Buzzing boost control solenoid

[Nathan300]

Hi to all

Randomly ive been hearing this buzzing noise from my boost control solenoid that is mounted on the side of the engine block . The noise can be heared upon accelarating, engine load or idle engine. 

Everything else is fine, with great turbo boost and accelaration. My only concern is this buzzing noise . 

I have read in many forums that buzzing noise is normal from boost solenoids, but i highly doubt it . 

I allready bought 2 of this selonoids, all of them from toyota agents, but all had the same results . 

Any feedback will be greatly appreciated

Hello and welcome to the LOC.

As you mention solenoids by their nature can buzz when active due to the coil being energised, it may be an idea to make  sure it is fully pulled in and there isn't something connected to it that is preventing this like a sticky actuator arm.

Thanks for the speedy reply . The solenoid is new . It has only 1 year from purchase .
