cutter Posted October 27, 2010 Share Posted October 27, 2010 I have a 97 disco 1,that started having problems akin to the imfamous spider problems so I bought the plug in bypass stripped of all those nasty bits of plastic only to find the spider had packed it's web and moved on. So what I was wondering is weather any of you electrical/security boffins could help me out the disco is a 300 tdi manual Quote Link to comment Share on other sites More sharing options...
Underdog Posted October 28, 2010 Share Posted October 28, 2010 Have you read this thread: Alarm Spider Thread and have you checked to ensure you don't have an EDC model???? Quote Link to comment Share on other sites More sharing options...
cutter Posted October 28, 2010 Author Share Posted October 28, 2010 Hi thanks for your answer, I have already checked out that brilliant "spider thread",A few months ago I had to replace the injection pump,the old pump had some electronics encased in plastic next to the stop soloniod, the one I replaced it with did not it ran perfectly well for at least 2 months,then started to get the tired spider symtoms,so I bypassed the spider or what I thought was the spider by connecting a wire from the ignition to the starter and putting a wire from the battery to a rocker switch then to the stop soloniod, this works but the starter motor overuns unless I switch the ignition off then back on again to position 2.then it runs perfectly because the mot is due Ineed to sort it. There is an ecu in the drivers footwell with diesel control unit wrote on it could this be at fault. ANY IDEAS WOULD BE REGARDED AS A LANDY SAVOUR REGARDS STEVE Quote Link to comment Share on other sites More sharing options...
BogMonster Posted October 28, 2010 Share Posted October 28, 2010 If has has an ECU with diesel control unit on then methinks it is an EDC engine... Quote Link to comment Share on other sites More sharing options...

BogMonster Posted October 28, 2010 Share Posted October 28, 2010 I think EDC immobilisation is built into the diesel control unit - but mercifully we don't have many of them here so I don't know for sure. Quote Link to comment Share on other sites More sharing options...
cutter Posted October 29, 2010 Author Share Posted October 29, 2010 If I find the source of the problem and an answer I will let you all know. very best regards Steve Quote Link to comment Share on other sites More sharing options...
Ally V8 Posted October 29, 2010 Share Posted October 29, 2010 If your original pump had the enclosed unit with 2 shear head bolts holding it over the stop sol then you wont have smart spider immobilisation.Your car has the later Bosch DDS immobilisation where the unit over the stop sol works in conjunction with the alarm ecu.The ecu you have in the footwell is probably the EGR control unit.
