How to Turn on VW Fog Lights | Volkswagen Golf/Polo/Jetta/Passat/Tiguan/GTI/GLI 

Does your switch pull out at all even though you dont have fogs? If it does then i think you could use that switch but if not then youd probably have to look at getting a euro switch which has all the settings like parking lights and both front and rear fogs. Thats how mine is at least. Id have to get a euro switch to get rear fog functionality. Then if there aren’t any kits out there for the mk7 Rs you could look at getting mk7 gti fog harnesses to use with that switch and then lights that fit your bumper.
