Service

Important information before updating the software

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

Sire 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.

* When carrying out this TSB, time stamps are not required for billing under warranty.
* Anewly 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, 91 MIB3: Software Update Instructions.

Repair procedure

Software update for emergency call module (0075), gateway (0019) and information electronics (005F)
Use the function “SVM - Authorized Multiple Code Entry” in “Flash” mode.

IMPORTANT: For the new software update program, the following SVM code must be entered exactly, including commas and without spaces
(recommendation: scan QR code with hand-held scanner or copy and paste the SVM code chain).

DUCDTCPRO075MLB,FLIGHTONO0075MLB,ZGDOIP,CL3BPA001US,19A027,19B027,TGU1MDMVB,CL3BPA002US,FLIGHTOFF0075MLB

The test program initially prompts you to use a USB medium (see parts information for part number).

The automatic execution of software updates results in inactive time. This is taken into account in the warranty accounting instructions.

The USB-C stick can be removed after completing the program.

Note: If the procedure has been interrupted, please repeat step 1. The test program will then automatically perform the missing part of the
update.

2. Bus sleep mode

Put the vehicle in bus sleep mode after performing the software update.
Then switch the ignition back on and start the MMI.

3. Check emergency call LED

Check whether the emergency call LED in the roof module lights up in green again.

If the LED does not turn green, please refer to TSB 2079652 Emergency call LED in roof module not lit up in green.

4. End diagnostic session and send off diagnostic log online.

Warranty
When carrying out this TSB, time stamps are not required for billing under warranty.
You are therefore permitted to work on other vehicles at the same time. The update can also be performed by non-productive personnel.

The Guided Fault Finding test plans should not be carried out for diagnostic entries that are repaired by performing this TSB and cannot be
invoiced.

Claim Type: * — If the vehicle is outside of any warranty, this Technical Service Bulletin is informational only.
