2010 A4 P2015 not the intake manifold

[Abu_boost]

My p2015 code came up and I figured it was the intake manifold so I went forward and changed it. It was fine for a few days then it came back on. If I clear the code then drive it is fine until I slam the gas pedal, then the code comes back. I figured it may have been a faulty intake manifold so I changed it again but the problem is still there. What else could be causing the code? The car also throws misfires at idle but it has had that issue for quiet some time before this code came up.

This might be it, flap motor or sensor.

Isn't that attached to the intake manifold? I replaced the entire manifold

Maybe but here's another existing thread on these issues.
