Glad to hear you have sorted it.
This is the problem with your age of Disco. The pinouts cover all Disco
300 tdis but if your disco is before the 95-96 change then you need to use the 4 pin blue plug to diagnose the ABS with. As a rule of thumb if the alarm fob has two buttons on it then you can use the OBD II socket.....But as always with Landrover nothing is ever certain.Good luck.
