I'll be dropping the car off tomorrow, not sure how much detail I'll get from the dealer on this. I went to take a very casual look this weekend (pouring rain and didn't feel like really getting dirty, anyway) using my phone camera and I just couldn't see anything obvious. I started the car up and let it idle while I listened around that area and all I can say is holy crap it was loud. It's coming from either that flange area or like the turbo. I doubt it's the turbo, but then again, would a leak in the EGR cooler really throw the engine malfunction code?
