Technical characteristics of the Mini N14 throttle body

The presented throttle body belongs to the Throttle Bodies category and is factory-designed to work with N14 petrol engines. The body construction and bore diameter are adapted to the requirements of the power units used in Mini R55, R56, R57, R58, R59, and R60 models, ensuring proper airflow and compatibility with the stock intake system.

The component works with an electronic engine control system (drive-by-wire), allowing the ECU to precisely regulate the throttle opening angle based on load, engine speed, and accelerator pedal position. Appropriately selected operating parameters help maintain stable idle speed, proper acceleration dynamics, and correct exhaust emission values.

Compatibility and reference numbers

The throttle body has been developed as an OEM part for the Mini brand, meaning full compatibility with factory wiring harnesses, intake manifolds, and engine control unit software. The manufacturer has assigned it a dedicated OEM part number and a set of interchangeable numbers, which simplifies selecting the correct component for replacement in a specific N14 engine variant.

Thanks to the presence of reference numbers, it is possible to quickly verify compatibility with a specific equipment version and vehicle year. In practice, this means that when selecting a part, you only need to compare the markings with the removed throttle body or with the service documentation to be sure that the chosen component will work with the existing engine accessories.

Application in petrol engines

The throttle body is designed for units powered by petrol fuel, which is important both for air flow characteristics and engine control unit calibration. In N14 engines, a properly functioning throttle body affects:

• stable idle speed and reduced idle fluctuations,
• smooth response to accelerator pedal input,
• maintenance of the correct air-fuel mixture across the entire load range,
• proper interaction with exhaust emission control systems.

In cases of symptoms such as jerky acceleration, delayed throttle response, stalling at idle, or appearing ECU errors related to throttle position, replacing with a functional unit from this series is one of the basic diagnostic and repair steps.

Condition, selection, and benefits of using OEM parts

The offered throttle body is a used part from the aftermarket, which significantly reduces repair costs compared to a new part, while maintaining the original manufacturer's specifications. For the user, this means:

• maintaining the factory operating characteristics of the Mini engine with the N14 unit,
• no need for electrical or mechanical installation modifications,
• easier adaptation in the engine control unit compared to low-quality aftermarket alternatives.

Before installation, the standard procedure is recommended: check the condition of the electrical connector, the seal at the connection to the intake manifold, and perform throttle body adaptation using an appropriate diagnostic tester, according to the service procedure for N14 engines.
