Technical Background
The 3rd Generation of the Audi connect system was first introduced into the MY20 B9 PI:
* MY22-26 A3 and Q3
* MY20 A4 and Ad.
*  MY21-26 Ad, A5, AG, A7, A8, Q5, Q7, Q8, Audi e-tron quattro, and Audi e-tron Sportback.
* MY22-26 Q4 e-tron, Q8 e-tron, e-tron quattro, e-tron Sportback, e-tron GT, and RS e-tron GT.

* MY25 Q6
With this GEN3/GEN4 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/GEN4 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 3 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.
¢«  $§tep 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).
¢«  $tep 2: The SIM attempts to connect to Cubic in Europe using a roaming data connection that utilizes AT&T or

T-Mobile (Vodafone Roaming). /f 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.
* §tep 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. /f 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.
«  $tep 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).
* $tep 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.
«  $tep 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. Performa 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, provided that 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. Letthe 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.
3. Check the status of the SOS light. If, at this point, the SOS light does not turn green, open a DBS Level 2

ticket via CIP or the web form link found in Access Audi. Please provide the IMSI, ICCID, and EID using one of

the methods mentioned in the previous step.
