Reported symptoms

'Battery system service required' or 'Electric drive system fault' warning on cluster
Reduced charging speed, inconsistent charge curve, or charging session interruption
Reduced range or unexpectedly low state of charge readings
Manufacturer correspondence regarding battery inspection or seal-related service campaigns
Smoke, fire, or thermal event reported (rare but documented in regulatory filings during the recall period)
Service center indication that the battery requires sealed-system inspection

Questions to ask

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

Has VIN (Vehicle Identification Number) [VIN] been inspected per the active battery sealing and recall campaign, and what was the result of the inspection?
What is the production date of the high-voltage battery, and is this date within the affected scope of the campaign?
If rework or sealing was performed, what specific procedure was followed and what part numbers, if any, were replaced?
Were diagnostic trouble codes recorded, particularly any related to battery isolation, insulation resistance, or thermal management?
Is the issue being addressed under recall, under warranty, or as goodwill?
Has the battery's insulation resistance been measured and documented as part of the inspection?

Documents to request

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

Diagnostic report listing all stored and pending fault codes, including any related to insulation resistance and thermal management
Repair order with technician notes documenting the inspection scope and any rework performed
Written confirmation of the recall or campaign reference number applied to the VIN
Parts invoice listing part numbers and production dates of any components replaced
Battery insulation resistance reading taken at the conclusion of the inspection
Written warranty or recall classification determination

Pre-service evidence

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

Photograph cluster warning messages at the time they appeared
Save all Audi and dealer correspondence regarding battery inspections, recall notices, or service campaigns
Note odometer reading at drop-off and at pickup
Record battery state of charge at drop-off and at pickup
If the vehicle has been towed at any point, retain the tow receipt and any roadside assistance reports
Record the dealer name, technician name, and date of the inspection

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 work
Note whether the visit is classified as a recall, a service campaign, or a goodwill repair — these classifications affect future warranty rights and resale documentation
If the advisor states verbally that the vehicle is not subject to the campaign but the build date and battery production date fall within the affected scope, request written clarification before leaving the dealership
Document any verbal characterization of insulation resistance readings or fault codes that differs from the written diagnostic report

Repair authorization

Cautions before signing.

Recall remedies are performed at no charge to the owner; do not authorize any charge for parts or labor associated with the documented recall
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 battery work is proposed beyond the recall scope, request written warranty determination 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.

Confirm no warning messages on the cluster after a full ignition cycle and a complete charge cycle
Verify charging session initiates and completes normally on both AC and DC charging
Confirm range estimate at full charge is consistent with the vehicle's specification
Verify the repair order identifies the correct recall or campaign reference number
Confirm the parts invoice lists all components inspected or replaced, with part numbers and production dates
Retain a copy of the post-repair insulation resistance reading and any state of health data for ongoing reference

Service inquiry — e-tron battery system, request for written documentation scope

Service Department, I am scheduling my [YEAR] Audi e-tron, VIN [VIN], for evaluation of a high-voltage battery concern. Before the visit, I am requesting written confirmation of the following: 1. The current recall and service campaign status for VIN [VIN], specifically including any campaigns related to battery sealing or thermal management. 2. The scope of the planned inspection and any work to be performed, including whether insulation resistance will be measured and documented. 3. The expected duration of the service and any loaner vehicle arrangement. 4. Confirmation that recall remedies are at no charge to the owner. Please reply to this email so the planned scope is on record. Thank you, [NAME]

documentation request

Documentation request — e-tron battery service on [DATE], VIN [VIN]

Service Department, Following the inspection performed on [DATE] for VIN [VIN], I am requesting the following documents for my ownership records: 1. The full diagnostic report including all stored and pending fault codes. 2. The repair order detailing the inspection scope and any rework performed. 3. The parts invoice listing part numbers and production dates of any components replaced. 4. The post-repair insulation resistance reading. 5. The recall, campaign, or warranty classification applied to the visit. These documents form part of the vehicle's service record and are operationally important. Please reply to this email at your convenience. Thank you, [NAME]

Warranty notes

Audi has issued recall and service campaigns associated with the e-tron battery sealing concern in multiple regions. The applicable campaign for VIN [VIN] should be confirmed in writing.
The high-voltage battery is covered under Audi's electric component warranty. Coverage period and conditions vary by region and should be confirmed in writing.
Recall remedies are performed at no charge to the owner regardless of vehicle age, mileage, or warranty status. A recall remains open until performed.
Repairs performed under goodwill rather than warranty do not extend the warranty period. Confirm in writing which classification applies.

Observational patterns

Insulation resistance readings are part of the diagnostic data set for high-voltage battery inspections and can be requested explicitly. Verbal characterizations of battery condition are not a substitute for the recorded reading.

Battery production dates have varied across the rollout. Build date alone does not determine whether a vehicle falls within the affected scope; the battery production date is the operative reference and should be verified during inspection.

Goodwill classifications have been applied to some campaign-related work in service records. Goodwill classification does not preserve the recall paper trail in the same way that recall classification does, and the distinction has been cited in subsequent disputes.

Thermal management warnings can appear during charging or driving and are not always linked to a single root cause. Diagnosis through the full fault history, rather than the actively stored codes alone, improves the accuracy of the determination.
