    2009 audi a4 p2779 code

    Hello,
    I have a 2009 Audi A4 quattro. I just had a high pressure fuel pump put in a couple weeks ago. Check engine light came back on yesterday with the p2779 intake air leak code. Car is running fine, no rough idle or anything. Any ideas on what it can be? I'm at a loss since the car is running fine.
