My Xantia HDi broke down last week on the motorway. The car just came to a stop. After I has tha AA tow it back home, I have charged the battery, tried ti start it. It turns over but won't fire up. I have spoken to a bloke who said it may be the immobiliser that has kicked in. Any ideas how to reset/disable it. Oh, by the way, it is a 2001 HDi without the keypad immobiliser.
Thanks in advance
