When I locked and deadlocked my car today with the remote, I happened to check the flashing led on the hazard light switch, and noticed that rather than being lit for 10 seconds and then flashing occasionally, it flashed quickly for 10 seconds and then settled down, to occasional flashes. These flashes MAY have been more rapid than when the alarm was working properly, but I can't be sure. The main thing I noticed was the rapid flashing for the first 10 seconds or so.
I've opened and closed every door, the boot + the bonnet (bonnet switch looked a little worn but still seems to operate) and I did a paperclip test just incase, but theres no faults. The Astra handbook says a quick flashing of the lights indicates a system fault... is this something I need to get checked by Vauxhall?
Car is a 1999 Astra 5 door CDX, x18xe1
Thanks in advance
