Review on JOYING ELM 327 V2.1 Bluetooth OBD2 Diagnostic Tool: Android Car Interface Scanner for Vehicle Analysis by Virot Ngeonkham ᠌

I bought it to read errors on the Peugeot 308. I tried different programs, the verdict is the same everywhere - the device works, it reads the basic parameters, but as soon as it comes to reading errors or detailed parameters, then it's a bummer. Maybe on some cars it will work fine, but not on this one. In my case, it was possible to read only those parameters that the dashboard shows anyway.
