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.

Ask the exporter for a paint thickness gauge report, or request a live video where they measure the car in front of you. What to look for: · Factory paint on most Chinese cars measures 80–120 microns. Readings above 150–200 microns on a panel usually mean repainting; above 300 microns often means body filler (putty) underneath. · Inconsistent readings between panels (e.g., left door 95µm, right door 180µm) suggest the right side was repaired. · Check gaps between panels (doors, hood, trunk). Uneven gaps or misaligned headlights/bumper clips point to past collision repairs. · Look for overspray on rubber seals, plastic trim, or inside door jambs — a clear sign of repainting. · Check bolt heads on fenders, doors, and hood. Wrench marks or fresh paint over bolts mean the panel was removed. Combine these checks with an OBD scan for airbag or crash-related fault codes. Any repainting should be declared by the seller; if discovered undeclared, you have grounds to renegotiate or reject the car.

The vehicle's "Motor Vehicle Registration Certificate" will clearly print the records of the mortgage and its release. Our legal and documentation team will strictly review during the vehicle collection process to ensure that the ownership is completely free and clear, preventing any future ownership disputes.
