   1998 Citroen Saxo 1.5 diesel immobilizer fault?
   
   Hi Friend does anyone have fix for this immobilizer fault
   When I insert the ignition key and switch on both the red and green light on the keypad come on together after a second or two I have tried punching in the correct code into the keypad but both the lights stay on and this prevents the car from starting ,,,, I found this fix on the internet which said turn the ignition on for half hour or so to see if this will clear the fault then switching off and removing the key and then reinserting the key and switching on I have tried this but it does not clear the fault so can anyone advise me what the problem is and a fix if one is available.I have not used the car for 8 weeks and prior to this I had no problems at all with starting the car
   
   many thanks and best regards to all readers ant(musicmutt)

   I`m not promising this will work but try disconnecting the battery for a while might clear the fault,other than that i`m stumped.

   Hi Steve many thanks for the reply unfortunately the suggestion of disconnecting the battery did not work I left it with both terminals off for almost 8 hrs
   
   Anyone else have any suggestions that may resolve the problem

   HI Mr Fox I did ring Citreons as you suggested and they could give me no straight answer just buy a new immobiliser and keypad and have the lot recalibrated or a large fee so no joy there ,,,,, many thanks for your interest best regards Tony

   Hi all I found the fault just by chance I decided to check all the connections to the ecu and immobiliser block and found a wire broken in the harness near to the imobilizer block so I joined it with an electrical connection block and re-taped it up with insulation tape and it now accepts the code and it starts ,,, so when I now switch on just the red light comes on and when the code is entered it goes off and the green light comes on and it starts first time as it always did so a big thank you to all who responded with suggestions job done best regards to all
