I got same error messages. Modded and tuned also.
Turns out it was the in-tank low pressure fuel pump and/or the EKPS unit that controls that pump. They're usually replaced together.

Had both replaced and all is well again.

You may also notice a lot of white smoke coming out of the tailpipes like I did.

Its happened to me twice. 1st time MAF, 2nd time, injector. There seems to be several factors that can cause this, but they all seem fixable.

My E70 X5M has a recall for the intank fuel pump, hopefully you guys do or will soon have the same. I found out by running my VIN on BMW's website.
