my update is that just today the dealer found a 'checksum' fault code in the DME and is awaiting BMW NA approval to replace the DME
while my messages have been ‘engine malfunction reduced power’ and (after the software upgrade) ‘drivetrain - maximum drivetrain output not possible’
your ‘fuel system malfunction – maximum engine output not possible’ is not all that different
