2024 Audi Q8/SQ8 Headlight Software Update 94CB

Symptoms

Owners of certain 2024 Audi Q8 and SQ8 vehicles may experience an "erroneous fault message" appearing in the instrument cluster. This message indicates a problem within the vehicle's headlight system, specifically stemming from a software issue. While the exact wording of the message isn't specified beyond being an "erroneous fault message", it points to a malfunction related to the headlights.

Diagnosis / Trigger Conditions

The root cause of the "erroneous fault message" is identified as a software issue residing within the control unit responsible for the headlights. This software anomaly leads to the incorrect display of a fault message in the instrument cluster, even if there is no physical defect with the headlights themselves. The issue is purely software-based, affecting how the control unit communicates its status.

Repair Procedure Summary

Audi has issued Technical Service Bulletin UPDATE 94CB to address this software-related headlight fault. The repair involves updating the software for the light control module. This update is available as of April 17, 2024. Dealers are instructed to consult ELSA and Service References in Elsa2Go for comprehensive repair and claiming instructions. The process includes checking daily campaign open inventory reports to identify affected vehicles and ensuring all vehicles in inventory receive the update before customer delivery.

Important Warnings and What Owners Should Know

Audi emphasizes several critical points regarding this UPDATE 94CB:

• No Owner Notification: Unlike recalls and service actions, consumers will not be receiving letters about this software update. Owners must proactively seek this information or have the update performed during a service visit.
• Dealer Inventory Embargo: Affected vehicles currently in dealer inventory cannot be delivered to consumers until this software Update is completed. This ensures that new vehicles are delivered with the latest software.
• Pre-Delivery Update: Dealers are required to ensure that every affected vehicle receives the update before delivery to consumers. This is part of Audi's commitment to quality expectations.
• Service Visit Update: Any vehicle brought into an authorized Audi workshop for maintenance or other service that shows this Update code open in ELSA on the day of repair will have the work completed.

Owner Action

If you own a 2024 Audi Q8 or SQ8 and have observed an "erroneous fault message" in your instrument cluster related to the headlights, or if you simply want to ensure your vehicle has the latest software, you should contact your authorized Audi dealership. They can check if your vehicle is affected by this software issue and perform the necessary update to the light control module under TSB UPDATE 94CB. Since owners will not be notified, it is important to be proactive.
