Well, since picking my 07 td4 auto last Saturday it's been avg. 26.3
Surely thats not right ? I was expecting around 30.
It's done 138000 miles with full history. I'm going to fit an egr delete plate this Saturday so that may help a little.
What do you think ?
 
Mine does about 33 normally, but better on a long run.
Makes no sense but it seems better in summer when the air is warmer and less dense, once managed over 40 on a hot day driving up to Scotland and taking it steady.
 
Pretty poor figures.

Can you not drop an L Series in an F2 to improve things?

Maybe replace that techno problematic transmission with a simple viscous coupling, and is all that fancy electronics really required? Could do with some styling that's a bit more 'interesting' to. :rolleyes:
 
No help to the OP. But my FL1 TD4 auto does 27 Mpg in the winter, climbing to 30 Mpg in the summer. All Cornish B roads on my 9 miles daily commute.
 
Seem low to me. Must be your driving style :D

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.

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.
 
Couldn't wait for Saturday, fitted it today.
Took it for a little drive and it feels slightly better, pulls away with more urgency plus my mpg started to go up !!
Happy days.
 
Keep us posted after a longer trial - I have the blanking plate in stock but still familiarising myself with a base-line performance before I start tweaking - currently getting 28ish with mixed driving (2010 F2 TD4) - and I was surprised to only get the same on a motorway run at 70/74mph - I thought with the high torque/high gearing it would have been better - my F1(2005 TD4) does 35/37 on the same run same speeds.
 
I'm surprised at these sub-30 mpg figures. I've got to thrash my 2007, no DPF fitted, EGR blanked FL2 to get <30mpg
Cruise control on the motorway at a steady 70mph gives me mid to high 30's easy.
Perhaps I've got a light foot. :rolleyes:

Or perhaps there's a wide variation in the way different FL2s calculate mpg?
 
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.
 
I always fully fill my tank and log the mpg - my figures on my F1 are done thus - the figures on the F2 are off the computer but the first coupla fills seem similar - time will tell. They are both Autos by the way.
If I kick down the F2 hard at 60ish I can kick out a brief cloud of black smoke in the face of a tailgater I noticed last time out.

I agree. I've done a few 'tank fills and measured miles' on long distance runs and find the on-board computer to be within a couple of mpg of my own calcs. I might try it for general running around to see if there's a wider discrepancy. One thing is clear though, the on-board computer calculated mpg is repeatable and clearly shows the benefit of premium grade fuel.
 
I was always pleased with performance on the td4 160, but disappointed with mpg, sd4 190 was quicker and more frugal, both 6spd auto
 
What the hell the blank only cost a few quid worth a try, so ordered and fitted it.
Mpg jumped up immediately and today I drove about 75 miles down the A1 and recorded 42mpg (on board computer) I have a feeling the EGR valve must have been passing exhaust gas all the time and stifeling the engine. I want to add some injector cleaner and give it a good fetteling to try and get all that muck out.
In spring I may clean out the manifold and have a look at the EGR valve.
 
After a few days of travelling to work and back and no improvement. Work so far....
egr blank and h2o carbon clean. Gauge is moving between 26.7 to 27 mpg. That's driving it sensible.
I know it's unlikely but could a faulty crank sensor cause poor economy? Only I did a scan and it showed crankshaft sensor but the car starts and runs fine. ???
 
Well, something strange happened today.
Yesterday I put a can of wynnes inlet cleaner through the car out of desperation. I went to the garage this morning to fill up and take it for a run. As I pulled away I noticed the computer was climbing!! Anyway, I did the drive ( approx 28 miles ) and by the time I got home it had climbed to 36 mpg ???
Very strange but I'm pleased. Let's hope it lasts :):):)
