Alarm beeping 4 times

[R11ysf]

My alarm would very occasionally beep 4 times a bout a minute after I locked it. It now does it every time I lock it and every time I unlock it.

I've googled and it says open door or boot but it definitely isn't. My car is a 2006 Mk3. Any suggestions please?

Bonnet switch ?

or

Is interior light extinguishing ? Interior light delay unit playing up keeping light on and at the same time switching a negative to the alarm in the same way as the door switches do

I keep the interior light off at all times so could the switch still affect it if the light is off?

Whereabouts is the bonnet switch please? I did take the bonnet off a few weeks back to try and find the horn so that sounds most likely!

Your door/boot/bonnet is/was open.

Yes, with the light off a switch fault will give the bleep of death

It is very often the bonnet switch

It is easily adjusted and is by the main bonnet catch.

I've spoken to Dave Fairclough (HF Solutions) regarding this subject whilst having some alarm/immobiliser issues. (These later turned out to be ignition switch related....bad contact or wiring to white/red tracer wire connected to switch).

His comments regarding beeps were along the lines of - "Ah, OK, that's usually caused by the courtesy light delay relay 'hanging' thereby causing the Meta to think a door is open....the delay relay can be random in it's timing to switch 'OFF'.
Nothing to worry about.
