2025 Audi MMI Time Change Issue (TSB 2077132/2)

Audi has issued a Pending Service Solution (PSS) identified as TSB 2077132/2 to address a software-related concern affecting the Multi Media Interface (MMI) system in certain 2025 models. This technical bulletin specifically details instances where the MMI system fails to automatically adjust the time for daylight saving, even when the automatic time adjustment feature is enabled. This issue impacts the accuracy of the time displayed across all vehicle screens and can be a source of frustration for owners.

Symptoms

Owners of affected vehicles will observe that the time displayed in their MMI system does not automatically change to daylight saving time or revert to standard time. This occurs despite the automatic time adjustment setting being active within the MMI. The incorrect time is consistently shown across all displays that rely on the MMI's clock.

Diagnosis / Trigger Conditions

This Audi MMI time change issue is readily reproducible in a workshop setting, confirming its consistent nature. The problem stems from a software anomaly rather than a hardware malfunction, leading to the system's inability to correctly process and apply time zone changes.

Important Warnings for Owners

Owners should be aware of several key points regarding this issue:

• Do not replace any components: Audi explicitly states, "Do not replace any components for this condition since this will not resolve the customer's concern." This is crucial advice, as the problem is software-based, and replacing MMI hardware will not fix the underlying bug.
• No immediate repair necessary: Audi's communication indicates that "no repairs are necessary at this point." Owners are advised that a permanent software solution is currently under development and is expected to be available by the end of the 3rd quarter of 2025. This timeline is subject to change.
• Informational only: This TSB is for informational purposes for dealers and is not applicable to any Audi Warranty claims in the traditional sense, as it's a known software bug with a future fix.

Workarounds

While a permanent software update is pending, owners experiencing the Audi MMI time change issue can use temporary workarounds:

• Soft Reset: The issue may resolve itself after a few minutes. Alternatively, performing a soft reset of the MMI system can often rectify the problem. This is typically done by pressing and holding the volume control knob until the system restarts.
• Bus Sleep Cycle: Allowing the vehicle to complete one or more bus sleep cycles (i.e., turning the vehicle off and letting it sit for a period) can also resolve the incorrect time display.

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 in week 48 of 2025 or later. This means that vehicles produced after this date should not exhibit the automatic time adjustment problem.

Repair Procedure Summary for Dealers

For vehicles still within the new model launch repair authorization period, workshops are instructed to:

1. Create a PSS Record: Technicians must create a record in the Pending Service Solutions (PSS) application via the PSS link in AccessAudi (under Related Links >> Service).
2. TAC Case Reference: For vehicles in the launch phase, a case must be created with the Technical Assistance Center (TAC) per the repair authorization. The TSB 2077132/2 number should be referenced in the first line of the TAC case.
3. Customer Communication: Explain to the customer that a solution is anticipated by the end of Q3 2025 and that no repairs are needed currently.
