Maybe the EGR needs cleaning through too.
Try some BG244 in your fuel, it's about £19 a can off eBay but does exactly what it says on the tin.
You could check silly little things too, tyre pressure and wheel alignment can make a car feel sluggish as well.

What springs to mind is the car driven in the same way as before in the same conditions?
Has the car got the same amount of weight in it?
As others have said, tyre pressures, brakes binding, can cause lack of performance/ economy
the car has a DMF, when its on its way out you can loose performance
Deisels can take ages to warm up and longer in cold conditions and often drive like a "bucket of bolts" when cold
problems with the thermostat / coolant system often do not show up in fault codes, because the ECU percieves that as the (extended) warm- up phase
deisels are less efficient untill they are warmed up, the most efficient temp for economy is 195F
on top of this the temp gauge is "docktored" by Ford on many models (to read wrong) because of punters thinking/ complaining the temp was reading too high or low
As others on the forum have said, the CAT can get blocked up, especially if the car is driven gently too much or is producing a lot of smoke
The EGR valve can choke up the valve housing and the inlet manifold with carbon deposits/ gunge, this is even if it is working "perfectly" with no fault codes etc
Cleaning the inlet manifold / EGR housing of carbon/ gunge is not part of the service shedule (although it shpuld be) and in my opinion, EGR valves/ systems should not/ have never been fitted to diesel engines, (EGR means Exhaust Gas Recirculation)
If you fit a solid, stainless steel EGR blanking plate (you can pick one up online for about a fiver) (there are "how toos" elswhere on the forum) and clean out your inlet manifold that may bring the car back to how it was
Without the EGR (with the egr blanked) it may run "cleaner/ less smokey" - so that when you "boot" it, it helps to clear out/ unblock the CAT, if the CAT stays blocked, the answer is to fit a decat
Finally, how do you drive the car?, if you change up too early or too late, the engine won't be on its operating range/ powerband - i have to ask, sometimes it sounds like members only use 2 gears, 1st and top, and then complain the car is sluggish,exept they don' explain its when going uphill in top gear at 30mph!

good point Foca. when i drive my car i notice that its very sluggish in 4th at 30mph so drive it on 3rd at 30mph and in 4th if doing above 35mph and wont go into 5th until i am doing 50mph.
if your CAT is blocked then get it decatted as this will make a big difference.
for the EGR, i have created a guide on here on how to add the blank - 20 mins to do.

Hard to tell from the video, but it sounds a bit "tappety" ie - valve train/ top end wear/ engine wear
Was it ever run dry of oil/ not had an oil change for a long time or is ever thrashed from cold?
like i said its hard to tell and otherwise sounds healthy - and these engines can be noisy/ rattly

its never run dry, i just bought it last year and its just had another service.
just seems noisy compared to when i got the car feels like an old taxi cab lol
i think im going to sell since im unhappy driving it now, need to get it valued.

Ok so im going to try and get a garage or mobile mechanic to check the engine noise and see what they think, can anyone recommend me anyone near rosyth,fife.
