Additional work on all-wheel drive vehicles after driving with faulty (non-engaging) drive (4' Series coupe, convertible, and Gran Coupe sedan)

IMPORTANT: If the vehicle has been shifted under engine power with a non-engaging drive system (e.g. faulty front prop shaft, or one output shaft is no longer engaging with the drive flange, rear axle differential faulty/no power transmission), it is mandatory to calibrate the transfer box after having repaired the prop shaft/output shaft(s).

Carry out calibration after having completed the repair using the diagnostic system via an applicable scan tool and information system, in control unit function - Functional check - Transfer box.
