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 considered 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.
