buzzing sound under slight acceleration
I have a weird buzzing sound with slight acceleration . Once I accelerate completely it goes away. I remember my n54 having this issue and it was the boost solenoid. Does the n55 ewg have a wastegate actuator or boost solenoid?

The noise comes from the turbo side of the engine. My phone doesnt even pick up the noise.
