Unlikely it's the battery if it's new. Just offering that as the symptoms described could be caused by it. I'd still rule it out.

Otherwise, could be the MAF as you said, or a throttle position sensor.

I'd also try to code reader again. Your buddy's reader isn't just generic ODBII, right, it's a full BMW scanner (like Bavarian Technic, P.A. Soft, etc.), correct? Not all codes that are BMW specific are read by all readers.
