My Ride: 2008 535i
Fellow 535i drivers!
I have a 2010 535i with 31k miles on it.
I JUST had the 30FC and 2AAF codes last week, along with engine malfunction power reduced message on IDrive. This occurred during WOT and cleared after restart. No shaking or misfiring that I could tell.
These symptoms sound a lot like some of yours.
So I take it to the dealership (I have original warranty left) and they fix it the same day. They replaced the Low pressure fuel sensor (LPFP) to fix the 2AAF code. The Tech notes state that the LPFP was measuring incorrectly.
They replaced both Pressure Converters (I think they're also known as Wastegate solenoids?) to fix the 30FC code. They detected a reduction in vacuum pressure I believe. The Tech wrote extensive notes on the work order so I'll post that up when I get back from work today. He conducted several pressure tests using a pressure gauge and vacuum machine. I was impressed with the process he used to find the problem.
After the fix, I get no more Check Engine Light or IDrive messages. Also the car definitely feels more powerful.

I had a similar issue two different times. The first time was a vacuum line on the turbo and the second time was the low press fuel sensor. Both felt the same to me, but there were different codes.
