The ESP button is responsible for controlling the electronic stability control system, working in conjunction with the ABS system, acceleration sensors, and the brake controller.

• factory fit to the center console and wiring harness,
• correct operation with the onboard electronics,
• clear, intuitive control of the ESP function.

The button's construction is integrated with the factory connector, which facilitates installation and minimizes the risk of installation errors.

In practice, this translates to:

• stable electrical contact during repeated use,
• consistent operation with other center console buttons,
• preservation of the original operating logic of the Audi ESP system.
