2019-2022 Audi Lineup Adaptive Light / Driver Assist Malfunction TSB

Audi has released Technical Service Bulletin (TSB) PSS 90, reference number 90 22 55 2060332/6, to address issues with adaptive light and driver assistance systems in various 2019-2022 Audi models. This TSB supersedes an earlier bulletin, Group 90 number 22-35, dated January 14, 2022.

Symptoms

Owners of affected Audi vehicles may experience several issues related to their driver assistance systems. These symptoms often appear intermittently and resolve themselves after a short period.

Common reports include:

• "The driver assistance systems are inoperable."
• "A warning message is displayed in the instrument cluster."
• "Audi adaptive light malfunction"
• "Audi pre sense system error"
• "Adaptive vehicle assistance restricted"
• "Adaptive vehicle assistance predictive regulation currently restricted"
• After a few seconds, the driver assistance systems become available again.

Fault Codes / DTCs

When these symptoms occur, technicians performing diagnostics may find the following Diagnostic Trouble Code (DTC) stored intermittently in the J1121 control module for driver assist systems (address word 00A5):

Code	Description	Symptom Code	Condition
C12D5FA	Control unit for driver assist systems, picture processor does not respond	221281	Sporadic

This DTC indicates a communication issue where the picture processor within the driver assist control unit is not responding as expected.

Diagnosis / Trigger Conditions

The technical background provided by Audi indicates that the diagnostic function itself is too sensitive. This means the system is triggering an error message and DTC C12D5FA even when there isn't a persistent hardware failure.

Important Warnings

Audi explicitly states that no components should be replaced for this condition. Replacing parts will not resolve the underlying issue, as the problem stems from the diagnostic sensitivity, not a faulty component. A permanent solution is currently under development by Audi, with an expected release in the first quarter of 2023.

Repair Procedure Summary

For vehicles presenting with an "Audi e-tron adaptive light malfunction" or other related driver assist system errors and DTC C12D5FA, the current service procedure is as follows:

1. Delete the stored DTC C12D5FA from the vehicle's system.
2. Inform the customer that a permanent solution is anticipated in the first quarter of 2023. Emphasize that no repairs or component replacements are necessary at this time.
3. Create a PSS (Pending Service Solutions) record in the PSS application via AccessAudi or the Technical Assistance page in Elsa. This helps Audi track the prevalence of the issue while a long-term fix is being developed.

Warranty Information

Warranty claims for this issue fall under specific claim types:

• 110: Applicable for vehicles up to 48 months or 50,000 miles.
• G10: For CPO (Certified Pre-Owned) Covered Vehicles, requiring verification of owner status.

If the vehicle is outside of warranty, this TSB serves as informational guidance only. The service number is 9093, and the damage code is 0039. Diagnostic time (GFF) is based on the diagnostic protocol, with no allowance for road tests before or after the service procedure.

Owner Action

If you experience an "Audi e-tron adaptive light malfunction" or any of the other listed driver assistance system warnings, it is recommended to visit an authorized Audi dealership. The dealership will perform the diagnostic check, delete the DTC C12D5FA, and inform you about the ongoing development of a permanent solution. It is crucial to remember that no parts replacement is needed for this specific condition, as per Audi's guidance.
