2005 528i engine fault reduce power, OBDII P16A7 error

Hi all,
My friend 2005 BMW 528i keep getting this engine fault and reduce power once it has fully warm up at which point the car lost all power and the engine idle fluctuates wildly between 300 to 1500rpm. Turn off the ignition for a moment then restart with get it running again for 3/4 to a mile before engine fault re-appears. The OBD code reader show P16A7 along with P0102, P0113, P0131, P0304, P0313, ,P0411... these 'other' codes are not always show up but the P16A7 is always appear when the engine is in fault mode. He had changed the catalytic converters, O2 sensors and secondary air pump with no success.
I swap out the MAF with a good used one from another car but got no luck so we're stuck at this point.
Does anyone knows what error P16A7 is and what can we do to fix this issue?
Thanks in advance for your advice.

This might help (Google'd the error code): http://www.baltimore-bimmer.com/2012...16a7-e46-2004/

Different year, etc. but the same type of problem.

Here's another: http://community.cartalk.com/discuss...e-system-crash

Both articles refer to E46's but seem to be the same problem ... blocked exhaust or cats.

Let us know what you figure out.

van556, I have a BMW with the exact same problem you had, intermitting power loss, please advise what your fix was??? when driving, usually higher speeds, the car will just loose power and have no acceleration but will remain running. must pull over to shut the car off, when turned back on its fine for maybe a few hours the happens again. Pulled p16A7 code as well as PO411, any thoughts??
