Purpose and function in the 1.4 TSI engine

The described throttle body operates in the petrol engine's intake system, controlling the amount of air drawn into the intake manifold. In 1.4 TSI units, it is crucial for:

• stable idle speed,
• smooth throttle response,
• maintaining the correct air-fuel mixture ratio,
• cooperation with exhaust emission control systems.

Thanks to its factory design, the component maintains full compatibility with the electronics of VW Polo 6R, Audi A1 8X, and Seat Ibiza 5 vehicles with the 1.4 TSI engine, which facilitates diagnostics and adaptation after installation.

Benefits of using an original throttle body

Choosing an original VAG group throttle body reduces the risk of problems typical of low-quality aftermarket replacements. The most important advantages include:

• factory fitment to the intake manifold and electrical harness,
• proper cooperation with the engine control unit software,
• stable operating parameters across the full load range,
• lower risk of ECU errors and limp mode.

A used OEM component is a reasonable compromise between cost and durability, especially for maintenance repairs in older vehicles.

Technical characteristics and compatibility

The throttle body belongs to the Throttle Bodies category and is intended for petrol-powered engines. Its electronic design (controlled by an ECU signal) allows for precise control of the throttle plate angle, which is important for driving dynamics and fuel consumption. The component is factory-integrated with a stepper motor/electric actuator and a position sensor, so installation is limited to:

• mechanical bolting to the intake manifold,
• connecting the electrical plug,
• performing throttle adaptation using an appropriate diagnostic tester.

This solution shortens service time and makes it easier to restore the correct operating parameters of the engine after replacement.

Condition, origin, and practical application

The offered throttle body is a used component, sourced from the dismantling of a VAG group Audi vehicle. Such components are frequently chosen by workshops and individual users for maintenance repairs when they want to maintain original quality at a lower cost than in an authorized network. In many cases, installing a functional throttle body from dismantling effectively solves problems with fluctuating idle, jerking during acceleration, or the check engine light.

Support with selection and additional information

Before purchasing, it is worth verifying the part's compatibility with the specific engine version and vehicle model year using the OEM number or interchangeable numbers visible in the technical specification. In case of doubt, a good solution is to compare the shape of the body, the type of connector, and the mounting method with the element currently installed in the car.

If you are planning a comprehensive repair or upgrade of the engine area in your Audi and need other elements from the same group, such as throttle bodies, control elements, or intake components, check the available parts in the Audi Throttle Bodies category.
