Right just got all the boot trim off to tackle this ***** and I'm now after some guidance!
Can anyone confirm that the alarm and the batteries are actually part of the central locking pump???
I've plugged in the laptop and triggered the alarm and it seems to be sounding from the central locking pump. This is slightly different to the TT, as seen in this guide:
