2022-2026 Audi Overhead View Camera Fault TSB 2055188/14

Audi has issued Technical Service Bulletin (TSB) 2055188/14 to address customer complaints regarding inoperative, blurry, or fogged overhead view cameras. This issue can affect various 2022-2026 Audi models and is often accompanied by specific diagnostic trouble codes (DTCs) related to the driver assistance systems.

Symptoms

Owners of affected Audi vehicles may experience one or more of the following issues with their overhead view camera system:

• One or more overhead view cameras appear steamed up.
• The entire overhead view camera system does not function, either intermittently or statically.
• Individual overhead view cameras are inoperative.
• Multiple overhead view cameras are not working.

These symptoms can lead to problems with features like parking aid functionality, incorrect area view camera images, or faulty display modes such as 'Rear View'.

Fault Codes / DTCs

When diagnosing the overhead view camera issues, technicians may find one or more of the following DTCs stored in the driver assist systems control module (J1121, address word 00A5):

Code	Description	Module	Storage State
C12B102	Right peripheral camera, video wiring Signal error	00A5 - Front sensor for driver assistance systems	static / intermittent
B127E04	Left environmental camera faulty	00A5 - Front sensor for driver assistance systems	static / intermittent
B127D4B	Rear peripheral camera Excessive temperature	00A5 - Front sensor for driver assistance systems	intermittent / static
B127C4B	Front environmental camera Excessive temperature	00A5 - Front sensor for driver assistance systems	intermittent / static
B127E4B	Left environmental camera Excessive temperature	00A5 - Front sensor for driver assistance systems	intermittent
C12AF02	Rear peripheral camera, video wiring Signal error	00A5 - Front sensor for driver assistance systems	static / intermittent
B127F04	Right environmental camera faulty	00A5 - Front sensor for driver assistance systems	static / intermittent
C12AE02	Front peripheral camera, video wiring Signal error	00A5 - Front sensor for driver assistance systems	static / intermittent
C12B002	Left peripheral camera, video wiring Signal error	00A5 - Front sensor for driver assistance systems	static / intermittent
B200FFA	Internal malfunction	00A5 - Front sensor for driver assistance systems	static / intermittent
B127D04	Rear peripheral camera faulty	00A5 - Front sensor for driver assistance systems	intermittent / static
B127C04	Front environmental camera faulty	00A5 - Front sensor for driver assistance systems	intermittent / static
B127F4B	Right environmental camera Excessive temperature	00A5 - Front sensor for driver assistance systems	static / intermittent

Diagnosis and Repair Overview

The TSB outlines specific diagnostic and repair procedures based on the observed symptoms and stored DTCs. A critical step in all scenarios is ensuring the vehicle enters bus sleep after each check to reinitialize the overhead view camera system.

Scenario 1: Individual Camera Fogged or Blurry

If an individual overhead view camera is fogged up, or its image is cloudy or blurry, the issue may stem from a faulty camera, short circuit in the video cable, or water ingress. In such cases, the recommended action is to replace the fogged or blurry overhead view camera along with its adapter wiring harness.

Scenario 2: Multiple Camera DTCs Stored

When multiple DTCs related to various cameras are stored, the diagnostic process involves systematically isolating the fault. Technicians should first disconnect all cameras from the driver assist systems control unit (J1121). Then, each camera (-R243-, -R244-, -R245-, -R246-) must be connected individually, with a bus sleep cycle performed after connecting each camera branch. The camera system is activated, and the MMI screen is checked for correct image display while operating doors, hood, or trunk.

If the issue persists, all coupling points and coax cables between the J1121 control unit and the affected overhead view cameras should be inspected for loose connectors, pushed-back pins, corrosion, or damage. If no clear cause is found, technicians may swap individual overhead view cameras or video cable connections on the J1121 unit to further narrow down the problem. If the harness cannot be located, refer to TSB 2076264.

Scenario 3: Single Camera DTC Stored

If only a single DTC for one individual overhead view camera is logged, the process begins with performing a bus sleep cycle to reinitialize the J1121 control module. The overhead view camera system is then activated, and the MMI screen is checked for correct image display while operating doors, hood, or trunk.

If the specific DTC, such as an Audi e-tron camera fault, persists, technicians should inspect the coupling points and coax cables between the J1121 control unit and the affected overhead view camera (-R243-, -R244-, -R245-, -R246-) for any damage or loose connections. Similar to Scenario 2, if no cause is identified, swapping individual overhead view cameras or video cable connections can help pinpoint the fault. If the camera itself is not the problem, the wiring can be double-checked by swapping the coax wire at the J1121 side.

Important Notes for Technicians (and Owners)

• Bus Sleep Cycle: It is crucial that the vehicle enters bus sleep after each diagnostic step to properly reinitialize the overhead view camera system.
• J1121 Control Unit: Replacing the driver assist systems control unit (J1121) solely based on DTC B200FFA (Internal malfunction) will NOT resolve the customer complaint if other clear findings are absent.

Required Tools or Parts

While no special tools are explicitly listed, the repair procedures may involve replacing specific components:

• Overhead view camera units (-R243-, -R244-, -R245-, -R246-)
• Adapter wiring harness (for fogged/blurry cameras)
• Coax cables

Owner Action

If your 2022-2026 Audi is experiencing issues with its overhead view cameras, such as blurriness, fogging, or inoperation, and you suspect an Audi e-tron camera fault, it is recommended to schedule an appointment with an authorized Audi service center. They have the necessary diagnostic tools and expertise to follow TSB 2055188/14 and accurately diagnose and repair the problem.
