One or both of the following concerns with the Audi MMI connect smartphone app or myAudi website is
present:
 The function “Warning messages" does not provide
new data when the user manually attempts to refresh
the data. An error message stating “The vehicle cannot
be reached” can be seen in the app and the myAudi
web site (Figure 1).
 The vehicle cannot be locked or unlocked with the app,
and an error message stating “A technical error
occurred” is displayed (Figure 2).
Note:
The customer must be verified as a Key User for these
functions to work.

Figure 2. Lock/unlock error.

Technical Background
The software in the connected data bus on board diagnostic interface (J533) (address word 0019), needs to be
updated to optimize functionality.
Tip: Not all errors in the MMI connect app indicate a
problem. For example, the message “The vehicle data
could not be updated” is displayed when the engine is on or
when the vehicle is being driven, as data is not refreshed
under these conditions (Figure 3).

message.

Production Solution
Optimized software for connected data bus on board diagnostic interface, J533 (diagnosis address 0019).

Service
Before starting any service work:
 That the customer will either need to be present with the phone during diagnosis or will need to provide the
myAudi.com login email address and password for the account so that the technician can log into the app on
his or her smartphone. If necessary, allow the customer to log in on the technician’s smartphone to keep the
login information private.
 Ensure that the plastic key tag with the vehicle code is available (check the glovebox).
1. Verify that the user is a Key User of the vehicle. In the
MMI, navigate to MENU >> Audi connect, then the
right option and choose Audi connect user
management. If the customer is a Key User, his or
her email address or myAudi username will be listed
(Figure 4).

Figure 4. Key User assigned with three
secondary users.
If no information is listed, the customer must go to www.audiusa.com/myaudi to become a Key User
by setting up a contract under the Audi connect user management area (log in and select “Audi
connect services”).
First verify that the customer is the owner of the vehicle by using the customer’s contract ID in
AcVDM. AcVDM can be accessed via www.accessaudi.com (App Links >> Audi connect >> AcVDM
myAudi Key User Verification Tool).
Note:
This TSB does not apply if there are no Key Users in the MMI. The vehicle owner must be a Key User
before the remote services can be used.

2. If the issue can be reproduced with the ignition off and the vehicle in sleep mode, check if the issue
persists with the ignition on and the engine off. If the data can be refreshed in the MMI connect app,
there are two possible solutions based on the hardware and software in the connected data bus on
board diagnostic interface, J533 (address word 0019):
The following applies to vehicles built before CW22/16.
If the hardware version is H10 or H11 and the software version is 0079, 1079, 2079 or 3079:
 Replace the connected data bus on board diagnostic interface, J533 (address word 0019).
 Using Guided Functions, select "Replace control unit".
 If the new replacement part does not have software version 4079 or higher, the control unit must
be updated using the SVM update instructions below.
For other hardware versions and all other software versions less than 4079:
 Update the connected data bus on board diagnostic interface, J533 (address word 0019) using the
SVM update instructions below listed in the table below.
The following applies to vehicles built after CW22/16.
If the software version is 0298, 305, 307 or 1298 (hardware version is not relevant):
 Update the connected data bus on board diagnostic interface, J533 (address word 0019) using the
SVM update instructions below listed in the table below. Vehicles built after CW45/16 use a
unique SVM code.
To access SVM, within ODIS start GFF >> Diagnosis >> Special functions >> Software Version
Management >> SVM code input.
Note:
ODIS Audi brand software of 2.7.5 or higher must be installed on the ODIS tester. The connected data bus on
board diagnostic interface, J533 (address word 0019), can be damaged during the update. It is recommended
that the new diagnostic interface VAS 6154 (with USB cable only) or VAS 5055 is used for the update. If the VAS
5054 diagnostic head is used, it must be used with the USB cable.
SVM software update of the connected data bus on board diagnostic interface, J533 (address word 0019):
1. Before updating the software, check for any open campaigns on the vehicle. There are open
campaigns that require the same software update for the connected data bus on board diagnostic
interface, J533 (address word 0019), with the potential of other control module updates. If there is an
open campaign for the vehicle, do not use the SVM code listed below. Instead, perform the software
update according to the open campaign.

2. If there is not an open campaign, update the vehicle with the SVM code listed in the table below. To
access SVM, within ODIS start GFF >> Diagnosis >> Special functions >> Software Version
Management >> SVM code input.

Note:
Due to the sensitive data transfer during the update, the update must be performed via USB cable. If Bluetooth is
used, the update will fail and make the hardware inoperable. Replacement of hardware due to a failed update with
Bluetooth will not be covered under warranty.

3. After the update, there may be additional SVM parameter settings required for the connected data bus
on board diagnostic interface, J533 (address word 0019), and other basic settings required for other
systems based on the equipment level of the car. Perform all additional work before moving on.

Verify that the condition has been resolved
1. Allow the MMI to fully initialize. Check for the Key User setting and verify that the customer is still listed as the
Key User. If no Key User is listed, the customer’s myAudi login and vehicle code will need to be re-entered.
2. Verify that the MMI has a good LTE signal to AT&T. The connected data bus on board diagnostic interface,
J533 (address word 0019) uses 3G GSM and not LTE. Despite this the LTE signal strength in the MMI will be
a good indicator of how strong AT&T’s service is in the area. Move the vehicle outside if needed to obtain a
stronger signal.
3. Remove the ODIS diagnostic head from the vehicle, roll up the windows, lock the car, and allow the car to go
to sleep (wait 2-3 minutes).
4. With the vehicle asleep, attempt to refresh the “Warning Messages” in the MMI connect app to see if the
function is restored. It can take the app 1-2 minutes to refresh the data. A successful test will yield no error
message.
