What happens...
when DPF is reasonably clogged but still operative and everytime regeneration is activated engine oil is diluted with diesel becomes thinner and thinner and thinner. It goes through the piston rings and especially turbo seals to the engine combustion chambers and burns. When that oil burns DPF clogs much quicker hence you all guys have a message - DPF is Full.
DPF issues is the first reason of the turbo seals failure.
Even DPF is not full, it gets regenerated randomly and you change engine oil within intervals but still have high oil consumption - suspect turbo.
1st step - sort out DPF untill its not too late

My turbo is brand new, dpf claened, 2 liters of oil in 500miles, cannot see that it can be related to dpf,
also cannot see that there is any connection from DPF/CAT to oil system for this magical dilution of oil that I have seen, perhaps this is only in the newer version....
going to try a compression test, wet and dry....
