I would suggest you check injectors and turbocharger, rather then DPF or EGR. These two will get you in limp mode if they fail (limited to 3000 rpms), but the car would still run, very slow, but not angaroo style
And because of this i am thinking injectors, or maybe a loose/broken hose somewhere.
My guess would be that mechanics did not do a good job on your car.
Like i told you any work on turbocharger => recalibration on ECU
any work on injectors => recalibration on ECU
These are done using ford diagnostic tool IDS, or specific tools, but they have to be done no matter what.
Things you can also check alone :
Turbo pressure : Have some one accelerate the car from idle to like 2500 rpms. Mean while just press the rubber hose coming just after the turbo, and see if you feel the pressure increase. This should happen starting on 1750 rpms.
Turbo fan : take the hose that goes from air filter to tubo aside, and you will see the fan inside the turbo, you a screwdriver or something to try and see if it moves up and down, if it does it is bad.
Hoses : Take the plastic cover off the engine. You will see that the hose has another smaller hose attached. Check if the clips are ok, usualy they have a tendancy to break, also from poor engnieering.
Injectors : while you have your cover off, look at the injectors, make sure there are no oil spills near them.
All in all, visual checks, i would not recomend doing something to the tubo, or injectors as a diy job.
EGR can be cleaned no problem, it's just had getting it out or in again, but anything else, i would not recomend unless you know what you are doing.
Hope you get it fixed, because from my pased experiences i can tell you that it was something small, and you usualy don't think abut things like that
