2023-2026 Audi e-tron Overhead View Camera Inoperative TSB

This Technical Service Bulletin (TSB) 2055188/7, issued on November 15, 2023, provides comprehensive guidance for diagnosing and resolving issues with the overhead view camera system in various 2023-2026 Audi models. The TSB specifically targets situations where individual cameras are inoperative, or their displayed image is blurry or fogged up.

This bulletin supersedes TSB Group 90 number 23-30 dated June 20, 2023, incorporating updates such as revised technical background information about the J1121 control unit's diagnostic capabilities, clarified fault analysis and repair processes, and updated warranty information.

Symptoms

Owners of affected Audi vehicles may experience the following issues related to their overhead view cameras:

• "One of the overhead view cameras is inoperative."
• "One of the overhead view cameras is fogged up."
• The camera image appears "cloudy or blurry."

These symptoms directly impact the functionality of the overhead view camera system, which is crucial for parking assistance and other driver-assist features.

Fault Codes / DTCs

When an Audi e-tron camera inoperative condition occurs, technicians may find one or more of the following Diagnostic Trouble Codes (DTCs) stored in the J1121 driver assist systems control unit (address word 00A5):

Description	Fault	Video cable signal error	Excess 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, the internal malfunction DTC B200FFA may be present, often accompanied by symptom codes 282648 or 282649. It's important to note that due to diagnostic limitations of the J1121 control unit, the logged DTCs or blanked-out cameras on the MMI screen may not always directly correspond to the actual defective camera branch.

Important Warnings

Audi has issued specific warnings to technicians regarding the repair process to prevent incorrect diagnoses and denied warranty claims:

• NOTICE: "Replacing cameras (-R243–, –R244–, –R245–, –R246–) or the driver assist systems control module –J1121-will not resolve this customer complaint. Claims for replaced cameras or driver assist systems control modules may be denied."
• NOTICE: "Replacing the driver assist systems control module -J1121– will not resolve the customer complaint. Claims for replaced driver assist systems control module -J1121– may be denied."

These warnings emphasize the need for thorough diagnosis before replacing major components, as the issue often lies with wiring or individual camera units rather than the control module itself.

Diagnosis and Repair Procedure Summary

The TSB outlines several scenarios for diagnosing and repairing the Audi e-tron camera inoperative issue:

Scenario 1: Fogged, Cloudy, or Blurry Camera Image If an individual overhead view camera is fogged up or its image is cloudy or blurry, the technician should replace the affected camera along with its adapter wiring harness. Clear pictures of the complaint must be taken for documentation.

Scenario 2: Multiple DTCs Logged in J1121 When several or all of the listed DTCs are present, the diagnostic process involves systematically isolating the faulty camera branch. Technicians must disconnect all cameras from the J1121 control unit and then connect each camera individually. After each connection, a bus sleep cycle must be performed to reinitialize the J1121 unit. The overhead view camera system is then activated, and the technician checks the MMI screen for a correct and uninterrupted image while moving the doors, hood, or trunk (depending on the camera's position). Once the affected camera branch is identified, all coupling points and coax cables (R243, R244, R245, R246) between the J1121 unit and the camera are inspected for loose connectors, pushed-back pins, corrosion, or physical damage like pinched or kinked cables.

Scenario 3: Single DTC Logged for One Camera If only a single DTC related to an individual overhead view camera is logged, the technician performs a bus sleep cycle and activates the overhead view camera system, checking the MMI display. If the DTC persists, the coupling points and coax cables are inspected. If no wiring issue is found, the affected overhead camera is swapped with another. If the fault follows the camera, it is replaced. If the camera is not the issue, the wiring is double-checked by swapping the coax wire connector housing at the J1121 side with a different camera's position. If the fault follows the coax wire, the coax wire is overlaid to the camera.

Warranty Information

Warranty claims for this issue are covered for up to 48 months or 50,000 miles. For Audi Certified Pre-Owned (CPO) vehicles, G10 claim type applies. If the vehicle is outside warranty, this TSB serves as informational guidance only. The service number for this bulletin is 9083, with a damage code of 0040. Labor operations include checking, removing, installing, and adjusting the overhead view camera, with specific labor codes provided (9083 0199, 9083 19XX, 9083 1550). Diagnostic time is GFF (0150 0000) with a maximum of 150 Technical Units (TU).

What Owners Should Do

If you experience an Audi e-tron camera inoperative issue, or notice blurry or fogged images from your overhead view cameras, it is recommended to contact an authorized Audi service center. Provide them with details of the symptoms you are experiencing. The dealership technicians are equipped with the latest diagnostic tools and information from this TSB to accurately diagnose and repair the issue.
