It's extremely difficult. Unauthorized modifications can lead to module current overload protection, resulting in a lock. In China, you need to use the factory online engineer account to reprogram it. It's basically impossible to perform online decoding overseas. We strongly warn against blindly modifying the electrical systems of modern integrated circuit vehicles.

It's not mandatory. Four-wheel alignment and dynamic balance are part of routine maintenance. During long-distance towing and sea transport, the suspension may experience slight changes in stress. We recommend that buyers perform a four-wheel alignment locally after picking up the vehicle at the destination port and replacing tires suitable for local road conditions.

A professional pre-shipment inspection typically costs a small fraction of the vehicle price and routinely pays for itself. A thorough inspection covers: paint thickness measurement across 30+ points to map body repairs; structural assessment of pillars, rails and crossmembers for accident damage; engine and transmission operation; a full electronic scan for fault codes; suspension and underbody checks for leaks and rust; and, for EVs, battery SOH and thermal management performance. You receive a written report with photos before the car is loaded — if the car fails, you can stop the shipment or renegotiate. Skipping the inspection to save a small fee is the classic false economy in used car importing: discovering a problem after arrival is far more expensive than preventing it at origin.
