If a diesel is clagged up enough to fail the emissions test then "taking it for a blast" is 20 or 30 miles of motoring at moderately high engine speeds, and then straight into the MOT bay while the engine is still piping hot hot hot!
If you've not done that type of mileage at at least 3000 rpm then the Italian tune up is unlikely ease things, assuming of course that is the problem.
