How does the Audi A6's air suspension work?

I've been looking at purchasing an Audi A6 and I've noticed it has air suspension. Could you explain how it works and if it's worth the extra cost?

The air suspension in the Audi A6 utilizes air filled bags in place of traditional coil springs. This allows for a more comfortable and adaptive ride, as the air pressure can be adjusted to various road conditions and driving styles. In my personal experience, it's worth the extra cost for the added luxury and performance benefits.

The air suspension system in the Audi A6 uses sensors and electronic control to adjust the height and firmness of the suspension, providing a smoother and more stable ride. However, it is also more prone to maintenance and repairs compared to traditional suspension systems.
