Blue Smoke

Hi guys,
Hope you can help me with a problem that has been bugging me for a while on the audi A4 2.0 tdi 55 plate blb engine code.
Ive been getting a small amount of white smoke on cold startup and large amounts of black/grey smoke on aceleration, The car also has a bit of vibration in the seats...like a small judder at idle, idle's fine btw and does not miss and is not rough.
It doesnt smoke when cruising it smokes after slowing down and pulling away again.
Noticed its all or nothing on the turbo on pulling away, it will accelerate slowly until about 2000 rpm then whacks you back in the seat as turbo kicks in or is that normal?
Check emission light came on and vag reader said it was faulty MAF, code P0101 and cylinder 4 glow plug circuit p0674
We replaced the maf but still smoked exactly the samee and after 80 miles check emission light is back on with fault P0101 and im not sure where to turn next, Clean EGR valve maybe?
Want to add that there is a rattle from the engine but it is the aircon clutch so have ruled out DMF for the engine vibration/shudder.
Just worried it could be something serious and want to get it fixed before it got worse/ruined something.
Many thanks for looking and any help is greatly appreciated.
EDIT: Forgot to add it has just had a full service so all filters are new.
