2024 Audi Q5 e B200000 Warning Message TSB

Symptoms

Owners of the 2024 Audi Q5 e quattro may observe a "Warning message in instrument cluster" appearing on their vehicle's dashboard. This message indicates a potential issue with the high-voltage battery charging system. If you experience an Audi Q5 e B200000 warning message, it's important to have your vehicle diagnosed.

Fault Codes / DTCs

When this condition occurs, workshop diagnostics will typically log specific event memory entries in the control unit for the high-voltage battery charging unit (diagnostic address 00C6).

Code	Description	Symptom Number	Status	Module
B200000	Control module faulty	1049088	active/static	J1050 (High-voltage battery charging unit)

This DTC B200000 indicates that the control module itself is reporting a fault, even if no hardware issue exists.

Technical Background

Audi has identified that the root cause for the "Warning message in instrument cluster" and the associated DTC B200000 is a software issue. The OBD (On-Board Diagnostics) system's sensitivity within the high-voltage battery charging unit control module (J1050) is too high, leading to erroneous fault detections. This means the module is reporting a fault when there isn't a genuine hardware problem.

Important Warnings

Audi has issued a critical warning regarding the repair process for this issue, specifically concerning the high-voltage battery:

"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."

This means technicians must take a specific safety precaution by disconnecting the high-voltage cable before proceeding with the software update to prevent potential damage to the high-voltage components.

Repair Procedure Summary

The repair for the Audi Q5 e B200000 warning message involves updating the software of the high-voltage battery charging unit control module, J1050 (diagnostic address 00C6). This procedure is detailed in Technical Service Bulletin 93 24 12 2075301/1.

1. DoIP Communication: Technicians must use DoIP (Diagnostics over Internet Protocol) when flashing control modules in supported vehicles. This requires specific settings in ODIS (Offboard Diagnostic Information System) under Administration>>General>>GFF Process>>DoIP communication>>Only allow DoIP communication. A red LED on the VAS 6154(A) diagnostic interface indicates active DoIP.
2. SVM Operating Instructions: All instructions in TSB 2011732, which covers Software Version Management (SVM) operating procedures, must be followed.
3. Software Update: The J1050 control module (00C6) needs to be updated using the SVM action code C6A014. This update will install new software to address the over-sensitive OBD diagnostics.

This TSB 93 24 12 2075301/1 replaces the previous Pending Service Solution (PSS) TSB 2074344 for the same issue.

Required Software / Part Numbers

The software update involves specific part numbers and versions:

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

Warranty Information

This Technical Service Bulletin 93 24 12 2075301/1 is applicable for warranty claims under specific conditions. If the vehicle is outside of its warranty period, the TSB serves as informational guidance only.

• Service Number: 9352
• Damage Code: 0039
• Labor Operations:
  • Software update: 0151 0010 (See SRT with associated operations)
  • Software update: 0151 0060 (Time stated on the diagnostic protocol)
• Claim Comment: As per TSB 2075301/1

All warranty claims must adhere to the Audi Warranty Policies and Procedures Manual.

Owner Action

If your 2024 Audi Q5 e quattro displays a "Warning message in instrument cluster" or you suspect an Audi Q5 e B200000 warning message, it is recommended to contact your authorized Audi dealer. They will be able to diagnose the issue, confirm the presence of DTC B200000, and perform the necessary software update on the high-voltage battery charging unit control module (J1050) as per TSB 93 24 12 2075301/1. This update is crucial to resolve the false fault detection.
