The F20 uses Variable Sport Steering, not the older but complex Active Steering. It reduces the number of steering wheel rotations required to make sharp turns. It is a much simpler mechanical system, steering ratios are adjusted using a variable steering rack.

So not influenced by 'interventions', it is simply a different ratio along the rack, but still a repeatable mechanical link.
