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).

Most basic maintenance reminder lights (like for changing the air conditioning filter) can be manually cleared using a combination of steering wheel buttons or through the engineering mode on the central control screen. We will provide internal guidance manuals for these hidden operations to our B2B clients.

Compliance with the law is an absolute requirement for exports. All vehicles exported through our platform must complete the following legal processes: release all domestic bank mortgages, pay all traffic fines, and complete the formal deregistration for "transfer pending export" with the Chinese public security traffic management department. Only vehicles with 100% clear ownership can be approved for export permits.
