2019-2025 Audi Overhead View Camera Malfunction TSB 2055188/11

Audi has issued Technical Service Bulletin (TSB) 2055188/11 to address concerns regarding individual overhead view cameras that are inoperative, or display a "picture is blurry or fogged up." This issue affects various 2019-2025 Audi models and can be accompanied by specific Diagnostic Trouble Codes (DTCs) related to an Audi overhead view camera blurry condition.

The TSB, identified as 90 24 23 2055188/11, supersedes an earlier bulletin, 90 24-15, dated July 19, 2024. It provides detailed guidance for technicians to diagnose and resolve the underlying causes of the camera malfunction, which often stems from deviations in the diagnostic capabilities of the driver assist systems control unit -J1121-.

Revision History

This Technical Service Bulletin has undergone several revisions to update information and procedures:

• Revision 11: Updated labor operations within the warranty section.
• Revision 10 (July 19, 2024): Revised service procedures and updated the disclaimer. This revision superseded the previous TSB 90 24-15.
• Revision 9 (July 8, 2023): Added MY25 e-tron GT to the header, revised the "Condition" section with an updated customer statement, revised service procedures, and updated warranty labor operations.

Symptoms

Owners may notice that their overhead view camera system is not functioning correctly. The common customer complaints include:

• "The overhead view camera does not work (sporadically or statically)"
• "One of the overhead view cameras is fogged up." These conditions indicate a problem with the overhead view camera system, potentially leading to a blurry or inoperative display.

Fault Codes / DTCs

When diagnosing this issue, technicians may find one or more of the following Diagnostic Trouble Codes (DTCs) stored in the driver assist systems control unit, -J1121- (address word 00A5):

Code	Description	Fault Type
B200FFA	Internal malfunction (symptom 282648 or 282649)	Internal Malfunction
B127C04	Front overhead view camera	Fault
C12AE02	Front overhead view camera	Video cable signal error
B127C4B	Front overhead view camera	Excess temperature
B127D04	Rear overhead view camera	Fault
C12AF02	Rear overhead view camera	Video cable signal error
B127D4B	Rear overhead view camera	Excess temperature
B127E04	Left overhead view camera	Fault
C12B002	Left overhead view camera	Video cable signal error
B127E4B	Left overhead view camera	Excess temperature
B127F04	Right overhead view camera	Fault
C12B102	Right overhead view camera	Video cable signal error
B127F4B	Right overhead view camera	Excess temperature

Important Warnings

Audi has issued specific warnings regarding the diagnosis and repair of this Audi overhead view camera blurry issue:

• "Replacing the driver assist systems control unit -J1121- (address word 00A5) because of DTC B200FFA Internal malfunction (symptom 282648 or 282649) will NOT fix the customer complaint." This means technicians should not automatically replace the control unit if only B200FFA is present, as it will not resolve the underlying problem.
• "Replacing the driver assist systems control unit -J1121- without clear findings will NOT resolve the issue." This reinforces the need for thorough diagnosis before replacing the control unit.
• "Please note that during the following checks, the vehicle must enter bus sleep after each step so that the overhead view camera system is reinitialized." This is a critical step in all diagnostic scenarios to ensure accurate reinitialization and testing of the camera system.

Diagnosis and Repair Procedure Summary

The TSB outlines specific diagnostic and repair procedures based on the symptoms and DTCs present. The root cause is often a deviation in the diagnostic capability of the driver assist systems control unit -J1121-.

Scenario 1: Individual Camera Fogged, Cloudy, or Blurry Image

If an individual overhead view camera is fogged up, or its image is cloudy or blurry, the issue may stem from a faulty camera, a short circuit in the video cable, or water ingress.

• Repair: If necessary, replace the affected fogged or blurry overhead view camera along with its adapter wiring harness. It is important to take clear pictures of the complaint for documentation.

Scenario 2: Several Camera-Related DTCs Stored

When multiple DTCs related to various cameras are stored, the diagnostic process involves isolating the faulty component for the Audi overhead view camera blurry problem:

1. Disconnect all cameras: Disconnect all overhead cameras from the driver assist systems control unit -J1121-.
2. Individual camera connection: Connect each camera individually to the -J1121- control unit.
3. Bus sleep cycle: After connecting each different camera branch, a bus sleep cycle must be performed to reinitialize the driver assist systems control unit -J1121-.
4. System check: Activate the overhead view camera system for each connected camera, operate the doors/hood/trunk (depending on the camera's position), and simultaneously check the MMI screen to ensure the image displays correctly and without interruption. This process helps identify the affected camera harness branch(es).
5. Cable and connector inspection: Once the faulty camera branch is identified, thoroughly inspect all coupling points and coax cables between the -J1121- control unit and the affected overhead view camera (-R243-, -R244-, -R245-, -R246-) for any loose connectors, pushed-back pins, corrosion, or damage.
6. Component swapping (if no cause found): If no obvious cause is located, further diagnostic steps include:
   • Swapping an individual overhead view camera (e.g., -R244- with -R245-) with another to rule out a faulty camera.
   • Swapping the video cable connection on the -J1121- control unit (e.g., video cable of -R244- with -R245-) to rule out a faulty video cable. The connector housing on the video cable must be removed for this step.

Scenario 3: Single Camera-Related DTC Stored

If only a single DTC is logged for one individual overhead view camera, follow these steps:

1. Bus sleep cycle: Perform a bus sleep cycle to reinitialize the driver assist systems control unit -J1121-.
2. System check: Activate the overhead view camera system, operate the doors/hood/trunk, and check the MMI screen for a correct and uninterrupted image.
3. DTC persistence and inspection: If the DTC persists and is identical to the initial one (otherwise, proceed to Scenario 2), inspect all coupling points and coax cables between the -J1121- control unit and the affected overhead view camera (-R243-, -R244-, -R245-, -R246-) for loose connectors, pushed-back pins, corrosion, or damage.
4. Component swapping (if no cause found): If no cause is found, perform the same component swapping measures as in Scenario 2:
   • Swap an individual overhead view camera (e.g., -R244- with -R245-) to rule out a faulty camera.
   • Swap the video cable connection on the -J1121- control unit (e.g., video cable of -R244- with -R245-) to rule out a faulty video cable.
5. Wiring verification: If no camera problem can be identified, double-check the wiring by removing the connector housing on the -J1121- side of the coax wire and swapping it with a camera at a different position. If the fault then follows the swapped coax wire, overlay the coax wire to the camera.
