2021-2022 Audi Overhead View Camera Inoperative TSB 2055188/3

If you own a 2021-2022 Audi and are experiencing problems with your overhead view cameras, such as a blurry picture or complete inoperation, you're not alone. Audi has issued Technical Service Bulletin (TSB) 2055188/3 to address these concerns, which are often accompanied by specific diagnostic trouble codes (DTCs).

This TSB provides detailed instructions for diagnosing and repairing issues related to the overhead view camera system, which is crucial for features like parking assistance. The Audi e-tron camera inoperative condition is a common complaint covered by this bulletin.

Symptoms

Owners of affected 2021-2022 Audi vehicles may observe the following symptoms:

• One of the overhead view cameras is inoperative.
• The picture from one of the overhead view cameras appears blurry or fogged up.

These symptoms often indicate an underlying issue with the camera system or its connections.

Fault codes / DTCs

When an overhead view camera issue occurs, one or more of the following Diagnostic Trouble Codes (DTCs) may be stored in the control module for driver assist systems, J1121 (address word 00A5):

Code	Description	Module
B127C04	Faulty	J1121
C12AE02	Video cable signal error	J1121
B127C4B	Excess temperature	J1121
B127D04	Faulty	J1121
C12AF02	Video cable signal error	J1121
B127D4B	Excess temperature	J1121
B127E04	Faulty	J1121
C12B002	Video cable signal error	J1121
B127E4B	Excess temperature	J1121
B127F04	Faulty	J1121
C12B102	Video cable signal error	J1121
B127F4B	Excess temperature	J1121
B200FFA	Internal malfunction (with symptom code 282648 or 282649)	J1121

These codes help technicians pinpoint the specific camera or component causing the problem, such as an Audi e-tron camera inoperative condition.

What the service bulletin says

Audi Technical Service Bulletin 2055188/3 outlines diagnostic steps and potential remedies based on the specific scenario:

• Single DTC for one camera: If only one DTC is logged for a single overhead view camera (R243, R244, R245, or R246), the technician should first perform a bus sleep cycle. If the DTC persists, the wiring harness between the J1121 control module and the affected camera should be inspected for loose connections, damaged pins, corrosion, or other damage. If no visual cause is found, swapping the camera with a new one or testing the video cable by plugging another camera into the J1121 module's port is recommended.
• Multiple DTCs for overhead cameras: When several DTCs are stored, it suggests a broader issue within the Topview camera system. This could be due to a faulty camera, a short circuit in the video cable, or water ingress. The diagnostic steps for a single DTC should be followed to identify the root cause.
• Blurry picture: If the camera picture is blurry, the TSB recommends replacing the adapter wiring harness to the camera and the fogged-up overhead view camera itself. The part number 4L0035576K is mentioned for a connector housing for the front area camera.

It's important to note that replacing the J1121 control module for these DTCs is generally not effective. A bus sleep cycle is required between each diagnostic step to reinitialize the control module and cameras.

What to do

If your 2021-2022 Audi is experiencing an inoperative or blurry overhead view camera, or if you have received a diagnostic report showing DTCs like B127C04 or B200FFA, it is recommended to schedule an appointment with an authorized Audi service center. Provide them with the symptoms you are experiencing and mention Technical Service Bulletin 2055188/3. This will help ensure that your vehicle receives the correct diagnosis and repair according to Audi's guidelines.
