2022-2023 Audi A3, S3, RS 3 Incorrect Date Display TSB

Owners of 2022-2023 Audi A3, S3, and RS 3 vehicles equipped with Virtual Cockpit Gen2+ may encounter a frustrating issue where an Audi S3 incorrect date display appears on both the instrument cluster and the MMI screen. This TSB, identified as 91 23 85 2067330/3, provides the necessary steps for technicians to resolve this problem.

This bulletin, dated March 31, 2023, supersedes an earlier version, TSB 23-66, which was issued on January 31, 2023. The update includes revised instructions and an added SVM flash table to ensure accurate repairs.

Symptoms

If your 2022-2023 Audi A3, S3, or RS 3 is affected, you will observe the following:

• "An incorrect date is displayed on the instrument cluster and MMI screen."
• "The date displayed is far in the future (≥ year 2040)."
• "It is not possible to manually correct the date via the MMI."

This persistent Audi S3 incorrect date display can be a nuisance for drivers relying on accurate time and date information within their vehicle's systems.

Technical Background

The root cause of the incorrect date display has been identified as a hardware issue within the emergency call module J949. This module's malfunction can lead to the system incorrectly reporting the date, causing the futuristic display on the instrument cluster and MMI.

Audi has implemented an optimized software solution for the instrument cluster in production vehicles to prevent this issue from occurring in new units.

Important Warnings

When performing diagnostic or repair procedures related to this TSB, technicians are advised to: "Always use DoIP when flashing a control module via ODIS in supported vehicles."

Repair Procedure Summary

Resolving the Audi S3 incorrect date display involves a multi-step process performed by a qualified Audi technician. The procedure outlined in TSB 91 23 85 2067330/3 includes:
