Wear Data Stored In AWD Control Unit
WARNING: This page is about a different variant/trim than selected.
Wear data of the rear final drive is stored in the AWD control unit. When replacing the AWD control unit, this data must first be read out so that the data can be stored in the new AWD control unit. If the oil or the entire rear final drive assembly is replaced, the wear data must be reset in order to guarantee optimal functioning. When the AWD solenoid is replaced, the valve resistance value must be taught in again.
