I have read through many of these forums but unable to find a solution to my problem, a 1997 Scenic 1.6 petrol.
This does not work with key or manual switch on dashboard. I have checked all fuses and even removed the fuseboard/immobiliser unit to see if there was a loose connector etc. When I operate the key or manual button you can hear a relay operate on the fuse board but thats it.
The immobiliser light flashes. When you operate the central locking the immobiliser light goes out (remember above, c/l does not work properly) but when I insert key in ignition, turn on the immobiliser light stays off, cannot start car.
I have tried the emergency code and re-sync of keys but cannot do any of these because the immobiliser light does not respond to any of my inputs.
This problem has been around for a long time, intermittantly. Normally after a short rest the car will start but now she is completely dead. I suspect a new Fuse box/
Can anyone shed light on my problem before I tow car to a Renault dealer.
