2024 Audi Q5 e HV Charger Warning Message TSB 2074344/2

Owners of the 2024 Audi Q5 e quattro PHEV may encounter a warning message displayed on their instrument cluster related to the high voltage (HV) charger. This issue is documented in Audi Technical Service Bulletin (TSB) 2074344/2, which supersedes TSB 24-26 dated June 21, 2024. The TSB addresses specific diagnostic trouble code (DTC) B200000, indicating a control module fault.

Audi is currently developing a permanent solution for the 2024 Audi Q5 e B200000 issue, with availability expected in Q3 2024. In the meantime, Audi has provided a temporary workaround for owners experiencing this condition.

Symptoms

Owners will typically notice "A warning message is displayed on the instrument cluster." This message indicates a problem with the vehicle's high voltage charging system. This symptom is directly linked to the internal fault symptom 1049088.

Fault Codes / DTCs

When diagnosed, the vehicle's High Voltage Battery Charger control module -J1050- (address word 00C6) will log the following diagnostic trouble code:

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

This code specifically points to an internal fault within the HV charger control module. If your 2024 Audi Q5 e B200000 fault is present, it's important to follow the guidance in this bulletin.

Important Warnings for Owners

Audi explicitly states critical advice for this condition:

• "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!"

This means owners should not authorize any part replacements for the HV charger or related components if a dealer suggests it as a fix for the B200000 DTC before the official software solution is released. Such replacements will not resolve the underlying issue and may result in unnecessary costs.

Interim Solution and Workaround

While a permanent software update is being developed, Audi has provided a workaround for technicians to clear the DTC and for owners to manage charging.

Technicians are instructed to delete the DTC in the High Voltage Battery Charger control module -J1050- (address word 00C6) by following specific instructions found in the "q5instructions.pdf" document.

For owners, a specific procedure should be followed when charging the vehicle using the Universal Charging Cable (ULK) until the new software becomes available:

• When charging on 110V: Set the ULK to charge at 50% power. This can be done by long-pressing the button located above the Audi rings on the ULK itself.
• When charging on 220V: 100% charge power can be selected without issue.
• Public Level 2 Charging: Public level 2 charging infrastructure is not affected by this workaround, as these systems will always charge at 220V.

This temporary measure helps to manage the charging process and prevent the recurrence of the warning message and DTC B200000 until the permanent fix is rolled out.
