2024-2025 Audi Q5 e Warning Message in Instrument Cluster

Symptoms

Owners of 2024-2025 Audi Q5 e quattro vehicles may observe a "warning message in instrument cluster" while driving. This message indicates an issue with the vehicle's high-voltage system.

Fault Codes / DTCs

Upon diagnosis, technicians will find the following event memory entries logged in the control unit for the high-voltage battery charging unit (diagnostic address 00C6):

• DTC B200000: Control module faulty (symptom 1049088) active/static.

Technical Background

Audi has determined that the root cause of the "Audi Q5 e warning message" and associated DTC B200000 is a software issue. The OBD (On-Board Diagnostics) system's sensitivity is too high, leading to incorrect fault detection within the high-voltage battery charging unit control module, J1050.

Production Solution

This condition has been addressed in production by implementing new software in the high-voltage battery charging unit control module, J1050 (address word 00C6).

Repair Procedure Summary

Technical Service Bulletin 2075301/3 provides instructions for resolving the "Audi Q5 e warning message" by updating the software of the J1050 control unit. This TSB supersedes previous bulletin PSS 2074344. The repair involves using the SVM (Software Version Management) system with the specific SVM action code C6A014.

Technicians must follow all instructions detailed in TSB 2011732 for SVM operating procedures. The software update will replace older software versions (e.g., 3310 with part number 9Y0915681D) with newer versions (e.g., 3323 with part number 9Y0915681Q).

Important Warnings

Owners and technicians should be aware of critical steps during the software update process:

• "To prevent charging of the high-voltage battery during the software update, the high-voltage cable is to be removed BEFORE entry of the SVM code on vehicles with high-voltage components. Charging the high-voltage battery during a software update can damage the high-voltage components."
• "Always use DoIP when flashing a control module via ODIS in supported vehicles. To Activate DoIP, select Administration>>General>>GFF Process>>DoIP communication>>Only allow DoIP communication. This setting will automatically reset when the diagnostic session has ended. You can tell if DoIP is active by observing a red LED on the VAS 6154(A)."

Required Software / Part Numbers

To perform the software update, the following software versions and SVM code are relevant:

• Old Software Part Number: 9Y0915681D
• Old Software Version: 3310
• New Software Part Number: 9Y0915681Q (or higher)
• New Software Version: 3323 (or higher)
• SVM Code Input: C6A014
