Annoying Rattle

[rushy45]

I have a 2009 Auris 1.33, Had it a year and still unable to locate this rattle, sat in drivers seat it comes from door area on right, sounds close to my ear, thought at first it was the seatbelt tensioner but have held that and it still does it, tapped around rear door, it must be somewhere like inside door where I cant see, any ideas ?, Thanks...
