Peugeot 306 indicators stay on all time, please help!!

Alarm ECU has a sticking relay in it. Common fault. Search Google groups and you will find may posts regarding this.

I did one of these last week with the same fault,, turned out to be the "indicator / light switch" that was at fault fitted a new one,,,, problem solved Fitzy

Indeed this is another possibility but my money is on the alarm ECU.

That is your alarm going off. You should be hearing a loud siren too, unless you've disabled it !

Er, you stop the alarm by pressing the button on your keyfob ! The steering column button simply disables the interior sensors.

I think you need to read your owners manual, to understand the alarm system !

Alarm controller often starts to stick, leaving one or more indicators switched on. But as the indicators flash whenever you lock/unlock the car with your keyfob, you'd surely have noticed the problem before now ???

It has two uses depending on when it is pressed.

It can be used to turn the alarm off. Open the door and the alarm will go off but get the key in the ignition and turn it on and press the button before 10 seconds and it will turn the alarm off. At least it does on my N reg 306.

Interesting ! Is that functionality mentioned in the manual ? I'm pretty sure it wasn't in the handbook for my 405.

Yes.
