Yeah, the alarm does go off, when the battery is going flat. If you havent done so allready, give it a little run on the motorway with everything switched off. If not, I think there is a guide to swapping a battery on the forum somewhere.

Not really separate, but if for instance you cut the battery leads the alarm should go off!

The same if you just disconnect the battery to change it for a new one.

The alarm senses the battery volttage and when it falls outside set limits the alarm goes off!

This can be a real pain if you have a flat battery and cant turn the alarm off. ( I had this happen a while back, the alarm was going off constantly as the car battery charged up, it was only when it had been charging for a good while that I could turn the alarm off, luckily the neighbours saw/heard the funny side ...)

failing alarm battery is not going to set the alarm off continuously... low main battery can tho.

If the alarm keeps going of then it thinks something is wrong... could be a dodgy door/bonnet/boot switch contact...

try turning off the interior sensor.. these have a habit of reporting intrusion faultily

You need someoen with VAGCOM to look at the alarm trigger info on the central locking controller - will tell you what set it off... until then the only answer is to unplug the alarm which you can do by reaching through the flap on the LH of the boot... although as suggested its tricky unless you have small hands...
