What is the component near air filter in Astra G

Question

In my Opel Astra G selection 1.4 I found a blue plug connection, what might be its use?

It's near the air filter.

It's a solenoid which is used to provide vacuum to a component. There are usually two things I've seen it used for:

Exhaust Gas Recirculation (EGR) valve activation
EVAP canister activation

I don't know which it's used for in your vehicle. You'd have to track the lines in both directions and see where it leads to.
