Facelift and steering wheel with 4 operating satellites ?!

Hello, I noticed in the configurator that you can also order the steering wheel with the button for the switchable exhaust at the Facelift. The sports exhaust system is no longer available. I have now bought a used V10 Performance Spyder (shown as soon as I have picked it up) and ask myself the question, if you can not retrofit the fourth satellite?! Technically, if the exhaust flap still available at the Facelift should not be an insoluble Prob lem be ?! Or is it just a mistake in the configurator ? Sincerely Norri
