VW Skoda Audi Electronic Throttle Body 038128063M for EA888 1.8T 2.0T Engines 2011-2018 Models

Primarily used in Volkswagen Group vehicles equipped with EA888 series engines such as 1.8T and 2.0T.

This Electronic Throttle Body (ETB) serves as the core actuator for the engine's "Drive-by-Wire" technology.

1. Command Reception: The ECU calculates the optimal throttle opening based on the accelerator pedal signal and vehicle status.
2. Motor Drive: The ECU sends commands to drive the miniature motor inside the throttle body.
3. Gear Control: The motor controls the valve plate's rotation angle through precision gears, accurately regulating airflow.
4. Feedback Adjustment: Dual sensors on the valve shaft provide real-time position feedback to the ECU, forming a closed-loop control to ensure precise opening.

• Core Function: Precisely controls engine airflow, determining power output.
• Idle Speed Control: Maintains stable engine idle.
• Feature Support: Key actuator for functions like cruise control and traction control (ASR/ESP).

Utilizes precision manufacturing processes:

1. Aluminum alloy die-cast housing
2. CNC high-precision machining of critical parts
3. Motor and sensor assembly in a cleanroom environment
4. Application of specialized long-life grease to the gear set
5. Each unit undergoes rigorous testing and calibration before leaving the factory

1. Disconnect power
2. Remove intake hose
3. Unplug connector
4. Remove bolts
5. Remove old unit

1. Clean mating surface
2. Install new unit (replace seal)
3. Tighten bolts to specified torque
4. Reconnect connector and hose
5. Restore power

After installation, must perform "Throttle Body Basic Settings" using a professional diagnostic tool to allow the ECU to learn the new throttle's parameters. Failure to do so may cause irregular idle, poor acceleration, etc.
