It needs further investigation by someone who understands basic faultfinding procedures and has decent diagnostic tools.
I wouldn't waste your time changing parts until it's been established if you have one or more underlying faults.
ElsaWIN suggests there's a procedure for checking the actuator, which involves fitting a new link and confirming the turbo actuator is free and moves to where it's supposed to based on electrical signals received from the control unit.
This thread looks very similar in terms of symptoms and fault codes

It needs to go to a proper VAG specialist with the necessary tools - the VAG tool for testing the control unit is 'Tester for E-positioner -VAS 6395-'
