SMOKING 1.6 HDI ENGINE

Can anyone help ?

Have a Citroen c3 1.6 hdi 95k on the clock, my problem it smokes badly on cold start up, runs fine when warm and no power loss.

Have taken it to several garages and the cost is mounting up, turbo replaced 3k ago, injectors tested one replaced, compression test all ok , all other tests completed. Oil,and filters replaced, engine flush even added stop smoke but nothing helps.....

Thanks in advance

Have done around 150 miles trip this week & still smokes when cold, have tried some motorway driving but nothing helps.

Smoke looks mainly white, there is no power loss.
