2024 Audi Q5 e Instrument Cluster Warning TSB

Owners of certain 2024 Audi Q5 e quattro vehicles may observe a "warning message in instrument cluster" appearing on their dashboard. This condition is often accompanied by a Diagnostic Trouble Code (DTC) B200000, indicating a fault within the control module. Audi has issued Technical Service Bulletin (TSB) 93 24 16 2075301/2 to address this specific concern, providing a software-based solution.

This TSB, dated September 23, 2024, supersedes previous guidance, including Technical Service Bulletin Group 93 number 24-12 dated September 17, 2024, and Pending Service Solution (PSS) TSB 2074344. The update applies to 2024 Audi Q5 e quattro models within the VIN range 000001-015509.

Symptoms

The primary symptom reported by owners is a generic "warning message in instrument cluster." This visual alert indicates an underlying issue that requires attention from a qualified technician.

Fault Codes / DTCs

When diagnosing the Audi Q5 e instrument cluster warning, technicians will typically find the following event memory entry logged in the control unit for the high-voltage battery charging unit (diagnostic address 00C6):

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

Diagnosis / Trigger Conditions

The root cause of the Audi Q5 e instrument cluster warning and DTC B200000 is identified as a software issue within the high-voltage battery charging unit control module, J1050. This software defect causes the On-Board Diagnostics (OBD) system to be overly sensitive, leading to the erroneous fault code and warning message.

Important Warnings

Audi has provided critical instructions for technicians performing this update:

• High-Voltage Battery Safety: To prevent charging of the high-voltage battery during the software update, the high-voltage cable must be removed BEFORE entering the SVM code on vehicles with high-voltage components. Charging the high-voltage battery during a software update can damage the high-voltage components.
• DoIP Communication: Always use DoIP (Diagnostics over Internet Protocol) when flashing a control module via ODIS in supported vehicles. To activate DoIP, technicians must select Administration>>General>>GFF Process>>DoIP communication>>Only allow DoIP communication. This setting will automatically reset after the diagnostic session. A red LED on the VAS 6154(A) diagnostic tool indicates active DoIP.

Repair Procedure Summary

The repair involves updating the software of the high-voltage battery charging unit control module, J1050 (address word 00C6). Technicians must follow the instructions detailed in TSB 2011732: 00 Software Version Management (SVM), operating instructions.

The update is performed using SVM action code C6A014. The software will be updated from an older version (e.g., Part Number 9Y0915681D, Version 3310) to a newer version (e.g., Part Number 9Y0915681Q, Version 3323 or higher).

Required Tools or Parts

Technicians will utilize the ODIS diagnostic system and a VAS 6154(A) interface for the software update. The specific new software part number required for the J1050 control module is 9Y0915681Q, or a later version.

Owner Action

If your 2024 Audi Q5 e quattro displays a "warning message in instrument cluster" or if you suspect your vehicle is affected by DTC B200000, it is recommended to contact an authorized Audi dealership. They can diagnose the issue and perform the necessary software update as outlined in TSB 93 24 16 2075301/2. This software update is typically covered under warranty for eligible vehicles.
