We can purchase the hardware (diagnostic device) on your behalf. However, the original online diagnostic accounts (especially those involving anti-theft programming and module matching) have strict domestic IP location and real-name authentication restrictions, making it very difficult to log in stably from overseas for a long time, and we cannot guarantee technical support for this.

This is one of the most common post-export surprises, so verify before buying. OTA updates: most Chinese brands push updates to cars registered on domestic servers. Many exported cars continue receiving updates normally, but some brands restrict updates by VIN region once the car leaves China. Ask the seller to confirm the update history and whether the brand officially supports your destination region. Some grey-import cars are stuck on the firmware version they left with. Companion apps: the factory app usually requires a Chinese phone number and a domestic account. After export, remote functions (preconditioning, charging status, location) often stop working or require workarounds. Some owners re-register via third-party services, but this is unofficial and can break at any time. Practical advice: before purchase, get the seller to show a screenshot of the car's current software version and connected services status. Factor in that you may lose remote features permanently, and check whether local dealers or independent shops can perform diagnostics and updates without the official app.

Key documents to request and verify: 1. Export declaration (报关单): proves the car legally left China. Check the VIN, model and exporter name match the car. 2. Commercial invoice: must match your payment amount; customs uses it to assess duties. 3. Bill of lading: confirm the consignee is you or your agent, and the VIN/container number is correct. 4. Certificate of origin: needed for tariff preferences in some markets. 5. Condition/inspection report: ideally from an independent third party, with photos and dates. Verification tips: cross-check the VIN on every document — any mismatch causes customs holds. Ask your destination customs broker to review scanned copies before the car ships, and release the final payment only after documents pass that review. A legitimate exporter will provide all of these without hesitation.
