Thank you folks.
Sorry, I only had access to the generic bluetooth code reader at the time I created the post.
I just ran it through INPA and BMW Scanner and those corroborate the "generic" codes from the bluetooth code reader :-).
I also neglected to mention that yesterday when the issue started (I had been driving on the interstate for a few hours), I could smell fuel in the cabin for a bit, so I am thinking the fuel mixture is too rich and therefore maybe a MAF problem?
Also, I just did the test suggested by @Effduration [disconnecting the electrical plug from the MAF while the engine is running] and the engine did seem to stabilize some, though not sure it fully stabilized. I did an audio recording of the test, I will post as soon as I figure out how to get it uploaded to youtube :-)
Next up going to try moving the coils around and see if the issue moves to other cylinders.
