Deactivate the “Automatic online map update” function in the MMI via “Settings” >> “System update”. Not
doing so could cause the following update to fail.
7.
If the vehicle has zFAS Var B/C installed, please insert the SD Card 4N0906961AR into the SD Card
reader of the vehicle (please see TSB 2056558: 91 MIB2+ Software Update Instructions for further
information).
Tip: This step is not required for zFAS Var A!
8.
Update the zFAS application software using SVM Code FASISKD4A002 (this update should take about 30
minutes).
Note:
Important: Always start the update out of ODIS. Please do not perform the update via the red
engineering menu (method 2) unless you have been given prior approval from TAC.
9.
Exit the flash context in ODIS. Otherwise, it will not be possible to execute the following steps.
10 Update the zFAS’ peripheral control modules using SVM code FASISKD4A003 (this update should take
between 20min and 30min).
11. Let the vehicle perform a bus sleep cycle:
 Exit the flash context
 Switch the vehicle’s ignition off
 Remove the battery charger and diagnostic interface dongle from the vehicle.
 Close the hood, trunk, all doors and lock the vehicle.
 Wait approximately six minutes without handling the vehicle.
Tip: After the update procedure, DTC U110100 (Component protection active (active/static)) will be entered
