Get the 2.0ltr TFSI one instead, easily remapped and quicker and simpler to mod. The V6 is thirsty and doesn't feel that fast, mate at work had one averaged 17-23mpg.....
I have the 2.0ltr TFSI S-line A3, brilliant trim spec solidly built. But they need frequent oil changes as I found recently after a garage missed a common fault with the pick up pipe getting blocked. My engine needed a rebuild.
