LAUNCH CR319, as a practical OBD2 portable scan tool specially designed to work with all OBDII/CAN compliant vehicles, featuring full OBDII functions, DTC lookup with multi-languages support etc., is a great choice for any beginners and average car owners to facilitate their vehicle repair work.
It is ok for detecting and hopefully to reset engine fault codes,
On z4 BMW but a lot off functions come up with not compatible with this vehicle.
As Long as it reset code I will be happy as this is what I brought it for otherwise I will be back to complain bitterly.
I sure this device works but there are no instructions in how to use it. The quick starter guide that comes with the unit is very brief and is a bit strange.
