Important information before updating the software

Diagnostic entries logged in diagnostic address 0075 will be repaired by a software update described in this
TSB. The Guided Fault Finding test plans should not be carried out and cannot be invoiced.

There will be extended inactive periods for some of the steps. You can work on a different vehicle during this
time. This is considered in the warranty accounting instructions.

CSwnen carrying out this TSB, time stamps are not required for billing under warranty.

A newly developed test program is used to input the SVM code. Please ensure that the tester being used has
the latest ODIS update. The new test program for software updates is included in ODIS software.

Note: The vehicle uses acoustic signals and flashing lights to indicate when user input is required during and
at the end of the test program.

Important: Please prepare the required USB-C sticks (see parts information) before starting the repair. The
update media can be used for multiple vehicles.

This update package also includes new software for the MIB3 infotainment system. Useful information for
MIB3 software updates can be found in TSB 2060523, 97 MIB3: Software Update Instructions.

perform the missing part of the update.
