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.

Please take timestamped photos and videos at the first opportunity when picking up the car at the destination port (before leaving the port area). We will compare these with the final archived images taken at the Chinese port before shipping. If it is confirmed that we missed reporting it during the pre-shipment inspection, we will provide compensation for parts or labor costs based on the severity of the defect; if it is new physical damage incurred during shipping, the insurance claim process will need to be initiated.

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.
