2021-2025 Audi Connect Online Connection Fault TSB 2077616/1

Owners of certain 2021-2025 Audi A3, Q3, S3, and RS 3 vehicles may encounter an Audi Connect online connection fault following a workshop visit. This issue, detailed in Technical Service Bulletin (TSB) 2077616/1, can prevent various online services and remote functions from operating correctly.

This TSB specifically applies if your vehicle's last workshop visit occurred after March 2, 2025, and included a Vehicle Key Management System (VKMS) calibration. The problem stems from a software-related issue within Audi's IT infrastructure.

Symptoms of an Audi Connect Online Connection Fault

Owners may notice several issues indicating an Audi Connect online connection fault:

• Online Services: "all online services have been permanently down" since the last workshop visit.
• myAudi App: The "myAudi app has permanently had no connection to the vehicle."
• User Login: The vehicle user "cannot log in or be created."
• Remote Functions: Remote-controlled parking heating/cooling, remote departure time programming, and remote door unlocking may show "functionality -> no function."
• Charging: Remote-controlled high-voltage battery charging may be "functionality -> faulty."
• Traffic Information: Online traffic information reception and display may be "functionality -> faulty" or show "functionality -> no function."
• SOS Button LED: The emergency call LED in the roof module next to the SOS button "does not light up green."
• Online Services Configuration/Update: Configuration may be "functionality -> not adjustable," and system updates may show "functionality -> cannot be ended."

Fault Codes and Trigger Conditions

During diagnosis, a key indicator of this issue is ERROR CODE 33 appearing in the overall status of the VKMS calibration within Guided Fault Finding. This error signifies that the Vehicle Key Management System (VKMS) activation was not performed successfully.

This condition can occur if one or more of the following control units were involved in a "Replace control module" test program:

• 0019: Data bus diagnostic interface
• 005F: Control unit for information electronics
• 00C6: Charging unit for high-voltage battery
• 8107: Aerial module
• 0075: Emergency call module and communication unit

Important Warnings for Owners

• This TSB 2077616/1 is only applicable if your vehicle's last visit to the workshop was after March 2, 2025, AND the VKMS was calibrated during that visit. If these conditions are not met, this bulletin does not apply to your vehicle's symptoms.
• The fault can also appear after a "virtual replacement," where a control unit was not physically replaced but the "Replace control module" test program was performed.
• If, after the repair procedure, the LED in the roof module next to the SOS button still does not light up green, it indicates the emergency call system is not activated correctly. In this specific case, the workshop must contact Audi's Technical Assistance Center (TAC) and reference TSB 2077592 for further assistance.

Repair Procedure Summary

The repair for the Audi Connect online connection fault involves a multi-step process focused on recalibrating the VKMS:

1. Initial VKMS Calibration: The technician performs another VKMS calibration using the vehicle diagnostic tester.
2. Chassis Number Erasure: It is crucial to wait for the vehicle's chassis number to be automatically erased from Audi's IT infrastructure. This process occurs hourly.
3. Second VKMS Calibration: After the chassis number has been erased, the VKMS is calibrated again. This step is essential to ensure the chassis number is properly removed from the IT infrastructure. The successful outcome will be indicated by "VKMS data OK" or "VKMS data OK - FAZ002399E."
4. SOS Button LED Check: Finally, the technician checks the status of the LED next to the SOS button in the roof module. It should light up green for a few minutes after switching the ignition off.

If the initial VKMS calibration results in ERROR CODE 33, performing a second calibration immediately afterward is necessary to trigger the chassis number erasure process.
