2022-2024 Audi Q5 EPC Light P060C00 U041600 TSB

Audi has released Technical Service Bulletin (TSB) 2076356/2 to address specific engine control unit drive system faults in 2022-2024 Audi Q5 vehicles. This bulletin, released on April 3, 2025, provides a solution for owners experiencing an illuminated EPC light and related drive system fault messages. The issue is linked to diagnostic trouble codes P060C00 and U041600, which point to a software problem within the engine control module.

Symptoms

Owners of affected 2022-2024 Audi Q5 models may observe the following symptoms:

• The "EPC light is on" in the instrument cluster.
• A "Drive system fault appears in the instrument cluster" message.

These indicators suggest a potential issue with the engine's electronic control systems, prompting the need for diagnosis and repair as outlined in TSB 2076356/2.

Fault Codes / DTCs

When diagnosing the issue, technicians may find the following event memory entries logged in the engine control unit:

• P060C00: "Internal Control Module Main Processor Performance with DFCC 44160"
• U041600: "Invalid Data Received from Vehicle Dynamics Control Module with DFCC 34193"

These specific diagnostic trouble codes confirm the presence of the software-related fault that TSB 2076356/2 aims to correct. If your Audi Q5 EPC light P060C00 is illuminated, these DTCs are likely present.

Technical Background

Audi has identified the root cause of these symptoms and fault codes as a software issue within the engine control unit, specifically the -J623- module (address word 0001). This software anomaly can lead to incorrect readings or performance issues, triggering the EPC light and drive system fault messages.

Repair Procedure Summary

To resolve the engine control unit drive system faults, Audi's TSB 2076356/2 outlines a software update procedure for the affected vehicles. This update specifically targets the engine control module to correct the underlying software condition.

The repair involves the following general steps:

1. Preparation: Technicians must follow all instructions detailed in TSB 2011732, which covers Software Version Management (SVM) operating procedures.
2. Software Update: The -J623- engine control unit (address 0001) is updated using a specific SVM action code, 01A267. This update replaces older software versions with newer, corrected versions. For example, old software part number 80A.907.115.B (version 0001) is updated to version 0003, while 80A.907.115.C (version 0001) is updated to version 0002, and 80A.907.115.E (versions 0001 or 0002) is updated to version 0003.

This software update ensures that the engine control unit operates correctly, preventing the recurrence of the Audi Q5 EPC light P060C00 and U041600 fault codes.

Important Warnings

For vehicles equipped with high-voltage components, a critical precaution must be observed during the software update process:

• High-Voltage Battery: "To prevent charging of the high-voltage battery during the software update, the high-voltage cable is to be removed BEFORE the entry of the SVM code on vehicles with high-voltage components. Charging the high-voltage battery during a software update cab damage the high-voltage components."

Warranty Information

This Technical Service Bulletin (TSB 2076356/2) provides guidelines for warranty claims. The service number for this procedure is 2470, with a damage code of 0039. Labor operations for the software update include codes 0150 0010 and 0151 0060. If your vehicle is outside of its warranty period, this bulletin serves as informational guidance for repairs.

Superseded Bulletins

TSB 2076356/2 replaces the previously issued Pending Service Solution (PSS) TSB 2072710, which also addressed engine control unit drive system faults P060C00 and U041600 for model year 2022-2024 Q5 40 vehicles.
