Throttle Valve Body 13541439580-06 408 238 425 005Z For BMW N20 4-Cylinder Turbocharged Engine

Throttle Valve Body 13541439580-06 408 238 425 005Z For BMW N20 4-Cylinder Turbocharged Engine

1. Vehicle Compatibility Table

This throttle valve body is compatible with a range of BMW models equipped with the N20 4-cylinder turbocharged engine.

Important Note: Final compatibility must be verified using your Vehicle Identification Number (VIN).

2. Product Introduction (Purpose)

    Serves as the engine's "intelligent throttle," precisely controlling the volume of air entering the engine's combustion chambers. This directly impacts power output, fuel economy, and emissions.

3. Features

• Electronically driven motor

• Dual integrated position sensors (redundant design)

• Precision gear transmission

• Aluminum alloy housing

4. Advantages

• Rapid Response: Offers faster throttle response and more immediate acceleration compared to mechanical systems.

• Fuel Efficiency: Works in synergy with the engine management system to maintain optimal air-fuel ratio, reducing fuel consumption.

• Smooth & Reliable Operation: Ensures stable idling and dependable performance.

5. Technical Principle

    The Engine Control Unit (DME) calculates the required throttle opening based on driver input and engine conditions. It sends a command to the throttle body's motor, which adjusts the throttle plate via gears. The dual sensors provide real-time feedback on the plate's position, creating a closed-loop system for precise control.

6. Service

    After replacing or cleaning this component, a "Throttle Adaptation/Alignment" procedure must be performed using a professional diagnostic scanner. This allows the ECU to relearn the throttle's limit positions; failure to do so may result in idle instability or other issues.
