that is poor. we have a 2.0tddi mondeo and on a 160 mile round trip to the coast today the computer reckoned an average of 55mpg. never had it below 42mpg and that was round town for  a week with no longer runs.

i try and change gear below 2000 rpm unless i have to "boot it" for any reason.

I also suspect  that 34mpg is well below par.

As previously mentioned, of course it depends on your driving habits.

Unfortunately, unlike on older diesel engines, with yours there ARE NO ADJUSTMENTS YOU CAN MAKE. Everything is software controlled.  So all you can do is take it to somewhere that has the computer device that plugs into the cars engine management system and have the data checked.

A main dealer will probably want to charge around £80 for this service, but look around for a local engine tuning place who will probably do it a lot cheaper.

Given cold starts, short runs, town driving, then I would suggest 34mpg is acceptable.

You see what the fuel consumption is during a long run though.  You should then get around 45-50mpg.  Then you know for certain.

 Hi Kev, had a 03 1.9dci and only travelled 2 miles to work a day. Fuel consumption was poor around 35mpg. However taking it on a long run on motorways etc. and driving as smoothly as I could I managed 54mpg according to the computer.

Now got a Terrano ll and thats a different story!!
