P0299 error on 1.6petrol ecoboost

[Inga]

Hi everyone. I have a slight issue with my  2012 1.6l petrol ecoboost. A couple of weeks ago the turbo disappeared. I can hear how it works, just no power. The code P0299 came out, we deleted it and I drove the car for a week as normal and it appeared again. The Engine service Now comes on a dashboard only when I rev it hard. So I already know thats turbo underboost, and that one of these parts might be related to it. Dont you mind sharing your knowledge to choose the culprit:

1)Barometric Sensor

2)Turbo pressure converter valve

3) Turbo boost pressures control valve

We have checked the wires and there is no sound of escaping air before ir gets into turbine...
