Rear Screen Heater Module Location

[Dakes55]

Does anyone know where the rear screen demister control module is located on a 2002 2.8 FL quattro, the manual states that its behind the right hand side panel in the boot, but on mine its not, I have taken off both side panel covers and plastic covers on both sides of the boot, and on the left side there is only the central locking pump and alarm module, on the right hand side there is nothing there, any ideas where else to look?
Thanks
