Reported symptoms
- Headlight fails to switch to high beam, low beam, or cornering mode as expected
- Adaptive headlight feature (Matrix LED or equivalent) does not modulate beam pattern in response to oncoming traffic
- Headlight warning message on cluster or driver display
- Headlight intensity reduced or beam pattern visibly incorrect against a wall at close range
- Manufacturer correspondence regarding headlight software-related recall or campaign
- My Porsche app reports vehicle errors related to lighting systems
Questions to ask
- Has VIN [VIN] been inspected per the active headlight software recall, and what was the result?
- What software version is currently installed on the headlight control module, and what version corresponds to the closed remedy?
- Is the regional variant of the software being installed, or a generic version that may not match the regulatory specification for this market?
Documents to request
- Diagnostic report listing all stored and pending fault codes from the headlight control module and related systems
- Written confirmation of the software version installed before and after the visit on the headlight control module
- Written confirmation that the regional variant appropriate to the registration market has been installed
Pre-service evidence
- Photograph or video-record any headlight defects at the time they occur — incorrect beam pattern, slow mode switching, intensity issues
- Save all Porsche correspondence regarding the recall, including any 'do not drive at night' or restriction advisories
- Note odometer reading at drop-off and at pickup
Service advisor interaction
- Record the full name of the service advisor and the technician performing the work
- Note whether the service is classified as recall, warranty, or goodwill — these classifications affect future warranty rights and resale documentation
- If the advisor states that an OTA update has been delivered for VIN [VIN] but the headlight behavior remains unchanged, request written documentation of the diagnostic steps before any release
- If the regional variant of the software is critical for the registration market, request written confirmation that the correct variant has been installed — generic global builds may not match local regulatory requirements
Repair authorization
- 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 diagnostic fees are presented, request written confirmation of whether the fee is refundable if the issue is later determined to be recall-covered
- Porsche dealers may bundle additional inspections or services with the recall visit; if these are presented as recommended, request the basis for each in writing before authorization
- Repair authorization signatures often include language permitting additional related work — read the document and decline blanket additional work in advance
Post-service verification
- Verify high beam, low beam, and adaptive functions operate correctly during a short night-time test drive if conditions allow
- Verify beam pattern visually against a wall at close range — uneven distribution, dark spots, or incorrect cutoff lines may indicate the remedy is incomplete
- Confirm no headlight-related warnings on the cluster or driver display after a full ignition cycle
- Verify the My Porsche app maintains stable connectivity and reflects accurate vehicle status
- Confirm the repair order matches the work performed and references the correct recall campaign number
- Retain copies of all post-repair documentation in case of recurrence

Warranty notes
- Porsche has issued recall and service campaigns associated with Macan EV headlight software defects. The applicable campaign for VIN [VIN] should be confirmed in writing.
- Headlight components are covered under the Porsche New Vehicle Limited 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 or recall do not extend the warranty period. Confirm in writing which classification applies.
Observational patterns
Headlight software defects can affect compliance with regional lighting regulations. The classification of the defect — convenience or safety — affects how the campaign is documented and may influence resale documentation in regions with annual safety inspections.
OTA delivery does not always produce a corresponding entry in the dealer-side service record. The closure of a recall delivered over the air requires explicit documentation through the dealer system.
Adaptive lighting systems use multiple sensor inputs and software logic; a recall remedy that addresses the software does not necessarily resolve sensor or hardware-driven defects in the same system. Verification of correct beam behavior after the remedy is operationally important.
Regional software variants matter for vehicles imported from other markets, leased internationally, or registered in regions with stricter lighting regulations. Confirmation that the correct regional variant is installed is operationally distinct from confirmation that 'a software update has been applied.'
