OBD Auto Doctor supports all cars sold worldwide compatible with OBD2 or EOBD. Please see https://www.obdautodoctor.com/help/articles/obd2-compatible-cars/ for the compatibility info.

The app requires a separate OBD adapter using Bluetooth, BLE, or Wifi. Plug the ELM 327 compatible scan tool into the car's diagnostics port, and make sure you are ready for car inspection. We recommend avoiding the cheap clone ELM devices and using genuine ELM327 adapters.

NOTE: Most app features require your car to support them. This app can't show information that your vehicle doesn't provide.
