2021-2022 Audi MMI Lane Assist Steering Correction Issue

Audi has released Technical Service Bulletin (TSB) PSS 91 2066074/1 to address a specific software malfunction affecting the MMI system in certain 2021-2022 models. This bulletin highlights an issue where the Audi lane assist steering correction setting cannot be accessed by the driver.

The TSB, dated February 10, 2022, informs technicians and owners that a fix is under development. It provides crucial guidance on how to handle customer inquiries regarding this particular problem.

Symptoms

Owners of affected Audi vehicles may notice that the setting for the lane assist steering correction is simply missing or inaccessible within the Multi Media Interface (MMI) system. The primary symptom reported by customers is: "The steering correction setting for the lane assist is not available in the MMI."

This means drivers are unable to adjust or enable the steering correction feature of their lane assist system, which is intended to help keep the vehicle centered in its lane. The functionality is simply absent from the MMI options.

Fault Codes / DTCs

Importantly, Audi's workshop findings indicate that for this specific condition, "No relevant DTCs are stored." This means that technicians will not find any diagnostic trouble codes (DTCs) in the vehicle's system that directly point to this software malfunction. The absence of DTCs can make initial diagnosis challenging without knowledge of this TSB.

Technical Background

The underlying cause of the missing Audi lane assist steering correction setting is identified as a software malfunction within the MMI system. This software glitch prevents the setting from being displayed or made available to the user, even though the lane assist hardware may be functioning correctly otherwise.

Audi has acknowledged this software issue and is actively working on a permanent resolution. The TSB serves as an interim communication to guide dealerships while the solution is being developed.

Important Warnings for Owners

Audi has provided specific instructions to dealerships that are vital for owners to understand:

• Do not replace components: The TSB explicitly states: "Do not replace any components for this condition since this will not resolve the customer's concern." This means that replacing parts like the MMI unit or other related modules will not fix the software malfunction and would be an unnecessary expense.
• Solution forthcoming: Customers should be informed that "a solution is forthcoming by the end of the 1st quarter of 2023." This provides a timeline for when a software update or other remedy might become available.
• Not a warranty repair (yet): The TSB is currently designated as "informational only and not applicable to any Audi Warranty." This indicates that the current bulletin does not authorize warranty claims for a repair, as the actual fix is still in development.

Repair Procedure Summary

As of the release of TSB PSS 91 2066074/1, a definitive repair procedure is still under development. Audi states that "This bulletin will be updated when more information is available. A solution is currently under development." In the meantime, technicians are instructed to explain the situation to customers and to create a Pending Service Solutions (PSS) record within Audi's internal systems. This helps Audi track the prevalence of the issue and manage the upcoming solution.

Owner Action

If you own a 2021-2022 Audi vehicle and are experiencing the Audi lane assist steering correction setting being unavailable in your MMI, you should contact your authorized Audi dealership. Inform them of the issue and reference Technical Service Bulletin PSS 91 2066074/1. Your dealer can confirm the status of the upcoming solution and create a PSS record for your vehicle.

It is important to remember that, per Audi's instructions, no components should be replaced for this condition, as it is a software issue that will not be resolved by hardware replacement. A software update is expected to be released by the end of the first quarter of 2023 to address this malfunction.
