Landrover 300TDi(non EGR), Discovery 300TDi(non EGR) and V8 MFi model years 1996 to 1999 are suffering problems with the security system 'spider' ECU located within the passenger compartment. This system communicates with the vehicle Theft Alarm Unit and enables power to the starter solenoid, fuel pump and ignition coil (V8 MFi) or starter solenoid and fuel cut off solenoid (300TDi). The 'spider' ECU is a small rectangular black plastic box with 10 pin connector and is mounted behind a steel plate underneath the radio. Access requires removal of the entire dashboard!
