P0171 P0174

[bakersx5]

Good evening X5'rs. I traveled from south carolina to dayton ohio for thanksgiving to see family. trip was fine the whole way. After being here a day my SES light came on. Local Advance Auto checked and gave me P0171 and P0174 codes. I have searched the forums and found a lot of info but my X is running fine. Mileage is good. I got 23-24 driving up here. Before I give the BMW "stealer" $100 bucks to tell me what it is...any ideas. It is a 3.0i. Most of the posts said folks were having problems with the same codes...HELP. I am 600 miles from home and i dont want to drive back after thanksgiving with the light on
