Thx colin, Anton the master technician, swears that all 370z have a steering lock, he said it could be sticking on 1 of the 2 pins that lock it, hence the fault, i did mention why there are no lights on the fobgina, said it could be part of the same fault
yeah car drives perfectly every time since the light came on, not paying £679.20 to just have the light turned off, the steering lock fuse as been back in just over a week as well and still it works apart from the damn yellow light on the dash.
