Dont know if you still suffering from this but thought I would let you know about a strange resolution to my smoky JTD
Mines always been quite smoky and every 6 months or so I strip the EGR valve and clean it all out and while am on I give the MAP sensor a clean, make it a bit better but still smoky under boost! Had her remapped not too long after purchase and always thought this was to do with the map!
Always looks worse in the winter months as cars behind headlights highlighted the smoke on the dark nights
Well the other day I started getting a whooshing noise from under the car on boost! I guessed this was the lower turbo pipe and ordered one. Order a nice black silicon one! Fitted it and the whooshing noise and the massive amount of black smoke assorted with the hole gone!
The main thing is the on boost cloud I got has also gone, as has a slight hesitation just before the boost came in. Now thinking that the pipe may have been porous in some way (It did look goosed like! All soft and spongy)
I know you have replaced the bottom hose but what does the upper one look like? Could be that, just a thought
Just cause it smokes doesn't mean its broke
*Unless the smoking is due to a breakage, then it does
