||
This is an Electronic Throttle Body (ETB) designed for various BMW gasoline engine models. It replaces traditional cable throttles and is directly controlled by the engine computer (DME). As a core component of the engine's air intake system, it precisely regulates the volume of air entering the engine, directly impacting power output, fuel economy, and emissions.
This part is compatible with numerous BMW models, including but not limited to:
| Model Series | Example Models (Partial List) |
|---|---|
| 1 Series | E81, E82, E87, E88 |
| 3 Series | E90, E91, E92, E93 |
| 5 Series | E60, E61 |
| X Series | E83 (X3), E70 (X5) |
| Z Series | E85 (Z4), E86 (Z4 M) |
Important: Always verify compatibility specifically for your vehicle using your VIN (Vehicle Identification Number) before purchase, as differences exist between model years and engine types.
Command Reception: The driver presses the accelerator pedal, sending a signal to the DME.
Integrated Calculation: The DME calculates the optimal throttle opening based on pedal position, engine load, speed, and other factors.
Motor Activation: The DME sends a command to the throttle body's electric motor, which drives a gear mechanism.
Valve Adjustment: The motor rotates the throttle plate, opening or closing the intake passage to control air intake precisely.
Feedback Loop: Integrated sensors continuously report the throttle plate's actual position back to the DME, creating a closed-loop system for accuracy.
Precise Control: Electronic operation allows for faster and more accurate air regulation than a mechanical cable, improving engine response and efficiency.
Integrated Design: Combines the motor, sensors, and electronics into a single, compact unit.
High-Quality Construction: Manufactured to OEM standards, typically using high-grade aluminum, ensuring durability and reliability.
Performance Restoration: Replaces a faulty unit to restore engine power, smooth operation, and fuel economy.
Emission Control: Helps maintain low emission levels by ensuring an optimal air-fuel ratio.
After installation, a "throttle adaptation" or "relearning" procedure is typically required using a professional diagnostic tool (e.g., ISTA/D) to allow the DME to learn the new throttle's parameters. Failure to do this may cause irregular idle or warning lights.
Replacement and calibration are recommended to be performed by a professional technician.
