Apparently there's a new SIB (SI B13 06 16) out there for the M57 that reads something like this: "Replace the hot film mass airflow sensor (HFM) because internal tolerances do not meet specification. Can cause a SES light."

I haven't seen it so I'm not sure if the codes would be the same you are experiencing. Like ard said the air intake temperature sensor is part of the MAF assembly (there's also a charged air temperature sensor in diesel engine which is different and placed on the charge air tube right before the throttle/EGR).

In any case, call your local dealer, reference the SIB I gave you, see if it applies to your car.

If you get a copy of the SIB share it, pls.
