Annoying NOISE from EVAP valve, CANISTER, PURGE , Mercedes B gasoline, but IT WORKS CORRECTLY

In this engine, the EVAP valve, when activated, makes that annoying noise, although after a few minutes it should normally deactivate and after a while it activates again and so on.

That noise is the EVAP purge solenoide, It is not the rockers as believed.
