a4 turbo problem? help!?
Ok so recently I had no boost at all, major boost leaks. Fixed those and everything was great! Hitting tops of 19 psi. Then the car started to do like a hesitation whenever it would boost over 10 psi and would not accelerate until you let off the gas and depress the petal much slower keeping the boost under ten psi. Also there is a rattle when ever you depress the clutch from the turbo. Is my turbo going? Any questions please ask. Thanks for you help!

Sounds like you're misfiring. Does the CEL flash? You'll want to get the car scanned for codes to help point you in the right direction.
It doesn't sound like a bad turbo to me, but if you're curious about the health of your turbo, take the intake apart, remove the turbo inlet pipe and poke around in the compressor housing. Wiggle the CHRA around, feel the fins on the compressor wheel. If you see any oil in the charge pipes or compressor housing its a good bet your turbo is toast. A bad turbo will start to sound like a dentist drill when it spools up and/or leak oil/coolant into the intake/exhaust.

Yes the check engine light will flash a few times and stay on off a bit and then go out. But there is some oil in the inlet pipe. Ill have to poke around more and see. So if misfiring is the issue what my next step. Also dealer is the only one that can run the codes right?

could be few things, over boost sensor or knock sensor complaining, or misfire
no idea on the nosies but you say when you depress the clutch from the turbo? no clutch is present on the turbo unless you mean after boost on gear change?
would say your clutch release bearing is on its way out
