The "transfer case" is designed as an active all-wheel drive system that is dynamically adapted to the
respective driving state.
Power transmission between the front and rear axle is controlled electronically via the "all-wheel
drive servomotor (transfer case)" and themulti-plate clutches integrated in the transfer case.
? On all-wheel drive vehicles, the drive train can become strained at low speeds and when the
steering is turned sharply when "Off-roadmode" is activated, depending on design.
? Under extreme conditions, the drive train can also become strained when "Off-roadmode" is
deactivated.
? Customers with little experience with all-wheel drive vehicles can interpret this behavior as a
fault, which in turn can result in incorrect diagnoses in the workshop.
Remedial
action:
Customer complaint to be checked:
? Rough-running engine or
? thevehicle vibrates or
? theengine jerks under load/during acceleration.
