Just to confirm chaps my 2012 4/4 Sport had a Sigma engine, was fly by wire and had an Organ Pedal.
The pedal was the normal roller end under (and inside the long slider hole) on the Organ pedal. Looked identical to other cars I have had. As I say no idea if someone modified anything as I asked AWSC to remove it before Shaun made me a full carpet set for the front as I preferred that to the rubber mats.
Hope that helps
