It would seem after some more investigation and 'playing' that this is standard on FR but only an option on SE etc.
I believe with time I should be able to 'Long code' via Vag-com to allow it to work on all models fitted with electric mirrors.
I may well have in the next few weeks an engineer from a well know vehicle electrics/equipment manufacturer coming to look at my car as it would seem that they have never had one and as such none of their equipment or manuals are set up for the new Leon.
They believe that they could get 'ahead of the game' by examining it now, as other areas of the VAG could/will go this way.
We'll see...
