Symptoms of the "Electrical System Malfunction"

If you own a 2021-2022 Audi Q5 e and experience an Audi Q5 e electrical malfunction, you will typically notice a specific warning message. The primary symptom reported by customers is the illumination of an "electrical system malfunction" warning light. Concurrently, the vehicle may exhibit a "will not go into drive" condition, rendering the vehicle inoperable and preventing normal operation. This combination of warnings and functional limitations points to a significant issue within the vehicle's hybrid electrical system.

Diagnostic Trouble Codes (DTCs)

When diagnosing the Audi Q5 e electrical malfunction, technicians are likely to find specific Diagnostic Trouble Codes (DTCs) stored in the Hybrid Battery Management control unit, identified as J840 (address word 008C). These codes indicate communication issues or voltage problems within the hybrid system's intricate network. The presence of these DTCs is crucial for identifying the affected area and guiding the diagnostic process. The following DTCs are commonly associated with this condition:

Technical Background and Audi's Investigation

Audi has noted that various parts have been replaced under warranty in an attempt to resolve the reported "electrical system malfunction" condition. However, these replacements have not consistently identified or resolved the underlying issue. To better understand the root cause and gather crucial diagnostic information, Audi is requesting that technicians contact the Audi Technical Assistance Center (TAC) before replacing any parts related to these DTCs. This proactive approach, detailed in TSB 2081028/1, aims to assist in accurately diagnosing potential issues by collecting real-world data from affected vehicles. This prevents unnecessary part replacements and ensures that a comprehensive solution can be developed based on actual fault patterns.

Important Warnings for Owners and Technicians

This TSB, identified as 2081028/1, is purely informational and does not constitute a warranty claim or a recall. It is explicitly stated that this bulletin is "not applicable to any Audi Warranty" for direct repair. For vehicles still covered under the New Vehicle Limited Warranty, technicians must contact a TAC consultant for guidance before proceeding with any repairs. It is crucial to attach all relevant DTCs and diagnostic logs to the TAC Web Ticket to support Audi's data collection efforts. Technicians are advised: "Do not replace parts" without prior consultation with TAC, as this will not resolve the underlying issue and may lead to wasted resources. Owners should be aware that this is an information-gathering phase, not a definitive repair instruction, and their cooperation in allowing data collection is vital.

Production Status

Audi has confirmed that no changes have been made to vehicle production regarding this specific condition. This indicates that, as of the release date of this bulletin, no systemic manufacturing issue has been identified or rectified in the production line for the Audi Q5 e electrical malfunction.
