2012 Cayenne Turbo, 209K miles. Stock Prosche parts and tuning. 

 

Durametric reads these codes, if driving around city streets not in sports mode. 

P1071 Mass air flow at idle speed implausibly high (fast deviation)

 

P0068 Mass air flow implausible. Value below lower limit value

 

These codes seem contradictory. 

 

Seems to idles and perform perfectly, and the auto shut of feature, activated with brake on a stop lights, also works as before.

 

Air filters are new as is the MAP (Manifold Absolute Pressure Sensor). Wires seem securely attached. 

 

This is baffling.  Any thoughts or direction?
