Good to know:
All BMW CAS4 CAS4+ Test Platforms support the same function. They can work alone to pinpoint whether it is caused by the mismatch between CAS4 CAS4+ and the key when the key can’t start the car.

Besides that, they also can work with some devices such as GODIAG GT100, CGDI, Xhorse VVDI 2, BMW VVDI BIM Tool, Autel IM608, Yanhua ACDP and Tango etc. to do more functions.

The difference is that they come from different factories and hardware.
Item No. SK228-G is out of stock, you’d better choose Item No. SK310 or SK228-G1.
