Spare Parts Requirements:
Actuators for Electric Parking Brake (34/09)
Vehicle Type:
Panamera S / Panamera Turbo
Model Year:
2010
Concerns:
Actuators for electric parking brake (referred to below as "EPB").
Information:
Spare parts requirements/repairs:
- Actuators with part-number index 01 are not available.
When vehicle production began, actuators with the part number 970.352.091.01 and ... 092.01 were installed for the EPB.
Modified actuators with a new part number have been installed since the middle of August 2009. The software for the EPB control unit has been updated accordingly for the modified actuators and the control unit part number is new.
Date of Introduction:
Mid-August 2009, as of VIN:
WP0AB2 A7 SAL 060328 USA WP0AC2 A78AL 090176 USA
Parts Info:
970.352.091.02 New/--> Actuator (left) 970.352.092.02 New/--> Actuator (right) 970.618.109.08 New/--> EPB control unit
Repairs:
The previously used actuators with part-number index 01 are not available for carrying out repairs on vehicles manufactured before the specified
VINs.
The actuators with part-number index 02 are now used instead of the unavailable actuators (part-number index 01).
When installing the new actuators, the old EPB control unit must be replaced with the control unit with part-number index 08 (see also ~-->
Technical Information '466200 Spare parts requirements: Control unit for electric parking brake (36/09)').
Information
The actuators can be differentiated (old/new and left/right) based on the part number engraved on the actuator.
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:
1 Replace both actuators (left and right side of the vehicle), see --> Workshop Manual '468519 Removing and installing spreader device (EPB
actuator)'.
2 Replace the old control unit with the control unit 970.618.109.08, see --> Workshop Manual '466219 Removing and installing control unit for
electric parking brake'.
