Reported symptoms

DC fast charging session refuses to initiate, terminates early, or sustains charge rate well below specification (Q8 e-tron supports up to 170 kW (kilowatt, a unit of power) peak)
AC charging session terminates early or fails to complete to the requested state of charge
Charging session terminates with high-voltage system error or 'Service charging system' message
Cluster, head-up display, or driver-information display flickering, partially blank, or showing intermittent warnings
Driver-assist features inactive, intermittent, or behaving inconsistently
myAudi app reports charging-session inconsistencies or vehicle errors

Questions to ask

Pose these to the service advisor at intake. Request answers in writing or via email.

Has the Audi dealer confirmed in writing that any campaign applied to VIN (Vehicle Identification Number) [VIN] is Q8 e-tron-specific (2024 rebrand), rather than an original e-tron (2019-2022) campaign that may not apply due to the BMS (Battery Management System) and software refresh?
Has VIN [VIN] been inspected per the original e-tron battery thermal recall, and was the determination that the recall does or does not apply documented in writing?
What software versions are currently installed on the BMS, charger, and infotainment modules?
Were diagnostic trouble codes recorded? Specifically, were any codes related to charging, contactor state, or thermal management logged?
Is the issue being addressed under the EV component warranty, the basic warranty, or as goodwill?
Has the issue been reproduced at an Audi-authorized fast charger, or only on third-party networks?

Documents to request

Each item should be received in writing before authorizing repair work.

Diagnostic report listing all stored and pending fault codes from the high-voltage and charging systems
Repair order with technician notes, including any reference to Q8 e-tron-specific or original e-tron service campaigns or bulletins, with explicit clarification of which apply
Written confirmation of software versions installed before and after the visit on the relevant modules
Written warranty determination — written, not verbal
Written confirmation of whether the original e-tron battery thermal recall applies to VIN [VIN]

Pre-service evidence

Capture before drop-off. Once the vehicle leaves your possession, proving prior condition becomes significantly harder.

Screenshot the myAudi app charging history, showing failed or abnormal sessions with timestamps and session details
Save records from third-party charging network apps showing failed session details
Photograph cluster warning messages at the time they appeared
Note ambient temperature conditions during which the issue has been observed
Confirm written documentation explicitly identifies the Q8 e-tron (2024 rebrand) and clarifies which original e-tron campaigns do or do not apply
Note odometer reading at drop-off and at pickup

Service advisor interaction

Operational notes specific to the conversation at the service desk.

Record the full name of the service advisor and the technician performing the diagnostic
The Q8 e-tron is the 2024 rebrand of the original e-tron (2019-2022), with substantial software and BMS refresh. Service interactions can conflate the two — verify in writing whether any campaign or technical bulletin reference applies to the Q8 e-tron specifically or originated with the older e-tron.
Note whether the issue is characterized as 'unable to reproduce,' 'within specification,' or 'normal operation' — these classifications carry downstream consequences for warranty claims
If the dealer indicates the original e-tron battery thermal recall applies to VIN [VIN], request the campaign reference number and the basis for inclusion in writing

Repair authorization

Cautions before signing.

Recall and software campaign work is performed at no charge to the owner; do not authorize any charge for parts or labor associated with these campaigns
If a diagnostic fee is presented, request written confirmation of whether the fee is refundable if the issue is later determined to be recall- or warranty-covered
If high-voltage component replacement is quoted, request written warranty classification before signing the repair authorization
Repair authorization signatures often include language permitting additional related work — read the document and decline blanket additional work in advance

Post-service verification

Complete before leaving the service location. Issues that surface after departure are operationally harder to attribute to the visit.

Conduct a verified DC fast charging session at a CCS-compatible fast charger before traveling more than a short distance from the dealership
Verify Level 2 (AC) charging initiates and completes normally
Confirm no warning messages on the cluster after a full ignition cycle and short drive
Verify the myAudi app reflects accurate charge state and battery health indicators
Confirm the repair order matches the work performed and references the correct campaign or bulletin (with platform clarification)
Retain copies of all post-repair documentation in case of recurrence

Service inquiry — Audi Q8 e-tron charging system, VIN [VIN]

Service Department, I am bringing my [YEAR] Audi Q8 e-tron, VIN [VIN], in for evaluation of a charging system concern. Symptoms observed: [LIST SYMPTOMS WITH DATES, NETWORKS, AND SESSION DETAILS WHERE AVAILABLE]. Note: VIN [VIN] is a Q8 e-tron (2024 rebrand of the original e-tron 2019-2022). Service interactions sometimes conflate the two, but the Q8 e-tron has a substantial BMS and software refresh. Before the visit, I am requesting written confirmation of the following: 1. Whether VIN [VIN] is subject to any open service campaign, technical service bulletin, or recall related to the charging or high-voltage system — specifically as a Q8 e-tron, with clarification of which original e-tron campaigns apply. 2. Whether the original e-tron battery thermal recall applies to VIN [VIN]. 3. The diagnostic plan for this visit, including the interrogation of historical fault codes. 4. The current software versions on the relevant modules and any updates planned during this visit. 5. The fee structure, including any diagnostic charges and conditions under which they apply. Please reply to this email so the planned scope is on record. Thank you, [NAME]

Warranty notes

Audi Q8 e-tron components are covered under Audi's New Vehicle Limited Warranty and the high-voltage battery component warranty (8 years / 100,000 miles in most US markets). Coverage period and conditions for VIN [VIN] should be confirmed in writing.
The Q8 e-tron is the 2024 rebrand of the original e-tron (2019-2022). Service campaigns issued for the original e-tron may or may not apply to the Q8 e-tron depending on the specific defect and production date. Confirm any campaign reference in writing.
The Q8 e-tron is a different platform from the PPE-based Q6 e-tron and A6 e-tron, and from the MEB-based Q4 e-tron. Service campaigns issued for those platforms do not apply to the Q8 e-tron.
Recall remedies, when issued, are performed at no charge to the owner regardless of vehicle age, mileage, or warranty status.

Observational patterns

The Q8 e-tron (2024+) is the rebrand and refresh of the original Audi e-tron (2019-2022). Service interactions can conflate the two due to the shared platform and similar appearance, but the Q8 e-tron has substantial software and BMS updates that affect campaign applicability.

Campaign coverage for the original e-tron may or may not apply to the Q8 e-tron, depending on the specific defect and production date. Owner-side awareness of the platform distinction is operationally important to avoid mistaken campaign exclusion or inclusion.

The Q8 e-tron is on the older MLB-derived platform, distinct from the newer PPE platform (Q6 e-tron, A6 e-tron, Macan EV) and MEB platform (Q4 e-tron). Service-system records should clearly identify the platform.

Charging session failures are sometimes attributed to charging network behavior. Vehicle-side BMS logs are the more reliable source for determining whether the vehicle terminated the session.
