Firstly ( assuming you have replaced the brake pads) you MUST replace the wear sensor with a new one. Lower drivers window, With door closed, lean thro open window and put ignition on without starting, leave for 15 minutes minimum, switch off, then start car. If this fails and you are unable to cancel warning via I drive button, then an appropriate scan tool will be required.

You may need to replace the sensors on the rear brake pads.

Per the BMW service manual you are supposed to replace the wear indicators with each brake job.

that has to be done by a dealership with a BMW specifiic scan tool

Ignition key must be “off”
• Press and hold the trip odometer reset button in the instrument cluster (left button), and turn the ignition key to the first position.
• Keep the button pressed for approximately 5 seconds until one of the following words appear in the display: “ OIL SERVICE, or “INSPECTION”, with “RESET”.
