Default 2014 A3 (8V) 1.8TFSI EPC Turbo problems?

Hi All, PLEASE HELP!

I am in need of some SERIOUS advise. I've taken my car to a number or garages and nobody seems to know what the problem is with my car. The last mechanic seemed to think its an electrical issue and told me to go see a auto electrician but I'm not convinced.

DESCRIPTION:
When I turn the ignition (sometimes I have to turn the car on for it to happen) I hear a mechanical grating noise which after inspecting the logs seems to be the Turbo actuator. After turning the car on and hearing this noise the EPC light comes on and the car doesn't hold boost properly (or is in limp mode). Sometimes, specifically when the car is warm the startup noise doesnt occur and the car runs fine for a minute or two then at about 1600rpm I hear some resistance and the EPC light comes back and the car is again in limp mode.

QUESTION:

It is possible that there is a problem elsewhere in the car that is affecting the turbo actuator? Such as a bad lambda sensor (o2) or a clogged catalytic converter.
Please note I am not a mechanic just another poor man with a broken Audi :P
Thanks in advance
