As the title says,my indicators don't always flash when locking the car,they do flash once when unlocking,does that mean the alarm isn't set,all the doors lock as does the boot,the alarm went off yesterday I assumed it was something inside the car set it off it hasn't done it since,could it be related.

Im sure 1 flash is set, and 3 flashes means something is not correct, like a door switch is open or something?

3 flashes in locking indicates all ok. If no flash, there is something in the system which 'prevents' decent locking. Often this is door pin switch or boot switch. Door will lock but car thinks one is open. If the pin switch is at trigger range, wind or something may move the door and system believes someone is trying the door and alarm goes on. Are the inner light playing, not going off when shutting doors, coming on during the drive etc? Check also there is no vacuum leak in door lock, delayed locking may cause troubles too.

Thanks, I knew I got it the wrong way round :)
