26... Additional work on four-wheel drive vehicles after driving with defective (non-engaging) drive

IMPORTANT: If the vehicle has been moved under engine power with a non-engaging drive system (e.g. front propeller shaft defective and no longer engaging with the front differential or 1 output shaft no longer engaging with drive flange), it is imperative that the transfer box is calibrated after repairing the propeller shaft/output shaft(s).

After completing repairs, perform calibration using BMW diagnosis and information system and selecting: Control unit function → Function check → Transfer box.
