When diagnosing this issue, technicians will find the following Diagnostic Trouble Code (DTC) stored in the Night Vision System -J853- (address word 0084):

This DTC can appear as either an intermittent or static fault.

Technical Background

The root cause of the Audi night vision U110100 fault is identified as a software issue within the Data Bus On Board Diagnostic Interface, specifically at diagnostic address 0019. This software anomaly triggers the "Component protection active" status, preventing the night vision system from operating correctly.

Repair Procedure Summary

The repair for the Audi night vision U110100 fault involves a software update to the diagnostic interface control unit (DA0019). The new software version is SW 0027. This update should be performed according to the instructions in TSB 2011732: 00 Software Version Management (SVM), operating instructions.

Before proceeding with the update, technicians must verify the current software version of the Data Bus On Board Diagnostic Interface -J533- (0019). If the current version is 0025, the TSB instructions should be followed. The update is carried out via SVM using the "Flash" mode on the ODIS tester, utilizing the SVM – Authorized Multiple Code Entry function.

For vehicles equipped with high-voltage components, it is critical to unplug the high-voltage charging cable before entering the SVM code. This prevents potential damage to the high-voltage battery during the software update process. The specific SVM code required for this update is ZGDOIP,19A025.

After the software update is complete, the diagnostic connector and any charging cables must be unplugged from the vehicle. The engine should then be started and allowed to run for one minute, followed by locking the vehicle and waiting for five minutes. These steps ensure the system properly integrates the new software before the diagnostic procedure is finalized and event memory entries are cleared.
