How does the electronic power steering system work in an Audi A2?

I am interested in understanding how the EPS system operates in my Audi A2. What components are involved and what is the overall functionality of the system?

The EPS system in Audi A2 uses an electric motor to assist with steering, reducing the effort required from the driver. It works by measuring the torque applied to the steering wheel and providing the necessary assistance to turn the wheels.

The EPS system also includes sensors that detect the speed of the vehicle, allowing for different levels of assistance depending on driving conditions. For example, at higher speeds, less assistance is needed as the car is already more stable.
