Slight judder when idle (Brera 2.4 jtdm)

I seem to have a slight engine judder when the car is idling.

I also think, though can't be sure without driving someone else's car to compare, that I seem to be lacking torque higher up the gears. I hear how great the torque is supposed to be, so am often surprised in 3rd or 4th when I put my foot down that nothing much happens...

Any wild guesses as to a solution?

EGR valve was changed recently and the DPF has been through a regen.

Mine used to run very unevenly on idle, almost so uneven it sounded like a galloping horse!!

I followed the advice of Gus, Alfatuner, and ran the car down until the low fuel light came on and the put a whole bottle of Wynns Diesel Injector Cleaner in and took it for an hours varied run, and it sorted it out for me.
Maybe had a slightly clogged injector and the concentrated dose cleared it out.

Other than that, could it be a leaking / cracked / loose pipe in the induction system?
