"Saved our workshop hours of trial and error. They diagnosed a Li Auto L8 fault in under an hour — we had the part ordered from Guangzhou the same day. Best investment we've made this year."

The Challenge
No clear fault code, no direction — and the car is stuck in your bay.
BYD, Li Auto, Zeekr systems are region-locked. You can't log in.
Documentation is in Chinese. Technical data is hard to source.
Blind guessing costs money and time. You need the root cause first.

We identify the root cause using OEM tools in China — no guessing, no trial and error.
Step-by-step instructions via WhatsApp or WeChat — our engineer walks you through every step.
Once the fault is confirmed, we supply the exact parts — sourced from our Guangzhou warehouse.
Simple Process
Plug the Smartlink C into the OBD port and connect to our gateway.
Our engineers in China access the vehicle data and pinpoint the fault.
Follow our step-by-step instructions to complete the repair on-site.
