What do you plan on changing with it Joe?
On the current car, nothing much (if anything), as I have a mate with VCDS who did most of the popular mods for me on this car when I first got it.
It's more for the new car, to do the same tweaks again and it'll be nice to have this tool myself so I can make quick adjustments without relying on asking my mate to do it.
I considered going the full hog and buying the VCDS cable but it's quite expensive and a bit overkill for my needs.
