Trouble codes

My check engine light went on last night. Just checked the DTC and got the following code P1416. The description is Air System Bank 2-B. What does this mean and what would cause this? The only mods I made was a Black Wing and Corsa exhaust over a year ago. Everything has been fine until last night. I have a 2003 A4 Coupe with 45k miles.

Thanks in advance

it means that the check valve probably took a dump.it also happens to be the one that you have to pull the intake to get to.other possibility is the hose in back being off,but highly unlikely.
