What is the function of the Audi A1's extended electronic differential lock?

I've heard that the Audi A1 is equipped with an extended electronic differential lock, but what exactly does this feature do and how does it benefit driving performance?

The extended electronic differential lock in the Audi A1 helps to improve cornering stability and traction control by monitoring and distributing power to individual wheels. My advice is to experiment with it on different road surfaces to fully understand its capabilities.
