Landrover Defender 300Tdi (1998) Immobiliser problem.
I am having problems starting the vehicle. Put the key in the ignition, and have to wait a while before the immobiliser will allow me to start the engine. Some times it will take several attempts to get it started. I have changed the battery in the fob, but this has not improved things. I believe there is a passive coil fitted around the ignition switch, I am thinking this could be faulty, is it possible to change this as a DIY job, or is it one of those jobs were you need the TestBook computer. Anyone else had this problem?
