Why is my Audi A6 running lean?

I have a Audi A6 1.8T Quattro. The engine light is on, and I had it put on a computer which says it's got a air leak on the intake causing it to run lean. Two people have checked all the hoses on the intake manifold and they're ok. What else could be causing this?

Air is getting into the fuel system somewhere where it shouldn't be. Keep looking.
