The seals in my front caliper had swollen and weren't allowing the pistons to retract so the pads were dragging on the disc ever so slightly. This caused my MPG to fall to 50. Replaced the seals last week and I'm now back up to 60!
I've had the rears dragging before and that was due to the handbrake mechanism going dry in the rear calipers.
That happened to me on my old 405, I soaked the sliders in a load of brake fluid and freed them up little by little until the pins came out. Then loads of copper slip! I changed the pads all round on the HDI and copperslipped all the pins.
Cheers for that!

It's not that simple unfortunately, the ECU is coded to the immobiliser and the key fob chip.
You can use that remap on another HDi ECU though, as long as the ECU number matches exactly.
Thank you. If this experiment is a success I will be hanging on to the car until it falls to bits and then I will break it!
