2024-2025 Audi Q5 e Check Engine Light After Charging TSB

Audi has issued an On-car analysis list, dated February 10, 2025, to address a specific concern affecting 2024-2025 Audi Q5 e (PHEV) vehicles. This document, similar to a Technical Service Bulletin (TSB), provides guidance for technicians regarding a check engine light that may illuminate after the vehicle has been charged. Owners experiencing an Audi Q5 e check engine light after charging should be aware of this communication.

Symptoms

Owners of affected Audi Q5 e models may observe the check engine light illuminating on their dashboard shortly after the vehicle completes a charging cycle. This warning light indicates that the vehicle's onboard diagnostic system has detected a potential issue within the powertrain or emissions control system. While the vehicle may appear to operate normally, a persistent check engine light requires attention to prevent potential long-term damage or performance degradation.

Fault Codes / DTCs

When diagnosing the check engine light concern, technicians are instructed to check the vehicle's Diagnostic Trouble Code (DTC) memory. The specific DTC associated with this issue is POE5E00, which points to a "BATTERY CHARGER CONTROL MODULE PROCESSOR PERFORMANCE" fault. This code is typically stored in the 008C module, indicating a problem with the processor responsible for managing the battery charging process in the plug-in hybrid electric vehicle (PHEV) system.

Diagnosis and Next Steps

The diagnostic procedure outlined in the Audi On-car analysis list is concise. Technicians are advised to first verify the customer's reported concern regarding the check engine light after charging. Following this, they must check the DTC memory for the presence of code POE5E00. Crucially, the document directs technicians to "Contact TAC for further direction." This indicates that the specific repair steps are not standardized and require direct consultation with Audi's Technical Assistance Center (TAC) for guidance on resolving the Battery Charger Control Module Processor performance issue.

Important Advisories

Audi emphasizes several critical points for technicians and service centers. The document states, "Please contact Audi Helpline before attempting repair." This highlights the complexity or novelty of the issue, requiring expert consultation prior to any repair work. Additionally, it references "TSB 2066297 '00 VIN-4-PIN reporting program (V4P, vin4pin)" for more information about the program, suggesting that this specific issue is part of a broader data collection or analysis initiative by Audi.

What Owners Should Do

If you own a 2024 or 2025 Audi Q5 e and experience a check engine light after charging, it is important to schedule an appointment with an authorized Audi service center as soon as possible. Due to the requirement for technicians to "Contact TAC for further direction," the diagnostic and repair process may involve specialized guidance from Audi. It is advisable to mention the specific symptom and, if possible, refer to the Audi On-car analysis list from February 10, 2025, or DTC POE5E00 when speaking with your service advisor. As this is a manufacturer communication addressing a specific fault, the repair is likely covered under the vehicle's warranty.
