I have a 1998 Citroen Xantia 1.9 Turbo and twice now have had the
immobiliser come on and render my car useless. The first time it happened
I was at Calais and had to be towed 100 miles home, however the next
morning the car started without a problem. The second time it happened
was at home approximately 9 months after the first time. Can anyone
explain why this is happening and how to stop it/manage it please.
