Zestek Racing SCX Pro OEM Steering Wheel Control Panel - Mercedes-AMG A45 | CLA45 (W176)

The Zestek Racing SCX Pro OEM Steering Wheel Control Panel lets you fit an aftermarket steering wheel to your Mercedes-AMG A45 and CLA45 (W176 platform) without losing the supported factory steering wheel buttons. A vehicle-specific PCB and harness connect the panel to the original steering wheel circuit through the factory clock spring, designed specifically for this car rather than adapted to suit it.

Choose the Factory Functions + Standalone ECU configuration and the SCX Pro adds a second signal path, allowing it to communicate with a standalone ECU, MoTeC display or CAN network alongside the factory functions. Buttons, rotaries, RGB colours and the RPM shift lights are all set up in Zestek Workstation over USB-C.

Specifications

• Factory functions: retained via a vehicle-specific PCB and harness through the original clock spring
• Construction: full dry-compressed carbon fibre faceplate with a metal rear housing
• Buttons: multi-stage tactile design with 2.25mm of travel and RGB lighting
• Quick release: pogo-pin type in 7075 forged aluminium, with integrated adaptor

Key Features

• Retains the supported factory steering wheel functions on the Mercedes-AMG A45 and CLA45 (W176 platform)
• Optional second signal path to a standalone ECU, MoTeC display or CAN network with the Factory Functions + Standalone ECU configuration
• Haltech CAN keypad emulation, or Custom Open CAN for Emtron, MoTeC, Link and FuelTech (standalone configuration)
• Programmable buttons, rotaries and RPM shift lights, with RGB brightness adjustable on the panel itself – no laptop needed
• Magnetic paddle shifters 2.0, offering a wider adjustment range and a more positive shift
• Function test in Workstation for every button, rotary and paddle before the car moves
• Configurations can be exported and imported, so a set-up can move to another car or be sent to your tuner
• Full dry-compressed carbon fibre and metal construction, an upgrade over the carbon composite used on the SCX and DRX

Please note: A boss kit (the Zestek Racing Boss Kit - Mercedes-Benz A45 | C63 | AMG GT) and an aftermarket steering wheel are required and are sold separately. The motorsport curly cord shown in the photos is optional and sold separately. It is required for the standalone ECU connection. This panel is for cars still running their OEM ECU. The SCX Pro is offered in a Factory Functions configuration or a Factory Functions + Standalone ECU configuration – please tell us which you require when ordering, along with your standalone ECU, display and CAN set-up if applicable. CAN stream configuration, Haltech keypad emulation, Custom Open CAN and the built-in CAN analyser all require the separate motorsport connection. Button assignments, RGB colours, shift lights and status lighting work the same on either configuration. Exactly which factory functions carry over depends on the vehicle and its remaining factory electronics – please let us know which controls matter to you when ordering. Most aftermarket steering wheels suit the SCX Pro. If you're unsure about yours, please ask us before ordering. Zestek states this product is for off-road and motorsport use only.

Fitment

• Mercedes-AMG A45 (W176)
• Mercedes-AMG CLA45 (W176 platform)
• Not suitable for: the later Mercedes-AMG A45 S and CLA45 S
• Not suitable for: dedicated race cars with no factory steering wheel functions to keep – these need the Zestek Racing SCX Pro Steering Wheel Control Panel (Standalone ECU Only)

Installation

The SCX Pro replaces the factory steering wheel and connects to the original clock spring via the vehicle-specific harness. Although designed for straightforward installation, professional fitting is recommended – particularly for the Factory Functions + Standalone ECU configuration, where both the factory harness and the motorsport connection must be terminated correctly. Incorrect installation may void the warranty, and Zestek is not liable for damage caused during installation. Once fitted, select the adaptor for your car in Workstation and run the function test before driving. Zestek also offers a remote Express set-up session.

Complete the set-up with Zestek's matching parts: mount the panel with the Zestek Racing Boss Kit - Mercedes-Benz A45 | C63 | AMG GT, pair it with the Zestek Racing Carbon Fibre 330mm Steering Wheel. The Zestek SCX Pro Motorsport Curly Cord adds the standalone ECU connection and the Zestek VeloSwitch adds eight wireless relay channels.
