimate it - last time I ignored it and later the brake pedal feel became spongy, nearly causing an accident. The best approach is to directly visit a 4S shop or repair shop to scan for diagnostic trouble codes - it's convenient and accurate. For daily maintenance, simple self-checks after turning off the engine: inspect fluid levels and tires, addressing any issues early saves money and gives peace of mind.
