To reset the disc brake warning light on a 2004 BMW 325i, you typically need to use a diagnostic tool or follow a manual reset procedure. If you have a diagnostic scanner, connect it to the OBD-II port and clear the fault codes. Alternatively, you can turn the ignition to the "on" position without starting the engine, then press the brake pedal three times. If the light persists, ensure that the brake pads are properly installed and that the brake fluid level is adequate.
