Hi. I have got a brand new (63 reg) Galaxy 2.2Tdci Powershift and the fuel consumption is just dreadful. I was down to 32.2 mpg on average. It has been back to a main dealer who can find no fault. I currently have a tuning box fitted from www.tdi-tuning.co.uk in Chelmsford but after initial high hopes, I am now only getting 33 ! I live in the country, so don't do much motorway driving but my average of 32 did include quite a few decent length motorway journeys. But it's not like I live in the city either. I just fail to understand how my previous Galaxy averaged 42 and now I have a 10% bigger engine (and an auto) that the fuel consumption could drop by 25% !! Has anyone else experienced this, or was I just stupid to buy the 2.2 in the first place ? I have friends with 2.2 Tdci Honda's who are getting 40's and 50's ! It seems madness really Any help would be appreciated. Barkster.
