2022 Audi A4, A5, Q5 Lane Departure Warning Steering Input TSB

Owners of certain 2022 Audi A4, A5, and Q5 models may encounter a specific problem with their vehicle's lane departure warning system. Technical Service Bulletin (TSB) 2079617/1, released by Audi on October 7, 2025, addresses a condition where the "Steering input" setting for this assistance feature is not available within the Multi Media Interface (MMI).

This TSB is crucial for understanding and resolving the Audi lane departure steering input issue, ensuring that drivers can fully customize their vehicle's safety and assistance features. The problem has been confirmed to be reproducible by workshop technicians, indicating a consistent software-related fault.

Symptoms

The primary symptom reported by customers is the unavailability of the "Steering input" setting for the lane departure warning system in the MMI. This affects various lane assist warning point settings, including both "lane assist late warning point setting" and "lane assist early warning point setting," rendering them non-adjustable. The system's functionality is present, but the specific customization option for steering input is missing, leading to a complaint type of "functionality -> not adjustable."

From a workshop perspective, the object of complaint is categorized under "information, navigation, communication, entertainment -> operation, control, speech input -> information electronics control module," with the complaint type being "control modules, services -> software faulty." This clearly points to a software-related malfunction within the vehicle's central electronics.

Technical Background

Audi has identified the root cause of the Audi lane departure steering input problem as a software issue within the vehicle's information electronics control module. This fault prevents the MMI from displaying or allowing adjustments to the "Steering input" setting, which is part of the broader assistance systems and comfort controls. The TSB explicitly states the technical background as a "Software issue."

PR Numbers

The TSB also references specific PR numbers related to the vehicle's configuration. For this particular issue, the relevant PR number is identified as "?:with 611."
