2024 Audi Q5 EPC Light & Drive System Fault TSB

Audi has released Technical Service Bulletin (TSB) 2076356/1 to address specific engine control unit drive system faults in the 2024 Audi Q5. Owners may notice an illuminated EPC light or a general drive system fault message appearing in the instrument cluster. This TSB outlines a software update procedure to correct the underlying issue.

This bulletin, dated December 18, 2024, supersedes the previous Pending Service Solution (PSS) TSB 2072710, which also covered engine control unit drive system faults P060C00 and U041600.

Symptoms

Owners of affected 2024 Audi Q5 vehicles may observe one or both of the following conditions:

• The "EPC light is on" warning indicator is illuminated on the dashboard.
• A "Drive system fault appears in the instrument cluster" message is displayed.

These symptoms point to a potential issue with the engine's control systems, indicating that the 2024 Audi Q5 drive system fault requires attention.

Fault Codes / DTCs

When diagnosing the 2024 Audi Q5 drive system fault, technicians using a diagnostic tool will find specific event memory entries logged in the engine control unit. The following Diagnostic Trouble Codes (DTCs) are associated with this condition:

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

Diagnosis / Trigger Conditions

Audi has identified the root cause of these DTCs and symptoms as a software issue within the engine control unit, specifically the -J623- module (address word 0001). The new software version directly addresses this condition, ensuring proper performance and communication within the vehicle's systems.

Important Warnings

Before proceeding with the software update, Audi provides a critical warning for vehicles equipped with high-voltage components:

"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."

This step is crucial to prevent potential damage to sensitive high-voltage components during the update process.

Repair Procedure Summary

The repair for the 2024 Audi Q5 drive system fault involves updating the software of the engine control module. The general procedure is as follows:

1. Preparation: For vehicles with high-voltage components, the high-voltage cable must be removed before entering the SVM code to prevent battery charging during the update. This is a critical safety and component protection step.
2. SVM Instructions: Technicians must follow all instructions detailed in TSB 2011732, which covers the Software Version Management (SVM) operating procedures.
3. Software Update: The engine control module, -J623- (address word 0001), is then updated using the specific SVM action code provided by Audi.

Required Software and SVM Codes

To perform the software update for the 2024 Audi Q5, the following software and SVM code are necessary:

• Affected Model: MY24 Q5
• Old Software Part Number: 80A.907.115.E (Versions 0001, 0002)
• New Software Part Number: 80A.907.115.E (Version 0003)
• SVM Code Input: 01A267
