If the engine management light is on.one trick which worked a couple of times is to
disconnect one lead from the positive ( do not know if it makes any difference
between positive or negative). The alarm immeadiately went off and stopped as
soon as the cable was reconnected. The car started after that. Then the next day
same issue but when disconnecting the lead the alarm did not go off. May be
worth a try to get you to a garage. Another fault, which we corrected last week,
was the ignition actuator in the cylinder barrel. If you have no resistance from the
ignition barrel when turning the key this could be the fault.
