*** UPDATE 22/10/16 ***
For anyone interested in this retrofit, I've finally got round to successfully completing the job. It is possible to fit an Octavia III-paddle shift MFSW (for those fancying the nice perforated leather/flat bottom type wheel), I believe several members have made this swap, but you will need to fit the Superb III buttons (part no. 3V0 919 719B) as the Octavia III buttons are not compatible on the Superb.
It may (though don't quote me), also be possible to buy the paddles (part no. 3V0 951 523?) and buttons from Skoda and fit them to a standard wheel as the boss looks like it is standard, though I'm not sure the paddles will come with the figment screws (N 909 680 02) (your local Skoda parts department should be able to help with this). You will require the 3V0 919 719B buttons as the standard, non paddle shift equipped wheel buttons, part no. 3V0 919 719A do not have the connectors fitted to take the paddle ribbon cables. No coding should be necessary.
Obviously now the Sportline has the very nice flat bottom paddle shift wheel fitted as standard to the DSG equipped car, this would be the easiest swap but probably the most expensive.
My advice would be to spec it on a new build if buying new but for those of us who fancy paddle shift as a retrofit, it is possible, but at quite a bit of expense. The buttons set me back £216. Wheels are quite often available on Flea Bay.
I just hope that after all the effort and expense, it was worth it.
