Brand new here

Girlfriend has a 2012 Fabia VRS DSG. The alarm will randomly go off when parked up for what seems no reason. Alarm can be stopped, then a few minutes later will go off again. Any ideas?

Welcome.

Bonnet catch maybe. Not allowing proper closure.

Car battery charge, the siren is supposed to be changed at 5 years according to the Servicing Schedule but few have had that done.

 

Mouse in the car or big spider, do not tell her that.

 

Someone that has experienced the same will be along, there are others had the same issue. There are other threads here with their experiences.

Can you make any difference to the alarm from going off by pushing the button on the drivers door inside.

 

EDIT.  Here is one.

More threads if you do a google or search.

Thanks man! I definitely won’t mention the mouse/spider thing, she’ll never drive again!

 

she has warranty so I’m going to ring about it in the morning.

for now I have removed the fuse 

Windows and/or sunroof slightly open, weak battery, unclosed door/boot/bonnet or dodgy sensors. Parked in windy condition or where temperature fluctuates a lot?

Thanks for the reply! I’ve checked the windows, doors, boot and bonnet and seems fine. I’m sure it’s the battery, it’s being looked at on Saturday so hopefully the root cause will be found!

I might be wrong or it might be a mk1 thing but somewhere I remember reading that on the vrs, the alarm has its own additional battery so the alarm is active even if a toe rag disconnects the main battery. Symptoms of that failing are alarm going off randomly.

 

Try a search for alarm battery.

Local owner contacted me with the exact same fault. I have VCDS and diagnosed it as a flat battery in the siren. He changed it and the fault went.
