2024 Audi Q5 e Warning Message TSB for DTC B200000

Owners of the 2024 Audi Q5 e quattro may encounter a 2024 Audi Q5 e warning message displayed on their instrument cluster. This issue is addressed by Audi Technical Service Bulletin (TSB) 01 24 26 2074344/1, also referred to as 93 PSS HV Charger. The TSB confirms that a solution is actively being developed to resolve this concern.

This bulletin, dated June 21, 2024, provides guidance for dealerships on how to manage customer inquiries regarding this specific warning message. It outlines an interim workaround and emphasizes that no physical repairs or component replacements are needed at this time.

Symptoms

The primary symptom reported by owners is a warning message on the instrument cluster. This message indicates a potential issue within the vehicle's system. If you see a 2024 Audi Q5 e warning message, it is important to have your vehicle diagnosed by an authorized Audi service center.

Fault Codes / DTCs

When a technician investigates the instrument cluster warning, they will typically find a specific Diagnostic Trouble Code (DTC) logged. The TSB identifies the following:

• DTC B200000: Control module faulty (symptom 1049088) active/static. This DTC is found in the High Voltage Battery Charger control module -J1050-, specifically at address word 006C.

This fault code points to an internal issue within the battery charger control unit, which triggers the 2024 Audi Q5 e warning message.

Important Warnings for Owners

Audi has issued critical advisories regarding this condition:

• "No repairs are necessary at this point. Do not replace any components for this condition since this will not resolve the customer's concern."
• "Replacing parts or performing other procedures then specified in this PSS will not fix this complaint. Replaced parts and associated labor cost will be debited!"

These warnings mean that owners should not authorize any component replacements, such as the High Voltage Battery Charger control module, to address this specific warning message. Such actions will not fix the problem and may result in unnecessary costs. Audi is actively working on a software-based solution, expected to be available by Calendar Week 31/24.

Interim Solution and Workaround

Until the permanent software update is released, Audi has provided a temporary workaround for the 2024 Audi Q5 e warning message. If the TSB 2074344/1 applies to your vehicle, technicians are instructed to:

1. Delete the DTC: The diagnostic trouble code B200000 in the High Voltage Battery Charger control module -J1050- should be deleted. Specific instructions for this procedure are provided in an attachment titled "q5instructions.pdf" for technicians.
2. Adjust Charging Procedure: Owners must be informed to use a specific procedure when charging their vehicle with the Universal Charging Cable (ULK) until the new software is available. This involves:
   • When charging on 110V, set the ULK to charge at 50% power. This can be done by long-pressing the button above the Audi rings on the ULK.
   • When charging on 220V, 100% charge power can be selected.
   • Public Level 2 charging infrastructure is not affected by this workaround, as these systems will always charge at 220V.

Dealerships are also required to create a PSS record in the PSS application via AccessAudi to track instances of this issue.
