I don't know why you think everything can be resolved as easy as changing a sensor. That's not what codes are telling you. They merely describe a specific situation that has to be further diagnosed.

What engine does your truck have?
Is it an X Drive?

The P0012 and P0015 both have to do with the Vanos system on bank 1. They are for the camshafts being over retarded. The solenoid could be the issue but numerous other things could be also like the Vanos actuator or the timing chain. It needs to be checked out further. The P0100 is an issue with the Mass Air Flow sensor which could be the wiring, the computer or the sensor itself.

On the camshaft issue, make sure the engine is full of oil and the oil is the correct viscosity and clean as that system operates on oil pressure.

I would probably try clearing those codes first and see which ones come back just to make sure the MAF code wasn't set accidentally by someone unplugging it with the key on.
