What is a N75 code?
My 01 A4 had an N75 code on the VAGcom last week, so I took it to the dealer, and they said they fixed it. But I'm still getting that code, and my car is still sluggish. What does that code mean and what could be the problem? thanks

N75 is the wastegate control solenoid...
... if it was giving you an error, the error code would be something like:
17956 - Boost Pressure Regulation Valve (N75): Open Circuit
Your car is slugish either because you are in limp mode due to overboosting because of a bad N75 or the N75 is not assisting in the boost regulation and you are only using charge pressure to control boost.
Either way, take it to the dealer and have them fix it. Make sure you leave the code in the ECU for them to find. Otherwise, look at the N75 valve itself... the electrical connection as well as the three vac lines on it.
