An MMI System Update has to be performed.

MMI Update procedure

1. Connect a recommended battery charger to the designated charging posts in the vehicle.

Tip: To avoid false readings of the battery manager, don't charge the battery directly at its posts.

2. Eject possible inserted CDs from the CD changer in the glove compartment and load Update CD 4F0 906 961 AB in position 1.

3. All sound settings will be set to default after the update. Depending on the installed MMI components, further settings (Previous/Memory station list, stored CD name, directory entries and voice recognition name tags) may be lost.

Tip: Write down all settings to restore them after the update. Inform customers that they have to re-record their name tags.





4. Press and hold the MMI Control Head - buttons: Setup and Return simultaneously until the screen shown appears.





5. Press the lower right soft key of the MMI Control Head to enter the SW Update menu.





6. Use the central control knob of the MMI Control Head to select CD-ROM and then Standard.





7. The screen shown, which may take a few seconds to appear, shows the current software status of the MMI component in comparison to the inserted Update CD.





8. Scroll down the component list with the central control knob and select Start download.





9. Note and obey the displayed message to avoid component breakdowns. Scroll down the screen to accept the update shown with OK.





10. The MMI component update lasts between 15 and 60 minutes, depending on the installed components.





11. After initialization of the updated components, the screen shown (or a similar one) appears.

Tip: The displayed status Not OK and - is update related and not a fault. Please ignore and proceed.





If you scroll down the component list, you may discover that not all necessary component updates were performed in the first step (not all OK). In this case, select Try again to perform the missing component update.





If all necessary components are updated (0 NOK), select Restart MMI to reset the MMI system.





12. Eject Update CD 4F0 906 961 AB and re-insert removed CDs, if applicable.

13. Connect the VAS Tester to the vehicle and erase all sporadic fault codes.

14. Select 07 - Display/control unit and add 32 to the adaptation value of adaptation channel 2. The battery charge status will then be displayed again.

Tip: After the update, the battery charge display in the CAR menu is off by default.

15. Perform the required SVM Update using action code:

^ NA4FK730 for A6.

^ NA4EK730 for A8.
