BMW Brake Fluid Level Sensor, OEM part number 6873451. This is a used genuine BMW sensor removed from a donor vehicle. Also known as a brake fluid level switch, this sensor monitors the fluid level in the brake reservoir. When the fluid drops too low, it triggers a warning light on your dashboard, alerting you to a potential safety issue or worn brake pads. This part is a direct OEM replacement for the original sensor in your vehicle. It is not a safety-critical component, so no specialized technician installation is required.
