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.

My 335d is tuned, but my x5 35d that I'm talking about is fully stock (no tune) with egr completely removed and it doesn't throw those codes. I'll attach a picture of my egr related codes. But that's why I'm wondering if maybe a bad EUV is causing the poor cooling performance.
I think I have a egr valve from my 335d still if your looking for one!
