2025 Audi A5/S5/Q5/SQ5 Software Update Flashing Issues

Audi has released TSB 2079692/5 to address various issues that may arise during the combined software update 03.10.00/C (28.13.01) KD2 for certain 2025 Audi A5, S5, Q5, and SQ5 models. This bulletin provides guidance for technicians on how to resolve problems such as aborted flashing procedures, unreachable control modules, and specific diagnostic trouble codes (DTCs) that can occur during or after the software update.

This TSB is crucial for ensuring successful software updates and resolving potential malfunctions that can impact vehicle functionality. Owners of affected 2025 Audi A5, S5, Q5, and SQ5 vehicles experiencing any of these symptoms should consult an authorized Audi service center.

Symptoms

Owners or technicians may observe the following symptoms related to the Audi A5 software update issues:

• Programming conditions not met: This can occur during the update process, often indicated by diagnostic code 0x0009.
• Control module communication errors: The onboard supply control unit (diagnostic addresses 00C5 and/or 8132) may become unreachable, often accompanied by fault message SDB20F0E or code 8118.
• Aborted flashing procedures: The software update flashing process may stop prematurely, particularly for the onboard supply control unit (diagnostic address 00C5).
• Post-update issues with rear lid: The rear lid may close without the power latching system, or fail to close properly after a successful software update.
• Instrument cluster messages: A warning message such as "Adaptive cruise assist currently unavailable" may appear.
• Incorrect control unit logging: One or more control units may log on incorrectly or become unreachable, especially when an SVM code is entered for the first time.
• Steering wheel vibration: While normal during the flashing procedure, persistent vibration after the update indicates an issue.
• File transmission freezes: The ODIS tester may display messages indicating that file transmission is frozen for longer than five minutes.
• Exterior door handle issues: Multiple electric exterior door handles may become unreachable after an aborted flashing procedure, indicated by diagnostic codes like 8060 or 8118.

Fault Codes / DTCs

This TSB identifies several diagnostic trouble codes (DTCs) and conditions related to the Audi A5 software update issues:

Code / Condition	Description / Associated Symptom	Diagnostic Address
0x0009	Programming conditions not met
8118, SDB20F0E	Control module cannot be reached	00C5 and/or 8132
8060	Flashing aborted	00C5 and/or 8132
8118	Diagnostic addresses	062A and 062B
8060 or 8096	Lost configuration, control units unreachable
9024 or ODS1008E	Connection issues (GSB bus times out)
8060, 8118, 8125, 8090, SDB20F0E	Control module cannot be reached	8117 and 006C
8060 or 8118	Multiple electric exterior door handles unreachable	4200, 4201, 4202, 4203

Diagnosis / Trigger Conditions

These issues typically arise during or after the combined software update 03.10.00/C (28.13.01) KD2. Specific triggers include:

• An error occurring during a partial update via a code.
• Problems with the SVM - Check vehicle configuration process.
• Information displayed on the ODIS tester indicating a fault.
• Aborted flashing procedures for TSB 2079690.
• The GSB bus timing out during communication attempts.
• Firewall settings on the workshop tester preventing necessary data downloads.

Repair Procedure Summary

To resolve these Audi A5 software update issues, technicians should follow specific steps outlined in TSB 2079692/5:

• For 0x0009 (Programming conditions not met): Erase the event memory and then perform the software update again.
• For 8118/SDB20F0E (control module cannot be reached at 00C5/8132): Perform a Terminal 30 reset of the onboard supply control unit for more than 15 minutes. Afterward, verify that diagnostic addresses 00C5 and 8132 are reachable and re-attempt the software update. If the control unit remains unreachable, replace the onboard supply control unit J519, activate it, perform a bus sleep cycle for over one hour, start a new ODIS session, and then directly perform the software update again.
• For 8118 (diagnostic addresses 062A and 062B): Refer to TSB 2080352, which addresses issues with reversible belt tensioners.
• For "Adaptive cruise assist currently unavailable" message: After the software update, ensure all vehicle doors and the rear lid are opened and closed once.
• For unreachable control units (general error, 8118/SDB20F0E): Attempt to restore communication capability using GFF (Guided Fault Finding). If this is unsuccessful, open a ticket with the Technical Assistance Center (TAC), noting the code on the affected control unit.
• For 8060 or 8096 (lost configuration): Perform a bus sleep cycle for at least 15 minutes, then repeat the procedure using the SVM code.
• For 9024 or ODS1008E (connection issues): Perform the update again. If it fails, contact the ICT administrator.
• For "File transmission freezes": Check the EdgeBox and firewall settings with IT support. Configure the firewall to allow communication on port 8080. If this is the first occurrence, verify firewall settings and re-enter the code.
• For 8060, 8118, 8125, 8090, SDB20F0E (8117/006C): Refer to TSB 2080613 for information regarding irregularities during KD2 combined software updates.
• For 8060 or 8118 (4200-4203): Refer to TSB 2080648 for issues where electric exterior door handles cannot be reached.

Audi emphasizes that further attempts can be made to update the vehicle to the new version. The procedure should be repeated until the software update is successful.

Important Warnings

Owners and technicians should be aware of the following critical information:

• "If a vehicle has already been updated partially using a code and an error occurred during the update, do not attempt to repair the vehicle via 'SVM - Check vehicle configuration'."
• "Please make absolutely sure to observe the information displayed on the tester before sending a support request."
• "Vibration of the steering wheel during the flashing procedure is a normal occurrence." This means it is not a fault unless it persists after the update.
• "This TSB is informational only and not applicable to any Audi Warranty." This indicates that any repairs related to this TSB may not be covered under standard warranty terms.

Owner Action

If you own a 2025 Audi A5, S5, Q5, or SQ5 and are experiencing any of the described Audi A5 software update issues, especially after a recent software update attempt, it is recommended to contact an authorized Audi service center. Provide them with details of the symptoms or any error messages you have observed. Since this TSB is informational and not covered by warranty, discussing potential costs with your service advisor is advisable.
