Engine Died While Driving HELP
 

Hello,
Son's car 2002 A6 Quatro 2.7T. Been Starting, idling fine and running fine. Just the other day about 40 miles into a drive, car died. He pulled over to side of the road and waited a few minutes, car started up and drove 5 more miles home. Have not driven since but starts right up. Codes turned up:
P0103
P0172
P0175
Approx 160,000 miles.
Anyone have suggestion on where to look or what section of this forum to search or ask?
Thanks,
Doug

Based on the codes it sounds like a bad mass airflow sensor.
