182 Cup Standard Alarm - sometimes it beeps, sometimes it doesn't!

[Steve vRS]

Most of the time when I arm the standard alarm, the car just flashes it's indicators at me and that's it.

However, sometimes when I lock it, it beeps at me. All the doors and windows are properly closed.

Why does it do this?

Thanks

Steve

The beeping is actually the alarm playing up, do a quick search about it it, fairly common.

There is a technical note from Cobra telling the dealer how to fix it.

RS+15 is the fault code.
Your dealer should be able to fix this. Common fault.
