Had a warning come up and say "Comms Fault" the my command control screen went blank but radio was still working and could change the channels on it but nothing else.... so pulled over shut off car went to restart and then it stalled and warning came up and said vehicle immobilized and then said Comms Fault again after.... tried my other set of keys and car started and was fine but then went to start it again this eve with the keys that were allowing me to drive and the warning came up and said vehicle immobilized so shut it off locked the car unlocked it again then the car started with no worries or warnings now seems I have to do this each time I try and start car does anyone have any ideas on the cause of this.... Many Thks :)
