You probably need a software update which will cost you about £100 from a main dealer or quarter of that if you can find someone else to do it. Wherever you go, they might also want to charge you for the diagnostic test again (£50 at a main dealer, £20 or £30 elsewhere). Google for Vauxhall Astra Field Remedy 2115 for more information.

Before spending any money, try turning the ignition on and pressing the buttons to lock and unlock with the key in the ignition as this will reset some of the settings.
