Used OEM BMW Brake Fluid Reservoir / Tank, part number 6889802. This genuine reservoir holds and supplies brake fluid to the hydraulic system, maintaining proper pressure for pedal feel and stopping force. A common failure symptom is a cracked or leaking tank, which can lead to a soft brake pedal or low fluid warning. Removed from a donor vehicle, this is the direct factory replacement for your BMW.
