I Just got my Audi A6 avant and am looking to do something with the diagnostics outputting to a pda screen that will run a VB program to allow me to manage my music and pull in my cars diagnostics status to a GUI

Has anyone done something like this?
Can anyone recommend a diagnostics product?
Is there any way i can get a parts catalogue where it has three dimensional views etc like the Audi Service Center has?

Thanks

 

What year - what motor?
