Nothing to add, but that is some top lurking!

Did it smoke before lots of things were changed?

Were the rings changed?

What are the injectors like ? Maybe they are a bit shagged and can't handle the extra 'ooommmpff' ?

they seen to be ok starts runs drives spot on

Might it be something to do with the dpf delete and the decat?

[colindaniel]

piston rings have never been changed to my knowledge

i did take the inter cooler pipe of turbo when ticking over and u can se small amount of oil creping up from the turbo

[mmm-five]

Ive yet to see a BMW diesel that has been mapped not smoke from the moment after remapping no matter what mileage or age is on the car it was never built to handle all the extra boost these maps put through the car assuming its not just extra unburnt fuel that the map is using to try and keep everything cool could also be DPF delete not catching all the soot/oil anymore or EGR or swirl flaps but we dont know what model age year your car is but its probably just fooked
