Recently had my 2.0l Ecoblue Focus recalled for the update the Powertrain Control Module software, and since the update II have noticed a marked increase in fuel consumption. Anyone else noticed this?

    Is this an actual increase in fuel consumption where you have calculated a reduced mpg by recording how many miles you get between each tank fill? Or are you seeing a reduced mpg displayed in the car (which is just a calculated guess)? The calculated guess version displayed in the car does change between software versions sometimes.
