Please help me unravell my latest Puma puzzle.

I am getting a single 'beep' from the area of the instrument cluster when I am slowing to a stop or when I have pulled up with the motor still running. It seems random but is increasing in frequency.

The pitch sounds a bit similar to that of the low fuel warning sound, but is only active for only a fraction of a second instead of the longer drawn out beep of the fuel warning. My tank was full today when it was happening.

Behind the dash the only non standard gear is a belkin car charger that services my VMS GPS which is mounted in the center of the dash, and a piezo buzzer that warns me when If I leave my headlights on, which doesnt sound as short or quiet as the mystery beep.

Has any one else experienced this? Any help is appreciated.
