2025-2026 Audi A5/A6/Q5/S5 Reversing Camera Control Unit TSB

Audi has issued Technical Service Bulletin (TSB) 2078367/3 to provide guidance for technicians on replacing specific control units related to the vehicle's camera systems. This TSB, released on January 9, 2026, is crucial for maintaining the functionality of the reversing camera system control unit J772 and the control unit for overhead view camera J928 in affected vehicles. The reference number for this bulletin is 2078219.

The primary reason for this TSB is to address software issues that necessitate the use of new part versions for these critical camera control units. Owners of a 2025-2026 Audi A5, A6, Q5, or S5 who experience problems with their reversing camera or overhead view camera systems should be aware of this bulletin, as it outlines the correct repair procedure involving specific part replacements and software updates. This TSB is particularly relevant for issues affecting the Audi A6 reversing camera control unit.

Why This TSB Is Important

This TSB is vital because it directly impacts the functionality and reliability of your vehicle's camera systems. Due to inherent software issues, older versions of the reversing camera system control unit J772 and the Peripheral camera system control unit J928 cannot be properly supported or function optimally. Audi has developed new part versions to resolve these software conflicts and ensure seamless integration with the vehicle's baseline systems.

The updated control units require additional start-up steps to guarantee compatibility and proper operation. This means that simply replacing the hardware is not enough; a specific diagnostic and programming sequence must be followed. The TSB ensures that technicians have the correct information to perform these replacements and software updates accurately, preventing potential future issues and restoring full camera system functionality.

Revision History

This Technical Service Bulletin has undergone several revisions to ensure accuracy and comprehensive coverage:

• Revision 1 (06/27/2025): Initial publication of the bulletin.
• Revision 2 (10/17/2025): Revised the header to include additional models and modified the part order guide table.
• Revision 3 (Undated): Revised the condition section by adding a model table and updated the service verbiage.

Important Notices

Audi has included specific notices for technicians regarding the application of this TSB:

• TSB Application: This TSB is only applicable and must only be used if a technician is specifically instructed to refer to it by ETKA. This instruction typically occurs when replacing the reversing camera system control unit -J772- or the Peripheral camera system control unit -J928-.
• New Model Launch Repair Authorization: This bulletin may apply to vehicles still within their new model launch repair authorization period. For such vehicles, the workshop must create a case with the Technical Assistance Center (TAC) to obtain repair authorization. The TSB number (2078367/3) must be referenced in the first line of the TAC case.

Symptoms and Technical Background

While the TSB does not explicitly list owner-facing symptoms, the underlying issue stems from software incompatibilities within the reversing camera system control unit J772 and the Peripheral camera system control unit J928. These software issues prevent the proper functioning of the camera systems, which could manifest as intermittent operation, display errors, or complete failure of the reversing camera or overhead view camera. The purpose of this TSB is to provide a definitive solution by ensuring that only the latest, compatible part versions are used for replacement.

Audi's technical background explanation states that due to software issues, it is only possible to supply new part versions for these control units. The new part versions of the reversing camera system control unit -J772- or Peripheral camera system control unit -J928- require additional start-up steps to ensure compatibility with the vehicle baseline.

Repair Procedure Summary

Technicians must use a provided table to determine the correct vehicle model and camera system version (PR number) to identify the suggested part version/basis in ETKA. The instructions for ordering and starting up the control unit vary slightly depending on the specific PR number and the original part version.

Here's a summary of the repair steps:

Scenario 1: Replacing part number with index H (PR number KA2 / KA4)

If the original part number for the reversing camera system control unit J772 or Peripheral camera system control unit J928 had an index H and the vehicle has PR numbers KA2 or KA4, the discontinued part should be replaced with part number 85E980568Q. The following start-up steps are required:

1. Activate New Component: The new control unit must be activated using the
