2019-2026 Audi Overhead View Camera Faults and DTCs

Symptoms

Owners of affected Audi models may experience issues with their overhead view cameras. These symptoms include:

• "One of the overhead view cameras is inoperative."
• "One of the overhead view cameras is fogged up."
• The image from an overhead view camera appears cloudy or blurry.
• The MMI screen may display a blanked-out camera image, even if the camera itself is not the primary fault.

Fault Codes / DTCs

Technicians may find one or more of the following Diagnostic Trouble Codes (DTCs) stored in the driver assist systems control unit, identified as -J1121- (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, DTC B200FFA, indicating an "internal malfunction" with symptom code 282648 or 282649, may be stored.

Diagnosis / Trigger Conditions

The driver assist systems control unit -J1121- may store one or more of the listed DTCs. Due to diagnostic limitations of the -J1121- control unit, multiple DTCs might appear even if only one camera is faulty. The displayed blanked-out camera on the MMI screen might not accurately indicate the defective camera branch.

This Audi e-tron overhead camera fault can manifest as a single DTC for one camera, or multiple DTCs for several cameras. Proper diagnosis is crucial to identify the root cause, which could be the camera itself, its wiring, or the control unit.

Important Warnings

Repair Procedure Summary

Audi Technical Service Bulletin 90 24 05 2055188/8 outlines specific procedures based on the observed symptoms and stored fault codes. The bulletin supersedes Technical Service Bulletin Group 90 number 23-55 dated November 15, 2023.

Scenario 1: Fogged or Blurry Camera Image

If an individual overhead view camera is fogged up or produces a cloudy or blurry image, the technician should replace both the affected camera and its adapter wiring harness. Clear pictures of the complaint must be taken for documentation.

Scenario 2: Multiple DTCs Stored

When several or all of the listed DTCs are present in the driver assist systems control unit -J1121-, a more detailed diagnostic approach is required:

1. Isolate Cameras: Disconnect all cameras from the -J1121- control unit.
2. Individual Testing: Connect each camera individually back to the -J1121- control unit.
3. Bus Sleep Cycle: After connecting each camera, perform a bus sleep cycle to reinitialize the -J1121- control unit.
4. Image Verification: Activate the overhead view camera system and move the vehicle's doors, hood, or trunk (depending on the camera's position) to check if the image displays correctly and uninterrupted on the MMI screen. This helps identify the specific faulty camera branch.
5. Wiring Inspection: Once the faulty camera branch is identified, inspect all coupling points and coax cables between the -J1121- control unit and the affected overhead view camera (-R243-, -R244-, -R245-, -R246-). Look for loose connectors, loose or pushed-back pins, corrosion, or physical damage like pinched, overbent, or kinked cables.

Scenario 3: Single DTC for One Camera

If only a single DTC is logged for one individual overhead view camera without other related DTCs:

1. Reinitialization: Perform a bus sleep cycle to reinitialize the -J1121- control module.
2. Image Verification: Activate the overhead view camera system and move the vehicle's doors, hood, or trunk to check if the image displays correctly and uninterrupted on the MMI screen.
3. Wiring Inspection: If the DTC persists and matches the initial fault, 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, pins, corrosion, or damage.
4. Camera Swap: If no wiring problem is found, swap the affected overhead camera with another camera from the vehicle. If the fault then follows the swapped camera, replace the affected camera.
5. Coax Wire Overlay: If the fault follows the coax wire after swapping, overlay the coax wire to the camera.
