What does the yellow triangle exclamation mark on the Passat mean?

[SanIvan]

If a yellow triangle exclamation mark appears on the dashboard, it may indicate a fault in the braking system. When this light comes on, first check if the handbrake is fully released; if the light remains on after releasing the handbrake, you need to check whether the brake fluid level is normal or if the brake pads are too thin. Here is more information about the dashboard exclamation mark: 1. A triangle with an exclamation mark in the middle: This is a general fault indicator light. It may illuminate under the following conditions: overheating of the dry dual-clutch transmission clutch; fuel cutoff system intervention or failure; parking sensor fault; external light fault; engine oil pressure sensor fault; traction control system warning or fault. 2. A circle with parentheses and an exclamation mark in the middle: This is the brake system warning light. It may illuminate under the following conditions: some vehicles may light up for a few seconds after turning on the ignition and turn off after starting the engine; it lights up when the handbrake is pulled up and turns off when released; low brake fluid level, lighting up during driving; brake system failure.
