that is your barometric pressure sensor, it measures ambient pressures to adjust the fuel trim according to climate and ambient conditions. the MAP sensor only measures intake vacuum and pressures.

Atmospheric pressure sensor. If you live at an altitude like say, 750ft, and you disconnect it, it (ECU) will defaut to zero altitude and the AFR's will read noticably richer. Been there, done that.

S4 cars only.
