2023-2025 Audi On-Car Analysis List for Technicians

Audi has issued an on-car analysis list, TSB 2066297, to assist technicians in diagnosing and reporting specific issues observed in certain 2023-2025 Audi vehicles. This document serves as a guide for gathering comprehensive information when encountering particular faults, including the Audi P0A8200 diagnostic trouble code related to the 48V battery cooling fan.

This technical bulletin aims to streamline the diagnostic process and ensure that sufficient data is collected for further analysis by Audi's technical support. It covers three distinct areas of concern that require detailed reporting from service personnel.

Important Instructions for Service Personnel

Audi emphasizes specific protocols for technicians before attempting any repairs related to the issues outlined in this document:

• "Please contact Audi Helpline before attempting repair"
• "Please see TSB 2066297 '00 VIN-4-PIN reporting program (V4P, vin4pin) for more info about the program"

These instructions highlight the importance of proper reporting and consultation with Audi's technical support channels to ensure accurate diagnosis and resolution.

Overview of On-Car Analysis Topics

The TSB 2066297 details three primary topics for on-car analysis, each with specific reporting requirements:

48V Battery Cooling Fan (DTC P0A8200)

This section addresses issues related to the 48V battery cooling fan, specifically when the Diagnostic Trouble Code (DTC) "P0A8200" is present. Technicians are instructed to upload diagnostic logs to a paperless system, showing the DTC "P0A8200" in DA0021. Additionally, pictures must be provided during work instructions as specified by the Technical Assistance Center (TAC). Owners experiencing issues potentially related to the 48V battery system, especially if a check engine light or warning message appears, should be aware of the Audi P0A8200 code.

B&O Extendable Tweeter Malfunction

For Audi vehicles equipped with the B&O audio system featuring extendable/retractable tweeters in the dash, this topic covers instances where the "Tweeter gets stuck or shutters during operation." Technicians are required to:

• Take a short video demonstrating the concern.
• Fully extend the tweeter manually and cycle the key to see if function is restored.
• Verify if output diagnosis works correctly.
• Clear any faults and re-evaluate the system.

PPE/PPC Vehicle Time Discrepancy

This section addresses a specific issue where the time displayed in PPE (Premium Platform Electric) and PPC (Premium Platform Combustion) vehicles is "off by 1 hour." Comprehensive documentation is required for this issue, including:

• A photo showing the time in the instrument cluster, time settings in the MMI, and another phone displaying the navigation location and time, all in one image.
• 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.
• Providing specific location information, including whether the issue can be duplicated on other vehicles, if the area of concern is close to another time zone, and an address or GPS location where the concern happens.

What This Means for Owners

While this document is primarily for technicians, owners of 2023-2025 Audi A3, A5, A6, A7, A8, Q5, Q7, Q8, and related S/RS models should be aware of these potential issues. If you experience a malfunction with your B&O extendable tweeter, notice your vehicle's clock is consistently off by an hour, or if a warning light indicates a problem with the 48V battery system, potentially signaling an Audi P0A8200 fault, your service technician will follow these detailed reporting guidelines. Providing clear descriptions and, if possible, videos of the symptoms can assist your technician in gathering the necessary information for Audi's helpline.
