• precise response to steering inputs at higher speeds,
• proper integration with safety systems, such as lane assist or steering correction during braking.

Thanks to its design tailored to the Audi A6 C7 platform, this component works with the vehicle's factory electronics, maintaining the correct operating parameters of the steering system.

• factory mounting points for the steering rack housing,
• electrical connectors prepared for integration with the vehicle's wiring,
• compatibility with the vehicle's original control systems and software.

Such fitment translates into easier installation and reduces the risk of communication issues within the vehicle's network after replacing the component.
