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.

Testing is mandatory. Troubleshooting electrical devices in the car is part of the standard procedure. We will test the window lift motors, mirror folding, air conditioning compressor and fan, electric seat tracks, etc. Any stuttering or failure of electronic components will be recorded.

Plan for roughly 25-40% on top of the vehicle price. The main items are: 1. Pre-purchase: deposit (10-30%), third-party inspection fee (100-300 USD). 2. In China: inland trucking to the port, export declaration fees. 3. Shipping: ocean freight (container 20ft usually 1,500-4,000 USD depending on destination), marine insurance (about 0.3-0.5% of car value). 4. In your country: customs duty, VAT/GST, port handling and storage, customs broker, quarantine or pre-shipment inspection if required, registration and plates. Always ask the exporter for an itemized landed-cost estimate for your specific port before paying the deposit, and confirm which Incoterm the quote is based on (FOB, CIF or DDP makes a big difference).
