We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).

Internal logistics scheduling uses GPS, but direct access accounts are not open to the public. We implement a "node reporting system": our customer service will proactively send you on-site photos with watermarks at three key points: when the vehicle is loaded onto the trailer, when it arrives at the port for storage, and when customs clearance is completed.

It does not affect basic driving and regular speed cruise, but it will trigger a fault alert for advanced driver assistance on the dashboard. The LiDAR assembly is extremely expensive, so we focus on checking the integrity of the glass cover with a strong flashlight during inspections.
