My EGR cooler was leaking coolant from the welds that appeared to crack so I replaced it at the same time. My coolant temperature is around 180-190F if I recall correctly checking with my Carly app.

I see... that's super weird. I have my egr cooler completely blocked off, disconnected and coolant lines blocked off in my x5 35d, all stock btw, and I don't have any codes about that.
I also wonder if the egr EUV being bad has anything to do with the cooling performance of the egr cooler. |
Is your car tuned for the delete? If so that's probably why you don't get fault codes.
I have a brand new intake manifold on its way. I'm going to carbon clean the valves, replaced EGR valve and the intake manifold and see what direction it leads me after.
