Hi the cable will not work on its own its an interface that will have to be connected to a laptop that already has the appropriate software on it, the cable on its own is useless otherwise as you need something to connect it to, other than that pay your local independent garage to put it out with their scanner, if you own a car 2000 onwards some sort of VAG software device is a crucial part of maintaining your own vehicle, I put my service light and inspection due to bed with mine.
