Had a chance to use my set-up on my new M235i today, and it worked great. Read both Oil and Coolant temp. My OBD Wifi adapter is the old version of
this one (LYL brand), and looks almost exactly like
this one. I use the
OBD Fusion app.
Once set-up, which consists solely of connecting to the wi-fi network the adapter creates, it auto-connects on start up, and all you have to do is launch the app and tap connect and in a few seconds you are good to go.
