2022 Audi e-tron GT Rear Seat Belt Warning TSB

Symptoms

Owners of 2022 Audi e-tron GT and RS e-tron GT vehicles may notice a persistent red indicator light in the Audi virtual cockpit. This light, which is part of the rear safety belt monitoring system, remains illuminated even after rear passengers have exited the vehicle and the seats are no longer occupied. In some instances, a warning tone may also sound while driving, accompanying the visual warning.

Diagnosis / Trigger Conditions

Audi Technical Service Bulletin PSS 90 (90 21 20 2064854/1) details a specific sequence of events that can lead to this persistent 2022 Audi e-tron GT rear seat belt warning. The issue typically arises after the following scenario:

1. The driver and rear passengers are wearing their safety belts while the vehicle is in motion, with no initial warnings present.
2. The driver stops the vehicle and turns off the engine and ignition.
3. Rear passengers then unfasten their safety belts.
4. The driver exits the vehicle and opens a rear door for passengers (e.g., a child) to alight. It's also possible that rear passengers' safety belts were fastened until this point and are now unfastened by the driver.
5. The rear door is closed, and the rear seats are confirmed to be unoccupied.
6. The driver re-enters the vehicle, closes their door, and fastens their safety belt.
7. The driver switches the vehicle back on or only switches the ignition on to continue their journey.

At this stage, the red indicator light for the rear safety belt monitoring system illuminates in the Audi virtual cockpit. The visual and acoustic warnings can only be cleared by cycling the ignition off and on again, or by opening the driver's door while the vehicle is stationary. The issue does not occur if, after rear door activity, the vehicle is immediately locked and enters sleep mode without being driven again.

Important Warnings

Audi explicitly states in Technical Service Bulletin PSS 90 (2064854/1) that no components should be replaced for this condition since this will not resolve the customer's concern. This warning is crucial for owners, as it prevents unnecessary repairs or part replacements for a problem that is software-related.

Repair Procedure Summary

As of the release of Technical Service Bulletin PSS 90 on November 3, 2021, a permanent solution for the persistent 2022 Audi e-tron GT rear seat belt warning is anticipated in the first quarter of 2022. Until this software fix is available, Audi advises technicians not to replace any components for this specific condition. Instead, dealers are instructed to create a PSS (Pending Service Solutions) record. This record can be created through the PSS application found via the Pending Service Solutions link in AccessAudi (under Related Links >> Service) or through the Technical Assistance page in Elsa. This process helps Audi track the prevalence of the issue and ensures that affected vehicles are documented while awaiting the official software update.

Owner Action

If you own a 2022 Audi e-tron GT or RS e-tron GT and are experiencing the persistent rear seat belt warning light, it's important to understand that this is a known software issue. There are currently no diagnostic trouble codes (DTCs) associated with this specific problem, and no physical components need replacement. You can temporarily clear the warning by turning the ignition off and on again, or by opening the driver's door while the vehicle is stationary. Audi anticipates a software solution will be available in the first quarter of 2022. It is recommended to discuss this Technical Service Bulletin PSS 90 (2064854/1) with your Audi dealership at your next service appointment to ensure your vehicle receives the forthcoming software update.
