Okay so, I've been looking at getting a vag-com for my '99 audi a4. really the only reason i want it is to do diagnostics on my audi without taking it to a dealer and getting charged for it. But i have no idea what i need and where to begin. So what tools, software, cables, ect. do i need and where can i get them at? thanks a lot for the help!

 

how about the X431 IDiag Auto Diag Scanner for Android,used on Android operation system smart phone or pad.
