Hi all, Just wondering if those who have had both engines think that there is a big difference in the economy of the engines? Obviously there are different states of tuning but still. I currently have the 1.4tsi 150 act having come from a 2.0tdi 170 and I've got to say I'm very impressed. It's lovely and smooth/refined, economical (50+ mpg) most the time on a 10 mile plus run and will go if you give it some. I would just like to know how the 2.0 tsi compares.
