specified VINs.
The control unit with part-number index08 is now used instead of the unavailable control unit (part-number index 07).
When installing the new control unit, the old actuators must be replaced (because of the modified control unit software) with actuators with

Check the current control unit part number when installed: --> PIWIS Tester II 9818 must be connected, then select --> 'Control units' --> 'Parking brake' and press --> [F12].
Old and new actuators and control units must not be installed together. Work Procedure:
