Body components (structural/reinforcing/panels) have accident-related damage; passive safety devices are defective; vehicle performance (including three-electric system) is degraded or remains performance-limited after repairs.
Accident inspection: main structure damaged, reinforcing parts damaged, panels damaged, hinges normal. Engine bay: no transmission disassembly record, valve cover gasket oil leak, valve cover gasket disassembly marks. Exterior: 2 replaced parts, 5 panel repairs, 3 paint jobs. Interior: most features normal, airbag test normal, seatbelts normal, dashboard normal, instrument test normal, lighting system normal. Start-up test: main components normal. Tool kit: absent.
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.
Experience turbo lag and power surge during road tests; check for significant oil accumulation at the turbo intake and intercooler connections (slight oil vapor is normal); and use OBD to read the real-time boost pressure peak to see if it meets factory settings.
We will never perform blind deep disassembly unless there are clear severe fault codes or extreme noises. The sealing of the engine and transmission is crucial, and compromising the factory seals to investigate non-existent issues is unprofessional. We rely on data flow and external acoustic and fluid analysis to make judgments.
