2025 Audi MMI System Time Change Issue (PSS 2077132/3)

Audi has issued Pending Service Solution (PSS) 2077132/3 to address a software-related concern affecting the Multi Media Interface (MMI) system in several 2025 Audi models. This PSS outlines an issue where the MMI system fails to automatically adjust the time for daylight saving changes. This document provides guidance to dealerships and informs owners about the nature of the problem and the anticipated resolution.

The Audi A5 MMI time change issue is a known software glitch that impacts the convenience and accuracy of the vehicle's integrated time display. Audi is actively working on a permanent software update to correct this behavior.

Symptoms Owners May Notice

Owners of affected 2025 Audi vehicles may observe that their MMI system does not automatically change to daylight saving time or back. This occurs even when the automatic time adjustment setting has been enabled within the MMI system. The incorrect time display is consistent across all vehicle displays that show the time, not just the primary MMI screen.

This behavior, while inconvenient, is temporary. The system typically rectifies itself after one or more bus sleep cycles, which occur when the vehicle's electrical system powers down after being turned off for a period.

Technical Background

The root cause of the MMI system's inability to automatically adjust for daylight saving time is a software issue. Modern vehicle systems rely heavily on complex software, and occasional glitches can arise that affect various functions, including timekeeping. Audi's technical teams have identified this specific software anomaly.

Important Warnings for Owners

Audi explicitly states that owners should not replace any components for this condition since this will not resolve the customer's concern. This is a critical advisory, as replacing hardware will not fix a software-based problem and could lead to unnecessary expenses or diagnostic time. Furthermore, this specific TSB is informational only and is not applicable to any Audi Warranty, meaning any diagnostic or repair work performed outside of the official software update might not be covered.

What Audi is Doing

Production Solution

Audi has implemented a production solution to prevent this issue in newly manufactured vehicles. This concern will no longer occur in vehicles manufactured from week 48 of 2025 or later. This indicates that the software fix is being integrated into the production line for upcoming vehicles.

Service Instructions for Dealers

Dealerships are instructed to explain to customers that a definitive solution, in the form of optimized software, is expected to be available by the end of the fourth quarter of 2025. This timeline is subject to change. At this point, no repairs are deemed necessary by Audi. Dealers are also required to create a PSS record in the Pending Service Solutions application via AccessAudi. This record-keeping helps Audi track the prevalence of the issue and ensures that affected vehicles can be easily identified for the eventual software update.

Temporary Workarounds

While waiting for the permanent software solution, owners experiencing the Audi A5 MMI time change issue have a few temporary workarounds:

• Self-Resolution: The issue may resolve itself after a few minutes, particularly after the vehicle has undergone a bus sleep cycle. A bus sleep cycle occurs when the vehicle's electronic control units power down after the ignition is turned off, effectively resetting certain systems.
• Soft Reset: Performing a soft reset of the MMI system can also remedy the problem. This is typically done by pressing and holding the volume control knob for several seconds until the MMI system reboots. This action can often clear minor software glitches without affecting settings or data.

Revision History

This PSS 2077132/3 has undergone several revisions since its initial publication, reflecting ongoing updates and clarifications from Audi:

• Revision 3: This revision included a revised service instruction with an updated estimated time of arrival (ETA) for the permanent solution.
• Revision 2 (June 23, 2025): This update revised the header to add additional models to the scope and included a notice regarding launch vehicles in the service instructions.
• Revision 1 (March 07, 2025): This was the initial publication of the Pending Service Solution.

What Owners Should Do

If you own a 2025 Audi A5, Q5, or other affected PPE/PPC model and experience the Audi A5 MMI time change issue, you should be aware that this is a known software problem. There is no need for immediate repair or component replacement. You can try the temporary workarounds, such as a soft reset of the MMI system or allowing the vehicle to complete a bus sleep cycle. Audi anticipates a permanent software update by the end of Q4 2025. You may wish to contact your authorized Audi dealership for the latest information regarding the availability of this update and to ensure a PSS record is created for your vehicle.
