The third-generation BMW X3 Mk3 (G01) (2017–Present) grew more upmarket and tech-laden on BMW’s CLAR platform, with a full Condition Based Service strategy underpinning its maintenance. That CBS system drives the main service reset, with the oil service the most frequent item to clear after fresh oil. A TPMS reset relearns tyre pressures after a rotation, the brake pad wear sensor reset is needed when new pads and sensors go on, and steering angle calibration follows alignment work. A replacement 12V battery must be registered to the car so the intelligent charging system treats it correctly — skip this and battery life suffers. Pick the procedure that fits your X3 from the list of resets shown directly below.
