Mini cooper d clubman poor mpg
I'm new to this forum and just purchased a used mini cooper d hampton. Very pleased with the car but a bit disappointed with mpg I'm getting. When I first received the car I reset the mpg on the system and after the first tank of fuel got a read out of 34.8mpg, filled up a few days ago and done the reset, now getting just over 32mpg. I have taken it back to dealer who agreed that was low and took it for a day to test out and said there were no errors on the system. The car has done 10,000 miles so the wearing in period has passed and my trip to work is about 12 miles dual carraigeway and town driving. Was driving a diesel Audi A6 2.0tdi before this and was getting between 34-37mpg so was hoping for at least mid 40's. Anyone else had such poor mpg? I've checked tyre pressure, not carrying any heavy loads, don't break heavily and change gear when the indicator tells me to. Any suggestions to try and improve the fuel economy?
