I can get your PIN if you give me your VIN.
I work for Holden.
Your car is a blue hatch, PIN should be 0105, if head unit is still the same as records show.
Hope this helps you.
Glad is it the right number for you, keep a written record in a safe place for whenever you may need it again.
I hope to offer you any further advice for your Astra in the future.
All the best.
