Pose these to the service advisor at intake. Request answers in writing or via email.
Were stored, pending, or historical charging, BMS, thermal-management, or high-voltage codes found?
What software versions were installed before and after service?
Was the issue reproduced using AC charging, DC charging, or both?
Is the remedy software-only, calibration-related, or hardware-related?
If charging infrastructure is blamed, what vehicle-side evidence supports that conclusion?
Will the repair order document whether the vehicle is safe to operate after service?
Documents to request
Each item should be received in writing before authorizing repair work.
Repair order with technician notes
Diagnostic report listing charging, BMS, thermal-management, and high-voltage codes
Written confirmation of software versions before and after service
Charging-session logs or dealer test results if available
Written warranty classification and safe-to-drive confirmation
Closed repair order showing final remedy
Pre-service evidence
Capture before drop-off. Once the vehicle leaves your possession, proving prior condition becomes significantly harder.
Save charging-network receipts and session logs
Photograph cluster warnings and charging errors
Screenshot Porsche app charging status and failures
Document charger type, station power, ambient temperature, and state of charge
Record odometer reading at service drop-off and pickup
Retain towing or roadside-assistance records if the vehicle became disabled
Service advisor interaction
Operational notes specific to the conversation at the service desk.
Ask Porsche to document whether charging failures were vehicle-side or infrastructure-related.
If a software update is applied, request before-and-after software versions.
If the issue cannot be reproduced, request written confirmation that historical fault logs were reviewed.
Charging complaints should not be closed with generic 'could not reproduce' language without documenting testing conditions.
If the remedy involves thermal-management calibration, request written confirmation.
Repair authorization
Cautions before signing.
Do not authorize paid charging-system diagnostics until warranty classification is clarified in writing
If hardware replacement is proposed, request written warranty determination before approval
Separate unrelated maintenance from charging-system work before approval
Review authorization forms carefully before approving additional repairs
Post-service verification
Complete before leaving the service location. Issues that surface after departure are operationally harder to attribute to the visit.
Verify AC charging initiates and completes normally
If practical, verify DC fast charging behavior before relying on the vehicle for travel
Confirm no charging or high-voltage warnings remain after a full drive cycle
Confirm software version and remedy are documented
Monitor the first several charging sessions after service
Save the closed repair order

Service inquiry — Porsche Macan EV charging concern
Service Department,
I am scheduling my [YEAR] Porsche Macan EV, VIN [VIN], for a charging-related concern.
Observed symptoms:
[DESCRIBE AC/DC CHARGING FAILURE, WARNINGS, CHARGER TYPE, STATE OF CHARGE, TEMPERATURE, AND DATES]
Please confirm in writing:
1. Whether stored, pending, or historical charging/BMS/high-voltage faults were found.
2. Software versions before and after service.
3. Whether the issue was reproduced using AC, DC, or both charging methods.
4. Whether the remedy is software-only, calibration-related, or hardware-related.
5. Whether infrastructure-related causes were ruled out.
6. Warranty, campaign, goodwill, or customer-pay classification.
Please include these findings on the repair order.
Thank you.
Warranty notes
Macan EV charging, thermal-management, and high-voltage systems should be evaluated under Porsche's applicable EV warranty terms for VIN (Vehicle Identification Number) [VIN].
Software-only remedies do not extend warranty unless Porsche states otherwise in writing.
Goodwill repairs do not extend warranty coverage. Confirm classification in writing.
Repeated charging failures should be documented as recurring service history if symptoms return.
Observational patterns
Charging complaints should document charger brand, power level, state of charge, ambient temperature, and whether battery preconditioning was active.
If Porsche attributes the issue to infrastructure, request written confirmation of what vehicle-side diagnostics were performed.
Intermittent charging failures should be documented separately for AC and DC charging.
