blocked air filter (cheapest option if it is the problem), EGR valve,worn injectors,faulty turbo....could be anything.

There is a Derv Injector product that will help to a point to clean the injector tips, the four outlets on the injector tip get cloged up, Put a bottle of this fluid into a full tank of derv & try £5.00 ( Cost) What is the milage? has the car been serviced & when?

Try what I have stated the Injector cleaner, other than that, a re/con set of Injectors. You may be able to get these localy, try your local yellow.
