The injector tips are greased, which would result in some combustibles in the chamber. I'm suspecting that.

Tech drove it two miles. Still not enough to get the temps up.


As for why the DPF didn't harvest it, that's an interesting question. They don't function perfectly when cold, and if there's an excessive smoke event, it could just be passing through as the honeycomb isn't warm. I also can't say whether the car was in a regen, as that would potentially result in a downstream application point of raw diesel on the element. Those are generally back pressure triggered on our apparatus power plants, but not sure if it's the same on the BMW.


There's no trigger event for a turbo to bite it, no symptoms prior to the fuel pump issue, etc. so I just don't see how the turbos could have failed simultaneously when there's no oil pressure problem, no early turbo lag issues, no prior smoke or odor, etc. if someone with an E70 or a 335D has a story, I'm all ears.
