Ok Marnie - I have essentially the same as you except mine isn't dsg. The fact that your wheel says 'S Line' is irrelevant to the question.
If you want a FBMFSW with DSG paddles you need :-
The wheel including suitable airbag. Yours will NOT fit fbmfsw.
Steering control module as listed on here as 1K0Steering Wheel Control Module Versions - Ross-Tech Wiki which is 'Type 2' 'Highline' 'Yes'. SW version not critical afaik.
The alternative steering control module is 8P0 953 549 F which is compatible for both mfsw, fbmfsw and CC.
CC can be fitted separately should you so wish by the addition of the new stalk and lower cowl.
All this will have to be coded using VCDS.
Come back with a supplementary question if this is not clear.
