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).

We can purchase the hardware (diagnostic device) on your behalf. However, the original online diagnostic accounts (especially those involving anti-theft programming and module matching) have strict domestic IP location and real-name authentication restrictions, making it very difficult to log in stably from overseas for a long time, and we cannot guarantee technical support for this.

Chinese standard electric vehicles use the national standard (GB/T) charging interface. If your country uses the European standard (CCS2), American standard (CCS1), or Japanese standard (CHAdeMO), the vehicle cannot be plugged directly into local charging stations. To address this issue, we will recommend or provide high-quality certified adapters (Adapter) with CE/UL safety certification. Please confirm the charging station specifications in your area with our sales personnel before purchasing.
