2023-2024 Audi Night Vision Assist Fault DTC U110100

Symptoms of the Audi Night Vision Assist Fault

Owners of 2023-2024 Audi vehicles may experience a malfunction with their night vision assist system. The most common indication is a warning message displayed in the Audi virtual cockpit stating: "Night vision assist: fault. Please contact workshop". When this message appears, the night vision system typically becomes inoperative, and the camera image display may not function.

Fault Codes (DTCs)

When diagnosing the Audi night vision assist fault U110100, technicians will find the following diagnostic trouble code (DTC) stored in the Night Vision System -J853- (address word 0084):

Diagnostic Trouble Code	Fault Symptom	Storage State
U110100	Component protection active	Intermittent
U110100	Component protection active	Static

Diagnosis and Trigger Conditions

The root cause of the Audi night vision assist fault U110100 is identified as a software issue within the data bus diagnostic interface, specifically at diagnostic address 0019. This software anomaly leads to the "Component protection active" status being incorrectly logged, preventing the night vision system from operating as intended.

To confirm the issue, technicians should check the software version of the Data Bus On Board Diagnostic Interface, -J533- (diagnostic address 0019). If the current software version is 0025, then this Technical Service Bulletin (TSB) 2077875/1 is applicable for resolution.

Repair Procedure Summary

The recommended repair involves a software update to the diagnostic interface control unit (DA0019) to software version SW 0027. This update is performed using the Software Version Management (SVM) system.

1. Preparation: Before starting the update, ensure all instructions in TSB 2011732: 00 Software Version Management (SVM), operating instructions, are followed. For vehicles equipped with high-voltage components, it is crucial to unplug the high-voltage charging cable before entering the SVM code to prevent the high-voltage battery from charging during the update. Charging the high-voltage battery during this process can cause damage to the components.
2. Software Version Check: Verify that the Data Bus On Board Diagnostic Interface, -J533- (0019) has software version 0025. If it does, proceed with the TSB.
3. Update Process: Update the Data Bus On Board Diagnostic Interface, J533, via SVM. This requires using the "Flash" mode on the ODIS tester and entering the specific SVM code: ZGDOIP,19A025. The new test program for software updates is included in ODIS software available as of April 16, 2025.
4. Post-Update Steps: After the update is complete, it is essential to unplug the diagnostic connector and the charger from the vehicle. Then, start the engine and let it run for one minute, followed by locking the vehicle and waiting for five minutes. Finally, the diagnostic procedure can be completed via ODIS to delete any event memory entries created during the flashing process.

Important Warnings for Owners

• High-Voltage Vehicles: If your Audi is an electric or plug-in hybrid model, it is critical that the high-voltage charging cable is unplugged before any software update involving the SVM code is initiated. Failure to do so could lead to damage to high-voltage components.
• Third-Party Modifications: If your vehicle's software has been modified by third parties (e.g., tuning or retrofitting), this official software update may neutralize those previous modifications. Audi recommends informing your service center if any such modifications have been made.
• Declining the Update: If an owner declines this software update, it may lead to continued issues or restrictions with the use of the night vision system or other individual components. This information will be noted on the service order.

Affected Control Units and Software

The software update targets the Data Bus OBD Interface (diagnostic address 0019). The following software part numbers are associated with this control unit, all with a software version of 0025 and hardware version H06, which require updating:

• 4KE.907.468.M*
• 4KL.907.468.M*
• 4KR.907.468.M*

Warranty Information

This Technical Service Bulletin 2077875/1 is informational only if the vehicle is outside of its warranty period. For in-warranty repairs, the service number is 9035, and the damage code is 0039. Labor operations for the software update include 0151 0010 and 0151 0060, with time stated in the diagnostic protocol.

Production Solution

Audi implemented a production solution for this issue, introducing new software from week 50/23 onwards to prevent the Audi night vision assist fault U110100 in newly manufactured vehicles.
