The BMW brake fluid reservoir (OEM 3403539) is a used genuine part, also called a brake fluid tank. It stores hydraulic fluid for the braking system; a cracked or leaking reservoir can cause a soft pedal or low-fluid warning. This reservoir fits BMW X3 models with the M54 or N52 six-cylinder engines. Make sure the mounting and hose connections match your existing setup before installing.
