I've been running my TD chipped for the last few years, and recently went back to the entry level chip to protect the AR25 box until I get round to fitting the AR35 sitting in my garage.

I am concerned that my consumption, empirical and computer readout, shows that I am only getting around 24.5 mpg running around on short journeys, and 32 on a run. Before the car was originally chipped in 2007, I was getting about 26/35.

The car has been extremely well serviced in accordance with OOF recommendations. Milage is 105K.

Any suggestions as to how I might restore its mpg, other than re-chipping? :-?

That's about right for an auto-boxed TD Chris me boy! :-?

It was definitely better a few years ago Byron. :'(

try running with the econ button pressed when the aircon is not needed.

Fair point, but I never bothered with  that before when I was getting better mpg. :-/
