I am looking for one scanner to do injector check of my Hyundai i30 2008, I just bought this used car. Are there any differences between the original tool and clone tool? Not to say the price...I found the Fcar scanner which for diesel car
Fcar-F3-W (World Cars)
is it clone? $1800, this price seems not "clone"
How is this one? are all the online seller selling clone tools?

 

why to do injector check? 2008 Hyundai wasnt it still under warranty？
