2019-2026 Audi Overhead Camera System Fault TSB

Audi has issued Technical Service Bulletin (TSB) 2076264/5, released on January 30, 2026, to address common issues with the overhead view camera system in a wide range of models from 2019 to 2026. This bulletin outlines detailed diagnostic procedures and repair steps for conditions such as a steamed-up camera or a completely non-functional system. Owners experiencing an Audi overhead camera fault should be aware of this TSB.

Revision History of TSB 2076264/5

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

• Revision 5: Updated the verbiage for the Condition and Measure sections.
• Revision 4 (December 3, 2025): Revised the Warranty section, specifically updating accounting instructions.
• Revision 3 (October 24, 2025): Revised the header to include additional model years.

Symptoms of an Overhead Camera Fault

Owners may notice one or more of the following issues with their vehicle's overhead view camera system, indicating a potential Audi overhead camera fault:

• Steamed-up Camera: One of the overhead view cameras appears "steamed up," obscuring the image or making it blurry.
• System Malfunction: The entire overhead view camera system "does not work," which can manifest as an intermittent or static issue.
• Individual Camera Failure: A single overhead view camera "does not work," either intermittently or constantly.
• Multiple Camera Failure: Several overhead view cameras "do not work" correctly.

These symptoms often point to a problem within the driver assist systems control unit J1121 or related components.

Diagnostic Trouble Codes (DTCs)

When an Audi overhead camera fault occurs, one or more of the following Diagnostic Trouble Codes (DTCs) may be logged in the driver assist systems control unit -J1121- (diagnostic address 00A5):

Position	Defective	Video cable signal malfunction	Excessive temperature
Front overhead view camera	B127C04	C12AE02	B127C4B
Rear overhead view camera	B127D04	C12AF02	B127D4B
Left overhead view camera	B127E04	C12B002	B127E4B
Right overhead view camera	B127F04	C12B102	B127F4B

Additionally, an internal malfunction code may be present:

• B200FFA: Internal malfunction, symptom 282648/282649.

These DTCs help technicians pinpoint the exact nature of the camera system issue, whether it's a defective camera, a video cable signal problem, or an internal control unit malfunction.

Prerequisites for Diagnosis and Repair

Before performing any repairs related to TSB 2076264/5, specific conditions must be met to ensure proper diagnosis and resolution:

• Campaign 90TV Recall: It is mandatory that the Campaign 90TV recall has already been performed on the vehicle. If not, this recall must be completed first.
• J1121 Control Unit Software: The software on the driver assist systems control unit J1121 must correspond with one of the following versions for diagnostic address 00A5 (Front sensors for driver assistant systems): 0511, 0385, or 0367.

Important Warnings for Owners and Technicians

Audi has issued several critical notices within TSB 2076264/5 that owners and technicians must heed:

• Bus Sleep Mode for Reinitialization: "Please note that during the checks the vehicle must enter bus sleep mode so that the overhead view camera system is reinitialized." This action is crucial for proper system reset. "Replacing driver assist systems control unit -J1121- without clear findings will NOT resolve the issue."
• Model-Specific Repair Steps: "Must be observed! Step 3 consists of two parts: Step 3.1 only applies to the A6 / A7 / A8 Step 3.2 only applies to the Q7PU / Q8 / e-tron / e-tron GT." It is vital to follow the correct procedure for your specific vehicle.
• Conditional Video Cable Replacement: "The video cables should only be replaced if the issue persists after replacing the exterior mirror mountings (refer to step 2)." This prevents unnecessary parts replacement.
• Persistent Issues: "Should the complaint persist after completing this TSB, please submit a technical repair query to Technical Assistance Center (TAC)." This ensures that complex or unusual cases receive further expert guidance from Audi.
• Warranty Information: "If the vehicle is outside of any warranty, this Technical Service Bulletin is informational only," meaning repairs may not be covered under warranty.

Detailed Repair Procedure

The repair process detailed in TSB 2076264/5 involves several steps, depending on the specific symptoms and diagnostic findings. The overall goal is to address the root cause of the Audi overhead camera fault.

Step 1: Checking Repair History

Before proceeding with any physical repairs, technicians must review the vehicle's repair history. This check determines if any of the subsequent repair steps (Step 2, Step 3.1, or Step 3.2) have already been performed. If previous repairs are documented, technicians should continue with the necessary remaining steps.

Step 2: Replacing Exterior Mirror Mountings

If indicated by the diagnostic process, both exterior mirror mountings must be replaced. This procedure should be performed according to the detailed instructions provided in the Workshop Manual. This step addresses potential issues stemming from these components that could affect camera function.

Step 3: Replacing Video Cables (Model-Specific)

This is a critical step, which is divided by vehicle model line to ensure the correct components are addressed.

Step 3.1: Applicable to A6, A7, and A8 Models

If the Audi overhead camera fault persists after Step 2, technicians should replace the wiring harness for both the driver door and the front passenger door. The specific components for these wiring harnesses are part numbers XXX.971.029.XX (for the driver door) and XXX.971.030.XX (for the front passenger door). These parts are referenced in diagrams 972-033 / 972-330 and 972-035 / 972-350, respectively. Figure 1 and Figure 4 in the TSB illustrate these wiring harnesses and their connections within the door structure.

Step 3.2: Applicable to Q7PU, Q8, e-tron, and e-tron GT Models

For these models, if the problem continues after Step 2, all video cables between the driver assist systems control unit J1121 and the left and right overhead view cameras (-R244- and -R245-) must be replaced. Technicians are instructed to use specific adapter cables from ETKA diagram 971-805. These adapter cables are designed for the vehicle interior wiring harness, connecting to the front and rear cameras, and to the left door coupling point TTVL and the right door coupling point TTVR. Figure 2 in the TSB provides a visual guide to these adapter cables, showing their various connector versions (Items 1-5 define adaptation, Item 6 determines length). Figure 3 shows the routing of the interior wiring harness within the vehicle chassis. It's important that the connectors are unplugged from the faulty cable, but the cable itself must remain in the vehicle, as detailed in parts bulletin 0-413.

Required Tools and Parts

Specific parts and diagrams are referenced for this repair:

• Wiring Harnesses (for A6, A7, A8): Part numbers XXX.971.029.XX (driver door) and XXX.971.030.XX (front passenger door) are required. These are detailed in diagrams 972-033 / 972-330 and 972-035 / 972-350.
• Adapter Cables (for Q7PU, Q8, e-tron, e-tron GT): Adapter cables from ETKA diagram 971-805 are necessary. These cables are designed for the vehicle interior wiring harness.
• Parts Bulletin: Reference is made to parts bulletin 0-413 for specific instructions regarding cable replacement.
