Hello,

Hight pitched noise from the Idle air control valve happens due to an internal leak.
This leak is in the valve system itself and the IAC will need to be replaced.

Since the Astra was not sold in the US, we do not have access to the repair manual of this vehicle.
The IAC is located on the throttle body and is mounted by 2 screws.

Here are a couple of helpful guides on IAC:

Please let me know if you have any questions.
Thank you.
