What does this part do?
The transfer case receives power from the transmission and sends it to both the front and rear axles. This can be done with gears, hydraulics, or chain drive. On some vehicles, such as four-wheel-drive trucks or vehicles intended for off-road use, this feature is controlled by the driver. The driver can put the transfer case into either “two-wheel-drive” or “four-wheel-drive” mode. This is sometimes accomplished by means of a shifter, similar to that in a manual transmission. On some vehicles this may be electronically operated by a switch instead. Some vehicles, such as all-wheel-drive sports cars, have transfer cases that are not selectable. Such a transfer case is permanently “locked” into all-wheel-drive mode.On the BMW 3 and 5 series sedan the transfer case is chain driven and the transfer case is engaged “on the fly ” or when the vehicles sensors compute the necessity or demand such as if you were slipping in the snow or wet road condition ,the servomotor or actuator would be energized causing the transfer case to engage
Why did it break?
The servomotor failure ?can be caused by many different reasons ,Some things to look in to would be matching tire sizes or faulty speed sensors which can cause the electronic system to read faulty signals causing abrupt and un-necessary transfer case engagement , Constant poor driving conditions and abuse of the vehicle have also been known to cause the failure .
