Purpose and configuration of the set

The presented electronic set is dedicated to Mini One R55 and R56 generation models equipped with the N12 1.4 N12B14A 95HP petrol engine. The set includes the DME (ECU) engine controller, the CAS3 module responsible for ignition authorization, and two keys compatible with this system. This configuration allows for the consistent transfer of the entire control and security system from one vehicle to another.

Benefits of using the complete ECU + CAS3 + keys set

Using a complete control set in a petrol-powered Mini offers a number of practical advantages:

• maintained compatibility between the engine controller and the CAS3 module,
• two keys matched to the set,
• simplified vehicle startup procedure after installation,
• reduced need for advanced programming from scratch.

For workshops specializing in the Mini brand, such a set is a convenient solution when replacing a damaged controller or performing repairs related to the immobilizer and starting system. Consistency of powertrain electronics helps reduce diagnostic and installation time.

Application in the petrol engine control system

The electronic control module from this set operates in a system with a petrol-powered engine, which is important when selecting the appropriate ECU for a specific powertrain. Proper matching of the controller to the fuel type is crucial for correct mixture dosing, ignition control, and cooperation with other sensors and actuators in the engine bay.

In practice, this means that the set is intended for Mini One vehicles that were factory-equipped with the N12 1.4 N12B14A 95HP petrol engine, and its installation should be carried out by a service center with experience in this brand's electronics.

Product characteristics and condition

The set belongs to the Electronic control modules and controllers group, which means it is responsible for key functions related to powertrain operation and ignition authorization. The product is used, making it an economical alternative to new components while maintaining the manufacturer's original specifications. For many Mini users, this is a reasonable way to restore vehicle performance at controlled repair costs.

Selection and additional technical information

Before purchasing, it is worth verifying the compatibility of the set with the specific equipment version and model year of the Mini One R55/R56. Available OEM part numbers and interchangeable numbers can be helpful, allowing for precise matching of the module to the existing installation. In case of doubt, it is recommended to consult an automotive electrician or a service center specializing in the Mini brand.
