Technical Service Bulletin
With this new GEN3 system, the SOS light can take longer than previous Audi connect generations to turn green
after PDI. This new system utilizes a “white label” SIM card that is not preregistered to any USA-specific mobile
carrier at the factory. Audi of America partnered with Verizon as our preferred carrier for the GEN3 system for the
USA. For comparison, the 2nd Generation of the Audi connect system utilizes an AT&T SIM preregistered before
the car leaves the factory.

Production Solution
Not applicable.

Service
Since the 3rd Generation Audi connect system utilizes a SIM that is not preregistered at the factory, the SIM must
go through a “Registration and Pairing” (R&P) process after the ConBox/OCU flight mode is deactivated. The
R&P process typically takes 20 minutes under ideal conditions but often requires a subsequent sleep cycle after
flight mode deactivation, a GPS signal is obtained, and the car has been in an area with at least 3-bars of LTE.
In some cases, this process can take up to 1-2 hours, depending on the LTE signal strength, GPS reception, and
backend system availability. The SOS light will turn green once the embedded SIM (eSIM) has completed the
R&P process and is fully operating on Verizon’s LTE network.
For comparison, for the GEN2 system, the SOS light turns green almost immediately after flight mode is removed
because the R&P process is already completed before the vehicle arrives at the US port. With the GEN3 system,
the R&P process will always take longer than a GEN2 vehicle.
The SOS light, in most cases, will activate after the initial test drive following the PDI or after the vehicle has had
time to go through a long sleep cycle of 30 minutes or longer.
The steps below explain how the registration and pairing process works for GEN3 vehicles at a very high
level. This complex process is why the R&P can take a longer time than a GEN2 vehicle.
•

Step 1: ConBox: Flight mode (aka Airplane Mode) is deactivated during the PDI process, and the telephone
module and SIM activate. OCU: Flight mode is deactivated when the car is driven at least 25 miles or during
the total PDI test plan (the 25-mile threshold is set to 0 miles in this test plan).

•

Step 2: The SIM attempts to connect to Cubic in Europe using a roaming data connection that utilizes AT&T
or T-Mobile (Vodafone Roaming). If there is poor AT&T or T-Mobile service in the immediate area or inside
the service bay, this step could fail until the car is moved to an area with a stronger AT&T or T-Mobile signal.

•

Step 3: After the vehicle registers with Cubic, the device receives an eSIM profile for Verizon.

•

Step 4: Once the Verizon profile is downloaded, the device will disconnect from AT&T or T-Mobile and
attempt registration to Verizon’s LTE network. If there is poor Verizon service in the immediate area or inside
the service bay, this step could fail until the car is moved to an area with a stronger Verizon signal. A long
sleep cycle of 30 minutes or more may be needed.

•

Step 5: Next, the Verizon profile is successfully downloaded. The device will inform Cubic that it will always
use the Verizon network from that point forward (setting Verizon as the default network connection).

•

Step 6: Cubic will then activate the Wi-Fi profile for the device. At the same time, Cubic will activate dealer
demo mode in the Audi connect backend.

Step 7: Lastly, the MMI and Gateway modules should download the Audi connect licenses for PRIME and CARE
if the car has already received GPS reception (the vehicle must be placed outside or taken on a test drive). At
this point, barring any issues in the backend systems, the SOS light should turn green.
If you experience issues with the activation process, then follow the steps below:
1. If the SOS light does not turn green after the PDI test drive or after the car has been through a long sleep
cycle following the PDI test drive, allow the car to sit outside with the ignition on for 20-30 minutes with the
engine running. If this has already been done, then move to step 2.
2. Perform a long sleep cycle of 5 minutes or more. To do this, disconnect any ODIS testers, roll up the
windows and close the hood and trunk. Next, lock the doors. Doing this will allow the car to go to sleep
faster.
3. Turn the car on and check the status of the SOS light after 5-10 minutes.
4. After rechecking the system, repeat steps 1-3 a second time if the SOS light does not turn green.
5. If the SOS light does not turn green after the second time through steps 1-3, please perform a capacitive
discharge by disconnecting the vehicle 12V battery from the vehicle electronics for at least 60 seconds.

It is no longer required to remove the backup battery from the ConBox, as long as the capacitive
discharge is performed for at least 60 seconds while there is no emergency or roadside call active in the
vehicle. Removing the backup battery can damage the control unit due to electrostatic discharge.
1. Let the car sit for 60 seconds (or longer) with the 12v battery disconnected, reconnect the battery and turn on
the ignition.
2. Check and document the eSIM profile currently in use by the ConBox (OCU if A3/Q3/Q4). This can be
accomplished using ODIS. Selected “Checking IMSI number” under “Guided Functions” for diagnostic
address 0075.
Vodafone Bootstrap (Factory) Profile will have a 20-digit ICCID starting with “8988”.
Verizon Operation (Local) Profile will have a 20-digit ICCID starting with “8914”.
Take a screen shot of this value, write it down, or upload it to GFF Paperless.
3. Check the status of the SOS light. If, at this point, the SOS light does not turn green, open a web ticket with
the Audi Digital Business Support Team: https://audi.zendesk.com/. Please provide the IMSI, ICCID, and
EID using one of the methods mentioned in the previous step.

You will need to use a dealer email address to register for access to the web ticketing system. Using a
personal Gmail or Yahoo account will not allow you to register to the site. If this is not possible, then
please contact us at connect.support@audi.com so we can verify your dealer credentials and then
enable you to utilize your personal email to access the web ticketing system.
