2025-2026 Audi MMI Tire Pressure 'Storing Values' TSB

Audi has released Technical Service Bulletin (TSB) 2079417/2, titled "44 Tire pressure cannot be stored," to address a specific concern affecting certain 2025-2026 Audi models. This bulletin, with Transaction No. 2079417/2 and released on January 23, 2026, details a situation where the Multi Media Interface (MMI) display may get stuck during the tire pressure storage process, specifically showing the message "Storing values" indefinitely. This issue can prevent the correct display of tire pressures.

This problem primarily impacts a range of 2025-2026 Audi vehicles, including the A5, S5 (FU), Q5, Q5 Sportback, SQ5, SQ5 Sportback (GU), A6 Sportback e-tron, S6 Sportback e-tron, Q6 e-tron, Q6 Sportback e-tron, SQ6 e-tron, SQ6 Sportback e-tron, and A6 (FN) models. It specifically affects vehicles equipped with the direct measuring tire pressure monitoring system, identified by PR number 7K3.

Revision History

This Technical Service Bulletin has undergone revisions to ensure comprehensive coverage and accuracy:

• Revision 2 (January 23, 2026): The header was revised to include additional models, and the condition section was updated with a more detailed model table.
• Revision 1 (September 25, 2025): This was the initial publication of the bulletin.

Symptoms

Owners of affected Audi vehicles may observe the following symptoms related to the tire pressure monitoring system:

• The MMI display shows the message "Storing values" and remains stuck at this stage when attempting to save tire pressures.
• The verbatim message "tire pressures are not displayed on the MMI" may appear, even after initiating the storage process.
• The system may indicate "Connection offline" or the general fault "44 Tire pressure cannot be stored" in diagnostic scans, though these are not typically user-facing messages. This condition indicates that the MMI display is not correctly processing the information from the tire pressure monitoring system, leading to the visual hang-up and the inability to store tire pressure values.

Technical Background and Diagnosis

The underlying cause of this issue is that the display on the MMI is not being processed correctly. When a customer attempts to store tire pressures, the system initiates the process, but the MMI fails to update beyond the "Storing values" stage. This complaint can often be reproduced by technicians and may have even been noted during pre-delivery inspections of new vehicles.

Repair Procedure Summary

Audi TSB 2079417/2 outlines a two-step approach to resolve the "Audi tire pressure cannot be stored" problem, focusing on proper initialization and, if necessary, further diagnostics:

1. Initial Attempt for Display Stuck on "Storing values": If the MMI display is stuck at the "Storing values" stage, the first recommended step is to press the "Back" button on the MMI. It is important to note that even if the display does not immediately change, the initialization of the tire pressure monitoring system has been triggered. Following this, perform a test drive of approximately 10 minutes at a speed greater than 30 mph. This driving period allows the system to complete its initialization and correctly display the tire pressures on the MMI.
2. Further Diagnostics (If Issue Persists): If the display still does not function correctly and the tire pressures are not displayed on the MMI after the initial steps and test drive, further investigation is required. Technicians should then check the tire pressure monitoring system, specifically addressing module (address 0065), and the sensors located within the tires. This diagnostic process requires the use of a specialized diagnostic tool.

Required Tools or Parts

For the second stage of diagnosis, if the initial steps do not resolve the issue, technicians will need to use the following diagnostic equipment:

• VAS 741099: This is a specific diagnostic tool used to check the tire pressure monitoring system (address 0065) and its associated sensors.

Important Warnings

Audi explicitly states that "Billing to this TSB number is not permitted." This indicates that the service information provided is purely a guideline for resolving the issue and should not be used as a direct basis for warranty claims or billing. Technicians should consult the Repair Manual for any fasteners, bolts, nuts, and screws that require replacement during the repair, as well as their Parts Department and ETKA for the latest information and parts bulletins.

Owner Action

If you experience your 2025-2026 Audi's MMI display getting stuck on "Storing values" when trying to save tire pressures, you can first try the recommended owner action: press the "Back" button on your MMI and then perform a test drive for about 10 minutes at over 30 mph. This often resolves the "Audi tire pressure cannot be stored" issue. If the problem persists and the tire pressures are still not displayed on the MMI, it is recommended to contact your authorized Audi service center. They have access to the full TSB 2079417/2 and the necessary diagnostic tools, such as VAS 741099, to properly diagnose and resolve the underlying problem with your tire pressure monitoring system.
