Body components (structural/reinforcing/panels) have accident-related damage; passive safety devices are defective; vehicle performance (including three-electric system) has degraded or remains limited after repairs.
Accident inspection: main structure damaged, reinforcing parts undamaged, panels undamaged, hinges normal; engine bay: valve cover gasket oil leak; exterior: 2 repainted areas; interior: most features normal, airbag system normal, seatbelts normal, dashboard normal, instrument readings normal, lighting system normal; start-up check: major components normal; onboard tools: none.
Once the car system (especially in a closed ecosystem) undergoes a major version upgrade, its bootloader is usually locked, preventing downgrades. If this happens, there is basically no solution in an overseas environment. Therefore, we strongly warn: do not blindly insert a USB drive to upgrade while offline.
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.
4S dealership records are directly connected to the manufacturer's database, making the data hard to tamper with and the most reliable, with original parts guaranteed; third-party repair shops usually are not connected, making their data unverifiable. Therefore, we only consider the connected records from 4S dealerships as valid historical documentation.
