This Technical Service Bulletin (TSB) 2079692/3, released on January 22, 2026, serves as an aid for technicians to diagnose and resolve these potential problems. The document outlines several scenarios, including specific error messages displayed on the ODIS tester, customer complaints, and the recommended solutions.

This TSB is crucial for ensuring proper functionality after a software update. If you are experiencing 2025 Audi A5 software update issues, it is important to understand the potential causes and the correct repair procedures.

Important Warnings for Technicians and Owners

Audi has issued specific warnings regarding the software update process. If a vehicle has already been partially updated using a code and an error occurred during the update, technicians are advised not to attempt to repair the vehicle via "SVM - Check vehicle configuration." Instead, they must carefully observe the information displayed on the ODIS tester before submitting any support requests. This prevents further complications and ensures proper diagnosis.

Symptoms, Fault Codes, and Solutions

This TSB 2079692/3 details several common scenarios that can arise during or after the software update, along with their respective solutions. These issues often manifest as specific messages on the ODIS tester or as direct complaints from the vehicle owner.

• ODIS Tester Message: "0x0009 Control module in after-run"

  • Complaint: Programming conditions were not met during the update process.
  • Solution: The event memory should be erased, and the software update procedure must be performed again without switching the ignition off and on.

• Complaint After Update: Rear Lid Power Latching System Failure

  • Complaint: The rear lid closes without its power latching system after a successful software update.
  • Solution: Technicians should refer to TSB 2080580, titled "55 Rear lid does not close properly after software update," for detailed instructions.

• ODIS Tester Message: "8118" and/or "SDB20F0E (control module cannot be reached)" (Diagnostic Addresses 00C5 and 8132)

  • Complaint: Flashing was aborted for the onboard supply control unit (DA00C5).
  • Solution: The onboard supply control unit should be replaced, then commissioned, and finally, the software update must be performed.

• ODIS Tester Message: "8118 Diagnostic addresses (062A and 062B)"

  • Solution: For issues related to reversible belt tensioners not being reached, identified by SVM error code 8118, technicians should consult TSB 2080352, "69 PSS Reversible belt tensioners cannot be reached identified in event memory SVM error code 8118."

• ODIS Tester Message: "8024"

  • Solution: This code indicates that an incorrect SVM code was entered. Technicians are reminded that multiple SVM codes exist, distinguishing between PPE and PPC systems.

• Complaint After Update: "Adaptive cruise assist currently unavailable"

  • Complaint: A message appears in the instrument cluster stating that the adaptive cruise assist system is unavailable.
  • Solution: After the software update, all vehicle doors and the rear lid must be opened and closed once to resolve this message.

• ODIS Tester Message: "8118" and/or "SDB20F0E (control module cannot be reached)" with General Error

  • Complaint: One or more control units log on incorrectly or cannot be reached, particularly when an SVM code is entered for the first time.
  • Solution: Technicians should first attempt to restore communication capabilities via GFF. If this fails, a ticket must be opened with the Technical Assistance Center (TAC), specifying the code on the affected control unit.

• ODIS Tester Message: "8060" or "8096"

  • Complaint: Possible causes include lost configuration after a software update or control units that can no longer be reached following an update.
  • Solution: A bus sleep cycle of at least 15 minutes should be performed, followed by repeating the procedure using the SVM code.

• ODIS Tester Message: "9024" or "ODS1008E" (Connection Negative Response from Server)

  • Complaint: The ODIS-S tester makes four attempts to establish a connection when the GSB bus times out.
  • Solution: The update should be performed again. If this second attempt is unsuccessful, the Technical Assistance Center (TAC) should be contacted.

• Complaint After Update: Steering Wheel Vibration

  • Complaint: While steering wheel vibration during the flashing procedure is normal, it persists after the update is completed.
  • Solution: For persistent steering wheel vibration, technicians should refer to TSB 2076547, "48 General information on flashing procedure (vibrating steering wheel)."

• ODIS Tester Message: File Transmission Freezes / "data required for the software update cannot be downloaded"

  • Complaint: The ODIS tester displays a message indicating that file transmission freezes for more than 5 minutes, or that the required software update data cannot be downloaded from the workshop server (EdgeBox). This is often due to firewall settings on the workshop tester.
  • Solution: The EdgeBox and firewall settings must be checked with IT administration, and the firewall should be configured according to ODIS release notes, specifically enabling port 8080.

• ODIS Tester Error Codes: "8060, 8118, 8125, 8090, SDB20F0E" (Control Module Cannot Be Reached) (Diagnostic Addresses 8117 and 006C)

  • Complaint: Flashing was aborted at diagnostic address 006C, and diagnostic address 8117 can no longer be reached.
  • Solution: Further information on irregularities when performing the KD2 combined software update on these diagnostic addresses can be found in TSB 2080613, "00 Workshop info: irregularities when performing KD2 combined software update on diagnostic address 8117+006C – PPE/PPC."

• ODIS Tester Error Codes: "8060" or "8118" (Possible Diagnostic Addresses: 4200, 4201, 4202, 4203)
