2007 Audi S5 (New Zealand)
 

hi guys.
I have a 2007 Audi S5, V8 model, 6 speed, NZ New.
id like to have daytime running laptops going and Audi said they can do it for $150 + diagnostic fee.
i figure buy my own VAG tool and do it myself, and then i have the tool to do other things later on.
my questions are:
1) whats the best VAG tool to buy? are the ones on ebay suitable ?
2) what software do i need?
3) can i update the MMI system with it also ?

on a side note, just got my car back from mechanic after having the clutch replacement to solve the not starting when clutch pushed in problem, AMAZINGLY different now !! omg.. the lightest touch of the key and just over a half push on the clutch and she starts perfect everytime :)
