astra h - astra h refusing to start b1616 & b1614 - dougieboy

bought this car 6 weeks ago and I got 3 months warranty with the car, but for the last week or so the car has refused to start now and again(both on my key and the wifes key)..so got the above error codes and have been told its the cim module...I rang the dealer from where it was bought and he says its not covered in the warranty so will have to stump the cost myself? where do I stand on this as I say only had it 6 weeks, also have kids and dont want to be stranded in the middle of nowhere
