2023-2025 Audi S3, A3, A5, Q5, Q7, Q8 Analysis List

Audi has issued an "On-car analysis list" dated December 8, 2025, which provides detailed guidance for technicians on how to investigate specific concerns across various models, including the 2025 Audi S3. This document is crucial for accurate diagnosis and reporting. It also refers to TSB 2066297 for information on the '00 VIN-4-PIN reporting program (V4P, vin4pin).

Important Warnings

Audi explicitly states, "Please contact Audi Helpline before attempting repair." This emphasizes the need for professional assistance and adherence to manufacturer guidelines. Owners should not attempt to diagnose or repair these issues themselves without consulting an authorized Audi service center.

Symptoms and Fault Codes

This analysis list covers three primary topics, each with specific symptoms and diagnostic considerations:

• 48V Battery Cooling Fan: Owners may experience issues related to the 48V battery cooling fan, often indicated by the diagnostic trouble code "P0A8200". This code suggests a problem within the 48V battery system's cooling circuit.
• B&O Extendable Tweeter: For vehicles equipped with the Bang & Olufsen audio system featuring extendable/retractable tweeters in the dash, the primary symptom is the "tweeter gets stuck or shutters during operation." This can affect audio quality and the aesthetic function of the system.
• PPE - PPC Vehicles Time Off by 1 Hour: Certain PPE (Premium Platform Electric) and PPC (Premium Platform Combustion) vehicles may display incorrect time, specifically showing "time is off by 1 hour." This issue can manifest in the instrument cluster and MMI system.

Diagnosis and Information Gathering

For each identified issue, Audi provides specific steps for technicians to gather comprehensive diagnostic information:

48V Battery Cooling Fan (DTC P0A8200)

When diagnosing a "P0A8200" fault, technicians are instructed to upload a diagnostic LOG to the paperless system. This log should show the DTC in DA0021. Additionally, pictures taken during work instructions, as provided by the Technical Assistance Center (TAC), are required to document the issue thoroughly.

B&O Extendable Tweeter Malfunction

To diagnose the "tweeter gets stuck or shutters during operation" problem, technicians must:

1. Record a short video clearly duplicating the concern.
2. Manually extend the tweeter fully, then cycle the key to see if the function is restored.
3. Verify if output diagnosis works correctly.
4. Clear any existing faults and re-evaluate the system.

PPE - PPC Vehicles Time Off by 1 Hour

For vehicles displaying "time is off by 1 hour" in the cluster or MMI, technicians should create a WEB TAC case with all documentation. Required information includes:

• A single photo showing the time in the cluster, time settings in the MMI, and the navigation location and time from another phone.
• Reading all Measured Value Blocks (MVB's) from Da0075 when the issue is NOT present.
• Reading all MVB's from Da0075 when the issue is actively occurring, documenting the log ID to correspond.
• Specific location information (address or GPS location) where and how the duplicate occurs.
• Confirmation if the issue can be duplicated on other vehicles.
• Information on whether the area of concern is close to another time zone.

This detailed data collection helps Audi engineers understand the root cause and develop effective solutions for these issues, including the 2025 Audi S3 manufacturer_communication topics.

Owner Action

If you own a 2023-2025 Audi model and are experiencing any of the symptoms described, such as a "P0A8200" code, a malfunctioning B&O tweeter, or incorrect vehicle time, it is recommended to contact your authorized Audi dealership. Reference the Audi On-car analysis list from December 8, 2025, and TSB 2066297 for the VIN-4-PIN reporting program. Your dealer will have access to the latest diagnostic procedures and can perform the necessary information gathering and repairs.
