2021-2023 Audi e-tron Range Complaint TSB 2074440/1

What is this TSB about?

Audi Technical Service Bulletin 93 24 63 2074440/1, issued on July 1, 2024, offers essential information for technicians handling customer queries regarding range complaints in various Audi e-tron models. This document serves as a guideline to ensure that all necessary data is collected before a technical repair query can be processed effectively. It emphasizes the importance of thorough diagnostics to provide the best possible technical support.

Symptoms of Audi e-tron Range Complaints

Owners of 2021-2023 Audi e-tron vehicles might experience a perceived reduction in their vehicle's electric driving range. This could manifest as the vehicle not achieving its expected mileage on a full charge or displaying an inconsistent range estimate. These Audi e-tron range complaints prompt the need for detailed investigation by qualified service technicians.

Diagnostic Information for Technicians

To properly address Audi e-tron range complaints, technicians are instructed to perform several diagnostic steps. This includes checking for "event memory entries" in control units such as the 008C Hybrid battery management, 00C6 High-voltage battery charger, 0051 Electric drive, 00CE Electric drive 2, and 8104 Voltage converter. If such entries exist, "Guided Fault Finding" should be utilized.

Additionally, technicians must send a current diagnostic log online and read out all measured values from the 0019 Data bus diagnostic interface and 008C Hybrid battery management. It is critical to fully charge the high-voltage battery before reading out these measured values to ensure accuracy. The TSB also advises asking customers specific questions regarding the complaint's persistence, vehicle history, occurrence conditions (driving or stationary), navigation settings, air conditioning use, displayed range and charge level, charging history (aborted charges, AC/DC charging), charging timer/air conditioning timer activity, and external power consumer usage. A road test may also be required, with measured values recorded before and after.

Important Warnings for Owners and Technicians

Audi explicitly states that this Technical Service Bulletin 93 24 63 2074440/1 is solely for providing information on submitting technical repair queries. It "must not be used as workshop findings for the complaint and cannot be used for billing purposes." Furthermore, this TSB is "informational only and not applicable to any Audi Warranty." This means that while it guides the diagnostic process, it does not authorize specific repairs under warranty or serve as a basis for repair charges.

Next Steps for Owners

If you are experiencing range complaints with your 2021-2023 Audi e-tron, it is important to contact your authorized Audi service center. Be prepared to provide detailed information about when and how the issue occurs, as technicians will need this for their diagnostic process. While this TSB guides the data collection, it does not outline a specific repair, so the service center will use the gathered information to consult with Audi for further technical support.
