Technical Service Bulletin
Service
A measure is not to be expected before the first quarter of 2025.
Please carry out the following workaround to resolve the complaint:
1. With the ignition turned on, switch to the guest user in the MMI.
2. Once this profile has loaded successfully, switch back to the original user.
3. Then lock the vehicle and leave it for 15 minutes (put into bus sleep mode).
If the issue still occurs, please work through the following steps:
1. Reset the MMI to factory settings.
2. Create a new myAudi user in the vehicle (as it was before being reset to factory settings).
3. After completing the setup for the new user, switch to the guest user.
4. Once the guest user has loaded successfully, switch back to the original user.
5. Then leave the vehicle for 15 minutes (put into bus sleep mode).
The issue is then resolved and the defrost function does not deactivate itself. Within 15 seconds of changing the
user in the vehicle, the MAX defrost function will continue to deactivate itself within the first five to ten seconds.
If settings were changed or new favorites stored on the MMI, it is recommended to perform the first three steps of
the above workaround again.
The standard auxiliary air conditioning enables the vehicle to be cooled before being driven in summer or heated
up in winter. The activation of the auxiliary air conditioning can be planned and by entering a departure time, it
can be started directly before a trip. The functions can be programmed and activated in the MMI and conveniently
switched on using the myAudi app. The auxiliary air conditioning works regardless of whether the vehicle is
currently being charged via the charging infrastructure or not – a prerequisite being that the battery is sufficiently
charged. The air conditioning can be started for a short time when unlocking the vehicle with the remote-control
key.
By warming the vehicle up before driving in the winter, the MAX defrost function on the air conditioner control
console can be replaced relatively well.
