Sorry to hear of your situation - it must be terrible for you.
The immobiliser number IS REQUIRED as it is effectively a switch in the engine management
ECU that will allow the engine to run. Without it the car cannot start and run. Be careful not
to try any old number as it will lock you out for 10-30 minute period after 3 failed attempts.
The expensive guaranteed route is to find a replacement ECU with a known code either from a car
being broken or borrowed from another Xm but the ECU has to be off an identical engined Xm to
stand any chance of working properly although a manual/automatic gearbox difference may not
cause problems though I've heard it suggested they may be different too!
What specification/engine is the car?
The alternatives are what you have tried already checking through the documentation. Has a
garage/specialist carried out work regularly (even MOT centre) where they may have a record
of the 4 digit code in their paperwork?
Alternatively check where the number may be saved. I've seen them written on the back of the sun
visor, the same number as the replacement parts number on the bonnet release side front door
pillar.
Other options include 1111 which is on many cars as the original code has never been activated from
this 'garage setting' and a year or birth ie. 1939 etc. If you try this remember 3 strikes and you're
locked out - not 100% certain but switch off the ignition after 2 attempts and try again switching it
back on?
Hope you manage to get somewhere with this. What plans do you have for the car and where are
you located should anyone have a similar ECU to try?
