Zestek Racing SCX Pro OEM Steering Wheel Control Panel - Audi S4 | RS4 B9

The Zestek Racing SCX Pro OEM uses a vehicle-specific PCB and harness to connect to the Audi S4 and RS4 (B9)'s original steering wheel circuit through the factory clock spring, so the supported factory buttons keep working once a compatible aftermarket wheel is fitted. Choose the Factory Functions + Standalone ECU configuration and the SCX Pro adds a second signal path to a standalone ECU, display or CAN network alongside the factory controls. Buttons, rotaries, RGB colours and RPM shift lights are all set up in Zestek Workstation over USB-C.

Please note: The images show the optional Zestek Racing SCX Pro Motorsport Curly Cord, which is sold separately and is required for the standalone ECU connection. The Zestek Racing Boss Kit for Audi, Porsche and Volkswagen and an aftermarket steering wheel are also required and are sold separately. This version is for cars still running their OEM ECU – dedicated race cars with no factory functions to keep should choose the Zestek Racing SCX Pro Steering Wheel Control Panel (Standalone ECU Only). Please let us know when ordering whether you need the factory functions only or the Factory Functions + Standalone ECU configuration, together with details of your standalone ECU, display and CAN setup. CAN stream configuration, Haltech keypad emulation, Custom Open CAN and the built-in CAN analyser all require the separate motorsport connection. Supported factory functions vary by vehicle, so please let us know which original controls you need to keep before ordering. Zestek states that its products are intended for off-road and motorsport use only; regulations differ between countries, so please check with your local authority.

Fitment

• Audi S4 (B9)
• Audi RS4 (B9)
• Not suitable for: Audi S4 and RS4 (B8) – see the Zestek Racing SCX Pro OEM Steering Wheel Control Panel for the B8
• Not suitable for: race cars with no factory steering wheel functions to keep – see the Zestek Racing SCX Pro Steering Wheel Control Panel (Standalone ECU Only)

The SCX Pro replaces the factory steering wheel and connects to the original clock spring via the vehicle-specific harness. We strongly recommend professional fitting, particularly for the Factory Functions + Standalone ECU configuration where both the factory harness and motorsport connection must be terminated correctly; incorrect installation may void the warranty. Select the correct adapter for your car in Zestek Workstation and run the function test before driving. Pair it with the Zestek Racing Carbon Fibre 330mm Steering Wheel and the Zestek VeloSwitch, which adds eight wireless relay channels.
