Hi, my Vogue SE has an ABS/TC fault, the blink code comes back with code 2-3 which apparently does not exist! However working with the assumption that its the same as the early P38 ABS system this would point to the pressure switch, so I acquired a P38 ABS pump and took the pressure switch from that and fitted it but there seems to be no difference, is there any realistic way to test the switch? the pump runs and shuts down when pressure is reached with both pressure switches
