Ok i recommend you give it a service yourself -
A pattern air filter could help with your lack of power and is easy to change and cheap (about £5 online)
An oil+ filter change is a good idea won't make a big difference power-wise but protects the engine from premature wear, engine may run sweeter/ rev just a little better
The fuel filter can get clogged, a fresh, genuine Ford or premium filter can really help, if you are doing it yourself if you fill the new filter up with diesel and have a second car with jump leads or a booster so the cars' battery does not go flat (you have to "turn the engine over" to bleed the system)
These are all "service" items so will need to be changed at some point anyway, so you can rule these things out. Fords recommended service intervals can be very long (too long IMO) and often some, of these things are not done at a "dealer" "service"
Servicing the car 1st may save you money "fixing" things you don't need to fix - garages love spending your money - injectors are favorites (nice and expensive!)
The other thing to do at this stage is blank the EGR valve with a solid (no holes to let gasses through - that type does work) stainless steel blanking plate. (about a fiver online)
The EGR valve sticking open could be what is wrong with your car - fitting a blanking plate may "fix" it, this is cheaper than replacing the EGR valve and the car will actually run better with the EGR blanked than a "perfectly" working EGR system, blanking the EGR will not cause the car to fail a 2013 UK MOT (it may help - less smoke) and the worst thing that can happen is the EML (engine management light) comes on on some (euro4/5, not ero3) engines
The inlet manifold can (read will) get contaminated with carbon from the EGR system (egr means exhaust gas recirculation - literally directing dirty exhaust gasses into the inlet) - taking the inlet manifold off to clean it out can help matters (i don't think this is what is wrong with you car though)
The other thing is to invest in a Haynes manual for the car, and aquire a code reader, a garage will charge you about £80
to have your cars' code read (each time) i have a code reader for sale for less than that that you use again and again
Hanes manuals are quite expensive now, but they can pay for themselves in the long run, sometimes you get conficting advice on forums, Fordpidia etc, the Haynes manual is often based on the original Ford workshop manual, so can be trusted to have the correct information at least 99.9% of the time (wont have info on blanking EGRs though, i dont think
nuff said for now
