DPF has no impact on the contamination IF the correct (DPF compatible oil) is used and it does not get ruined by failed re-gens, in fact, it should last longer as the modern engines have better combustion and hence less soot
A friend of mine is looking at an XE with the Ingenium(sp?) 180 diesel lump. She's seen in the press that they got some stick for diesel contamination in the engine oil due to failed DPF regens, do you happen to know how wide spread this is or if there's been any update to the car/software to address the issue?
My take on it was that as 50% of her journeys (and about 90% of total miles driven) are 85mile each way motorway trips, the car ought to be able to regen as much/often as it wants to.
Another oppsing long oppsing detailed description, and the useless oppsing wifi in this oppsing place lost it.
Briefly, ignore the cancer of facebook or lazy "professional" jounralists. Its only the D8 platform that appear to be impacted, due to the fact the D8's packaging means passive regens are not possible, so relies on more active regens. Interrupt an active regen, you get contamination.
Not sure if XE is D8, I think its related, but might not suffer the packaging problem, that may only exist on the Tonka Toys.
But journos are inherently lazy, so will say all 2.0d JLR engines, because they don't understand how shit works.
