Clean out the oil pick-up in the sump before it kills your engine

 DPF Dirty Oil Pickup This is what it looks like
when the oil pick up is blocked and kills your engine.
Clean Oil Pickup This is a nice new one.

This happens when the oil gets polluted from bad diesel when cleaning the DPF.
It can also happen if you use the wrong engine oil.
Remember to check and clean it once in a while.
