SES Code 2761

Hey everyone. Just pulled this code from my '06 with 70k miles. Anyone know what the code could mean? Thanks for any help you guys can give!

No decrease in MPG noticed. No stuttering or stalling or anything. Engine seems to run fine. There is a noticeable 'whiff' noise a few seconds after I shut off the engine though. Like a release of air or something?

I think that is an airflow error. If so this might help:

Ok cool. I just got that print out from the 7 series forum so hopefully that will help me diagnose tonight when I get home. I hope its just a hose that fell off the pump...

Well our system looks nothing like the one in the BavAuto guide. I mean somewhat but there are a lot of hoses on that diagram that I dont have. I just have the one going from the pump to the canister then to the valve on the exhaust manifold. The pump turns on so I'm guessing it isnt the relay.
