My car is a 2000MY V70 2.5D - UK spec. (old shape).
For the past couple of days the alarm status indicator (just behind the bottom centre of the windscreen) flashes furiously for a few seconds every time the ignition is turned on - and then settles down ok.
The driver's handbook suggests that this may indicate a fault in the alarm or immobiliser system. However, the car locks and drives perfectly normally - and the status indicator flashes once per second, as normal, when the car is parked and locked.
Can anyone throw any light on what the fault might be, what its likely consequences are, and how to fix it?
TIA.
