Codes P0011 and P0010?
 

Hi fellas,

I have a 2005 A4 1.8T with 60k on it. The check engine light comes on for 3 days or so then turns off for a week/ days. It'll come on, go off... come on go off. The codes I'm getting are P0011 and P0010. The car runs fine and haven't noticed any difference in gas mileage. What could be the cause and Problem solver to my... problem. Thanks in advance!

Mike
