Excess crank pressure
My 2007 D5 consumes oil alarmingly. No oil leaks whatsoever. Taking off the oil filler cap on tick over is like opening a shaken bottle of coke! Same if pull out the dip stick too. Have been getting blocked DPF and am told by dpf guy that this is the route cause of the problem, excess crank breathing pressure forcing oil into induction system, causing vehicle to smoke and choking up DPF.
So what can cause the pressure?
