    With the proper scanner(i.e. hawkeye) u can choose some immobiliser settings which will make your life easyer or even disarm it for good.

    not yet but ive been told the ones with them are from chassis number T onwards, mines an S. Ive also been told that the spider was introduced in 1996 and its the trickiest year to rectify.

    Just thought id prepare myself for the worst (and a plan b)

    so incidentally what if i havent got one? new immobiliser? fob and ecu etc?

    I'm not an auto electrician, but if I ever get to spider problems and can't do 'the usual' fixes like re-soldering bad joints etc, I'd be inclined to look at going back to first principles and somehow run a different fuel solenoid via the ignition switch and do without the alarm at all. Not bypass it, just remove the thing completely!

    I have no clue about the details but I guess it can't be too hard, all the solenoid needs is a feed when you want it to run and no feed when you don't .. ;)

    Why would yu want to add more complication? It seems like you are trying to fix the symptoms, not the cause of any problem. What exactly is the problem?
    How do yu know your imobiliser is sticking on? What makes you think its an imobiliser problem?

    Hi my problem is the immobiliser came on yesterday for no reason, and 4 hours later inexplicably sorted itself out. (see this http://www.landyzone.co.uk/lz/f8/disco1-v8-immobilisor-problem-111605.html )

    it may never happen again, or could happen at any moment when the mrs and kids are in the middle of knowhere with no phone signal.

    I would just like to basically see what my options are from fixing to removing and go for the option that best suits me (and my pocket).

    Ive spoken to a guy on ebay who sells spider bypass units and explained my problem and he sais it sounds like the spider unit being faulty (comes on for no reason and then for no reason it goes off some time later.

    I know very little about the possible causes and fixes related to this problem and would like to gleam as much info as poss for my own peace of mind (ooooooh, i may not have a spider unit, if not what next type of attitude) I just like to know that things can be sorted one way or another and i dont stress as much then.:)

    mrnice, If you have uk spec disco with a two button fob system you will have as standard 'passive immobilisation' and therefore the reason is, the engine is immobilised automatically. More info can be found in your owners handbook

    cheers buddy your a star. I do have the UK spec disco with the 2 button fob so i will have a look into "passive immobilisation" but we leave the key in it all the time and did nothing out of the ordinary yesterday.

    Ive just pulled the radio out aswell and i think ive found the spider! is it a black box about 3"square situated under a metal bracket slightly to the N/S, it felt like it had a connection going into it on the O/S.

    That link is the best one I've seen yet about this subject.

    Paul D, when / if you need yours doing, the hardest part is faffying around dissassembling the bloody dash. Job should be done and dusted in 2-3 hours easy.

    I have just replaced my radio and I had a look-see with a mirror on a stick thingy but didn't see anything so I stuffed a load of wires down there. The metal surport bracket will have to be cut out to get below it but that may be a better way of accessing the spider "if" the bracket could be removed, there's not much room to do that, but maybe better than taking the front of the dash apart :)

    Funnily enough .. been out to have a look while there's still no seats in so access isn't an issue .. easy peasy, right behind the radio no sweat.

    ;)

    I've no worries about soldering either, done our lasses Micra throttle body and used to race electric model cars that needed soldering every time we changed motors .. and batteries and radios etc etc ... ;)
