My .02 is if you plan on owning more VAG cars in the future to get the Pro function with OBD11 since Carista charges an annual charge of nearly $40 US. Where as OBD11 is like $70 and it's good forever. I personally use OBD11 and find it more than worth it. I tend to meet up with other MK7 owners from a FB page I belong to in the Chicago area so they can run diagnostics on their Audi/Vw's. Either route you go will be up to what interface you prefer and what you want to pay right now to use it. I looked at the long haul so decided to go all in with it.
