On most newer cars the radio is coded to the engine management unit so you do not need to put in a code, I do not understand the bit about Vauxhall not starting if battery disconnected, I guess that is what you get for buying a Vauxhall.
My last Lexus had the light come on and the local garage said either take out the ecu fuse or disconnect battery for half hour, then the system is reset and if the light was being oversensative as they can be it stays off but if there is a problem a reset will not cure it so the light comes back on.
I did this half a dozen time on my Lexus as the light kept coming back on and the fault code was take to main dealer, this is very EXPENSIVE with Lexus main dealer so in the end i part exd for another Lexus that touch wood the light stays off on this one. lovely cars but main dealers know how to charge.
