It's not burning before the turbo (outside the cylinders). It's burning in the dpf. Along with the trapped soot (carbon).

Ok. So the egt temp is the leftover heat from combustion, raw fuel is mixed with it and the stream cools as it enters the cat. The mixture is then relit when it hits the dpf. Makes more sense now. Thank you.

I have done two consecutive Oil Samples with BlackStone Labs and my fuel dilution measured less than o.5% on both occasions. The Last report on my 2012 CRKA Passat was with 12,600 miles between changes and it had no additions or loss of oil between changes and viscosity was within tolerance. Of course, just about everyone has some Bio-Diesel in the mix. It is EPA.

THIS. This is the way to KNOW -not speculate- what the oil's condition is. And it's highly specific, because it says what the oil's condition is for THAT car, driven in THOSE driving conditions, and in the driving style of THAT driver.
Great post.
