2021-2025 Audi A3/S3/RS3/Q3 Connect No Online TSB

Audi has released Technical Service Bulletin (TSB) 2077616/2 to address a specific issue where 2021-2025 Audi A3, S3, RS3, and Q3 vehicles may lose their online connection after a workshop visit. This TSB, released on May 6, 2025, details a software-related problem with Audi Connect services and provides a temporary workaround for technicians.

This bulletin is a revision (Revision 2) of an earlier publication from April 14, 2025, indicating updated instructions for the repair process. The core problem is a software-related issue within Audi's IT infrastructure that can prevent the Vehicle Key Management System (VKMS) from activating successfully.

Important Warnings for Owners

This TSB 2077616/2 applies only under very specific conditions. Your vehicle must have had its last workshop visit after March 2, 2025, and the VKMS must have been calibrated during that visit. If these conditions are not met, this TSB may not be relevant to your vehicle's symptoms.

Furthermore, if, after the repair procedure, the emergency call LED in the roof module next to the SOS button does not light up green, it means the emergency call system is not activated correctly. In this critical safety scenario, your service center must contact the Technical Assistance Center (TAC) immediately, referencing TSB 2077616/2.

Symptoms of No Online Connection

Owners of affected 2021-2025 Audi A3, S3, RS3, and Q3 vehicles may notice several issues related to their Audi Connect services being unavailable after a recent service appointment. These symptoms include:

• "all online services have been permanently down"
• The myAudi app has "permanently had no connection" to the vehicle.
• The vehicle user "cannot log in or be created."
• The emergency call LED in the roof module next to the SOS button "does not light up green."

These issues can affect various functions, such as remote parking heating/cooling, remote departure time programming, online services configuration and updates, traffic information reception, and remote door unlocking.

Fault Codes and Diagnosis

During diagnosis, technicians may find that the Vehicle Key Management System (VKMS) activation was not performed successfully. Specifically, in the Guided Fault Findings, one or more control units may be confirmed with "ERROR CODE: 33". This error code typically appears for components such as:

• Information electronics 1
• Emergency call module and communication unit
• Antenna module

This "ERROR CODE: 33" indicates a problem with the VKMS calibration for these critical systems. The issue can occur if a VKMS calibration or a "Replace control module" test program was performed on the vehicle after March 2, 2025.

Repair Procedure Summary

Audi's service procedure for resolving the "2021-2025 Audi A3/S3/RS3/Q3 Connect No Online TSB" involves a multi-step process to correctly calibrate the VKMS and restore online functionality:

1. Initial VKMS Calibration: Perform a new VKMS calibration using the vehicle diagnostic tester. This step is crucial, even if the first calibration resulted in "ERROR CODE 33", as it initiates the process for the chassis number to be erased from Audi's IT infrastructure.
2. Waiting Period: After the initial calibration, the technician must wait for the chassis number to be automatically erased from the manufacturer's IT infrastructure. This erasure process occurs every hour on the hour. The technician must wait until the full hour has passed (on the hour plus 1 minute) before proceeding.
3. Second VKMS Calibration: Once the chassis number has been erased, the VKMS must be calibrated again. This second calibration should result in a successful status, such as "VKMS data OK" or "VKMS data OK - FAZ002399E". If any control unit still shows a different status, the VKMS must be calibrated again after switching terminal 15 off and on.
4. Check SOS LED Status: Finally, the technician will check the status of the LED in the roof module next to the SOS button. After switching the ignition on and off, this LED should remain lit green for a few minutes. If it does not, the emergency call system is not correctly activated, and the Technical Assistance Center (TAC) must be contacted.
