2025-2026 Audi Service Interval Display Issue TSB 2081327

Audi has issued Technical Service Bulletin (TSB) 2081327, titled "90 PSS Deviation in calculation of service interval for inspection," to inform technicians and owners about a potential software-related problem affecting the service interval display in certain 2025-2026 models. This bulletin, released on March 13, 2026, highlights an issue where the vehicle's system may not accurately reflect when an inspection is due.

Symptoms of the Audi Service Interval Display Issue

Owners of affected vehicles may notice that their "service interval display may indicate too late that an inspection is due." In the most critical scenarios, this inaccuracy could mean that the vehicle exceeds the recommended "maximum distance and/or maximum time between two inspection intervals." This could lead to delayed maintenance, potentially impacting vehicle longevity or warranty coverage if not addressed promptly by following the manufacturer's service schedule.

Technical Background

The root cause of this inaccurate Audi service interval display is identified as a "Software issue in HCP3." HCP3 refers to a specific software platform or control unit within the vehicle's electrical system responsible for managing various functions, including service reminders.

Important Warnings for Owners

Audi explicitly states that owners and technicians should "Do not replace any components for this condition since this will not resolve the customer's concern." This emphasizes that the issue is software-based, and hardware replacement is unnecessary and ineffective. Furthermore, this TSB is informational only and "not applicable to any Audi Warranty," meaning any diagnostic or logging procedures related to this specific TSB are not covered under standard warranty terms.

Manufacturer's Plan and Pending Solution

Audi acknowledges that a definitive solution for this software issue is "currently under development." The manufacturer anticipates that a fix will be available by the end of the second quarter of 2026, though this timeline is subject to change. Until then, the primary action for dealers is to explain the situation to customers and create a record in the Pending Service Solutions (PSS) application.

What Owners Should Do

If you own an affected 2025-2026 Audi model and suspect an issue with your Audi service interval display, it is crucial to continue performing inspections according to your vehicle's standard Service Schedule. While a software fix is pending, your dealership can create a PSS record through the "Pending Service Solutions (PSS)" link in Audi Now, under the path "Service | AU-US > Pending Service Solutions (PSS)." This ensures that your concern is documented and you will be notified once the software solution becomes available.
