Fault Code issues, help?

Still going soft limp at random times, seems like only at half throttle, I thought it was the DV, changed it out to the stock one, same thing. Here are my codes!

17965-Charge Pressure Control: Positive Deviation P1557

17705-Pressure Drop between Turbo and Throttle Valve P1297

Any ideas what to do next?

Okay, I checked my eBahn reader

To start off.
Code 17965: Check N75 Valve operation

Next

Code 17705: this will be more difficult because of more leakage points.

eBahn says to check the Connection of charge throttle valve. Therefore check the hoses BTWN Turbo and Throttle Valve. You will check the pressure drop using VAG tool 1687. I think Steve(ModshackTT) might have a similar tool. Good luck. If you have any more specific questions like specifics. let me know. What year and engine you running. AMU ?
