Hi Alz,
Mike's right about the coil packs these are covered by an additional warranty, so if the tell tale engine management light comes on and you experience a misfire, do not be fobbed off.
The 1,6 fsi is smooth running and works well with the A2. Gentle driving will see 50mpg, but at motorway speeds this will fall to 35-39mpg. A little hesitancy pulling away from lights and round-a-bouts is annoying but one learns to give a little more throttle.
There are some general things with the A2 which you will find on this website. I have owned my a2 for 4 1/2 years and am very happy with it. It's light, handles very well even though for some the sport ride is too hard for me it's just fine.
We use ours for a run about too, it's easier to park than "satans chariot" - thanks Mike! - our V70 Volvo.
Hope you enjoy the experience, there's really nothing else like it.
