2022 Audi Intersection Assist Directional Arrows Flicker TSB

Owners of certain 2022 Audi models equipped with front cross traffic assist may notice an issue where the directional arrows of the intersection assist system flicker. This behavior, described in Audi Technical Service Bulletin 96 24 97 2073987/1, specifically occurs under certain conditions after the vehicle has been started.

Symptoms

If you own a 2022 Audi A6, A7, A8, Q7, Q8, or e-tron model, you might observe the Audi intersection assist flicker. This symptom manifests when the vehicle is turned on after waking up from a 'bus sleep' state. When the rear view or top view camera is then manually selected via the button in the center console, the directional arrows displayed by the intersection assist system may flicker. This flickering typically continues until the vehicle begins to move. The display may also show the message "Fahrweg kontrollieren!", which translates to "Control trajectory!" or "Check path!".

Fault Codes / DTCs

Audi's workshop findings indicate that no relevant DTCs (Diagnostic Trouble Codes) are stored in the vehicle's system when this flickering occurs. This means the issue does not trigger a standard fault code that technicians would typically diagnose.

Diagnosis / Trigger Conditions

The Audi intersection assist flicker is consistently reproducible under specific conditions. It occurs after the vehicle has been in a 'bus sleep' state, which is a low-power mode the vehicle enters when turned off for a period. Upon restarting the vehicle and manually activating the rear view or top view camera, the flickering begins. It's important to note that this issue does not occur if the rear view or top view camera is activated by simply putting the vehicle into reverse.

Repair Procedure Summary

Audi has identified the root cause of this flickering as a software-related issue within the driver assist systems control unit, specifically the -J1121- control unit. To resolve this, an optimized software version, SW0381, has been implemented in production vehicles. For affected vehicles already on the road, the repair involves performing a software update. This service action is detailed in TSB 2069244. Owners experiencing the Audi intersection assist flicker should contact their authorized Audi dealership to schedule this software update.

Important Warnings

Owners should be aware that the flickering of the intersection assist arrows is specifically tied to manually selecting the rear view or top view camera after the vehicle wakes from a bus sleep state. This issue does not occur when the rear view / top view camera is activated by putting the vehicle into reverse.

Owner Action

If you are experiencing the Audi intersection assist flicker in your 2022 Audi model, you should contact your local authorized Audi dealership. Inform them about the symptoms and reference Technical Service Bulletin 2073987/1 or 2069244. The dealership will be able to diagnose the issue and perform the necessary software update to the driver assist systems control unit -J1121-.
