I've got the same engine in my Scirocco and its great. Very responsive, torquey and can easily do 50+ mpg on a run. They are also very tuneable too
Not a bad sound out of them either - for a diesel. The DPF makes sure you don't get a hint of smoke out of the back and the tail pipes NEVER get sooty ,
I've activated the XDS on VAG COM - the GTD has it turned on from the factory, is recommend switching the setting up to 2 on VAG COM for the full effect. With the XDS it's incredibly capable out of the corners, I'm amazed how much grip it gives you
You can also activate needle sweep and loads of other options with VAG COM
