I just checked my E-46.  This is on the bottom of the car.  It points 
backward.  I don't know for sure what it senses but it may be an airflow 
sensor.

<< My wife went over a curb stop recently(really it was her) and damaged
 the lower front bumper and 2 shields in front of the wheels. My question
 is that when I pulled off the damaged left front shield( the plastic
 piece in front of the wheel well)a sensor fell down. It has a kind of
 needle shape about 1 and 1/2" long. Can anyone tell me what it is for
 and where it goes? I am assuming it was attached to the plastic
 somewhere but there is no clip or way to mount it. TIA >>
