Repair procedure

1. Manual software update for AED control unit (078E) via red menu

Please skip step 1 if the Android control unit (078E) already has software version 0621.

The AED control unit can only be updated via the red menu in the MMI.

Insert the USB update medium in the USB connection (see parts information for part number).
Select the red menu by pressing the following buttons:

Select “Update” and the source in which you have inserted the update medium (USB connection). Use the volume control to do this. All control units to be
updated (AED) are shown; scroll all the way down and start the update.

Once the manual update has been successfully completed, leave the red menu entirely before starting a diagnostic session.
Please make absolutely sure to leave the USB stick inserted. The correct time to remove the USB stick is described further down.
¢ The MMI will now restart.

« Wait until the MMI has fully initialized. The home screen must be complete and display all apps.

¢ Please restart the system by pressing and holding the volume control for 10 seconds.

¢« Open the notification center and switch to the “Audi connect notifications” tab.

« — Itmay take several minutes for further information to appear. Please wait.

* Please note: This procedure will only work if the USB stick is still inserted.

* Please wait (approx. 5 min.) until the download is complete.

Now remove the USB stick.

« Restart the system by pressing and holding the volume control.

* Check whether the update was successful by calling up the notification center / Audi connect notifications.
