Bidirectional Diagnostic Tool for BMW/Rolls-Royce/Mini, BMM V3.0 All Resets/Battery Registration/ECU Coding Full System OBD2 Scanner for BMW Code Reader, Battery Test,Auto VIN-2025 Ver

Works great!!!

It doesn’t do anything my $60 scanner can’t do. I bought it specifically to reset the battery in my bmw and reset the engine learning cpu which YouTube recommended this model for. My check engine light. It’ll clear the code but it comes back after the monitors reset My scan tool already does that.

Compré este comprobador porque por desconectar el airbag sin haber desconectado la batería me saltó en el cuadro de un Montero v80 el error de airbag. En un taller me cobraban unos 20-40 euros por conectar la máquina pero por un poco más ya tengo yo el aparato para poder hacerlo y de momento ya lo he rentabilizado: en otra ocasión el coche no arrancaba, conecté este comprobador y me dijo que el problema era que el coche no detectaba en transpondedor de la llave. Abrir la llave, ver que el transpondedor estaba suelto, recolocarlo y arrancar de nuevo. Me ahorré otra visita al taller por una tontería!

Easy to use

Bought this to use on my MX5 Mk3 (NC) to diagnose an ABS fault showing on the dash, having seen from a few customer reviews that i909 included coverage of ABS for this vehicle. On my car, it came up with a couple of fault codes and descriptions for the right rear ABS, and these turned out to be a correct diagnosis (crack in toothed ring). The unit is compact and easy to use, and for occasional use I preferred an all-in-one unit like this to the types with a unit which plugs into the car and communicates via Bluetooth with an app running on a phone, tablet or laptop.
