Does the FL2 engine run ok with the EGR blanked off? I thought it sensed the gas flow and then throws up a fault if it sensed that the flow is too low.Seem low to me. Must be your driving style
Snick into sports mode and drive it like you stole it will return a lot less than 30mpg.
Drive it like your granny and you’ll get 32~33 mpg.
Blank off the EGR and change the gears manually and you’ll achieve 37 mpg.
Zero the computer on a long stretch of 60mph road with average speed cameras and it will settle down at 40+ mpg.
All these figures can be upped by 2~4 mpg by using premium fuel.
That’s my experience.
No MPG display is accurate, quite the opposite in fact. The only way to get accurate MPG figures, is to measure consumption over a given distance. I use an app to work out my FL1 MPG, and our family Ford Kuga. The Kuga's OSD shows a variation of some 10%, over the real consumption figures obtained via an app, over the last 48K miles. The only way to get reliable and repeatable figures, is to do it manually, or with an app.
