Not seen or heard the issue before but there is a bulletin from Toyota that may be the cause:

EG-0030T-0317

Subject: Noise from the vacuum regulating valve

Models: AURIS; C-HR

Model codes: NRE185; NGX10; NGX50

DESCRIPTION OF PHENOMENON: Some customers may experience and report noise coming from the engine compartment. The noise is coming from the Vacuum Regulating Valve. In some occasions the following DTC is stored in the ECU: DTC P024313 Turbocharger wastegate solenoid “A” circuit open.

SYSTEM DESCRIPTION: An efficient single-scroll turbocharger is used to achieve high torque from low to high engine speeds. A wastegate valve is used in the turbocharger sub-assembly. When the vehicle is being driven at low load (turbocharging not necessary), the wastegate valve opens to decrease the back pressure and reduce pumping losses during the exhaust stroke. Also, the wastegate valve opens during start-up to decrease the amount of time needed for the catalyst to warm up. The wastegate valve is closed during higher engine loads.

REPAIR PROCEDURE: Replace the “Valve assy, vacuum regulating” according to the procedure in the repair manual.

If the issue is a per the bulletin above then no its just an unusual noise that can be fixed with a new valve
