"False air" being drawn in is a know cause of trouble.
Combined with the post-turbo loss, the ECU was simply being fooled about what amount of air and % EGR it had.

Ah, so the leak was between the sensor and the turbo? That would explain it.
My air sensor combo also has a metal screen, but only on one side (upstream of the sensor). I believe that the metal screen may be heated, but I'm not sure of this. I haven't noticed oil on it, but I haven't looked lately.

The valves' operating mechanism isn't really smartly designed, with plastic parts wearing out easily, affecting air and EGR.

I meant the
intercooler bypass valve (air doser, "butterfly double air metering device"). They come in different shapes and configurations, some only restrict the intake, others allow the IC to be partially or completely bypassed. Not sure which one you have? But the EGR comes in later, in the intake manifold, after the air doser. The way that the air doser can increase EGR flow is by partially restricting the intake (=lowering air pressure) before the EGR inlet.
Could you post a picture or 2 of your "naked" engine (
sans plastic covers), and maybe show which parts went bad? I don't suppose you have a picture of the cracks and holes in the replaced parts?

Don't worry, I probably won't get any chances to beat that again for a long time
