    Hi,
    I am new to this forum so please be gentle
    I have a problem that started about 3 weeks ago that I cannot seem to get resolved and would like some help if possible.
    Begins like this, had car for 3 years no issues,came home, parked on drive.
    About 1 hour later went out to car and tried to start,wouldn't and seemingly, "No reason" phoned a friend he came but still no joy! abandoned car and got a lift.
    Next day I noticed the amber Key in Lock symbol was illuminated!(Immobiliser)
    Phoned Citroen, (Who said, could be key, could be ariel, or Ecu!)
    £50 to tow in, £100 for Key,£65 for responder ariel or Ecu= Megabucks....
    Had a word with another Mate who suggested "ECU-Doctor in Plympton" To get Ecu unlocked. Four days later Ecu back with report, already unlocked tested all OK.But still no starting.....
    Tried another set, (From another Saxo) ECU+Transponder Key+Responder + Immobiliser......Light still flashing, Car still not starting???
    Am I missing something simple? All Fuses intact,Fuel pump tested ok, (External power)
    Any advice gratefully received

    does it turn over?
    Does it splutter?

    Turns over as normal, doesn't splutter but can make it fire spraying "easystart" into airbox

    Central locking by key all work, have never had a Fob,(No apparent receiver,No alarm,No audible warnings)
    Is there any way to input code manually?No Key pad..(My Range Rover can be from Drivers Door!)
    Is there any way to bypass immobiliser?
    How does immobiliser work? (I believe it to be on fuel system) Fuel pump will run on external wiring, but no fuel pressure at manifold?

    The immobiliser is a transponder chip in the key, behind the casing around the ignition barrel is a ring that picks up the chip, I had one in a vtr that slipped and lost the signal so worth checking that. Only way to bypass the immobiliser is by having it started then while the engine is running unplug the receiver otherwise it will be an auto electrician that knows what they are doing at removing and re wiring the ignition area.

    Sorry,but I think you are confusing things.....
    The Immobiliser is a black box,situated near the fuse box that can be removed when car is running!
    The transponder chip, is just that. I have tried new Key and ring, immobiliser box and even ECU {All matched from another Saxo} - With No Change!
    What I am trying to ask, IS,
    Does flashing keylock,(Amber light) signify anything else? (Other than immobiliser)
    Also noticed that my OBD scanner that previously worked on car, now shows no connection with ECU, but does supply power?

    nope, orange light is immo and immo only.

    funnily enough, when i had an unlocked ecu for mine, i couldn't get my lexia to "talk" with the BSI, just said no dialog...might be related.

    the subject of the immo seems to be a bit of a dark corner.
