Ignition problem, immobiliser
I have an over-zealous immobiliser on my 156 - it's so vigilant that it sometimes won't allow the actual key to start the car.
The problem is intermitent and not always when I first start it in the morning: I turn the key, all the lights come and go apart from the 'code' one which stays on leaving me stranded. It usually heals itself after I repeat the starting procedure or get out, lock and unlock the car and try again (my spare key doesn't seem to help). I don't think its the battery in the key fob as the remote alarm works at about 150 yards!!!
Any advice gratefully received. Cheers
