Trouble with Check Engine Light Code P0299

I've been trying to solve a check engine light code I've had for almost 6 months now, code P0299 (Underboost). There has been no problem driving the car, and I have been making about 15 lbs of boost. I took that value from block 115, the actual boost pressure and the specified boost pressure. Recently, I've replaced the diverter valve from a revision d to a revision d and cleared the code. 2 days later the code came back. I've begun to think that it might be the charged air pressure sensor. Does anyone know the Vag-Com block to read this sensor or have any advice, and if block 115 is the correct place to find boost pressure?
Thank you in advance
