So my S-type has just started randomly asking for the system pin everytime I start the car? (it was standing for 3-4 days before)
 
	Once entered the radio etc all works fine.
 
	Is this a sign of a new battery being required? Or is this a sign of the usual dreaded S-Type elctrical gremlins?
 
	I've not checked the voltage yet.
 
	Thanks,
