Valve stem seals need replacing
Turbo needs to be rebuild
Blown head gasket
Cracked head

One possibility..........and the least costly............is a bad glow plug on #6. The blue smoke is typical of a stone cold cylinder with no glow plug assist.
However, I'm not sure of this because it should clear up within about three minutes...........not 15 minutes.
You don't have a bad turbo or bad valve stem seals.
Does the engine consume any coolant on a regular basis?
Is the upper radiator hose very stiff the following morning after the vehicle was shut down? If you release the cap on the expansion tank, does this stiffness in the hose disappear?
