Factory Direct Throttle Valve Body 280750151 For Benz M274 M270 Engines
1. Product Attribute Introduction
This is an Electronic Throttle Body (ETB) designed for Mercedes-Benz vehicles. It is a mechatronic component precisely controlled by the Engine Control Unit (ECU), acting as a key actuator for managing the engine's air intake.
Product Type: Electronic Throttle Body (ETB)
Core Function: Regulates engine air intake volume
Control Method: Electronically controlled by the Engine ECU via electric signals driving a motor (not mechanical cable).
2. Vehicle Compatibility (Examples)
This part is primarily compatible with Mercedes-Benz gasoline engines like the M274 4-cylinder, commonly found in:
| Model Series | Chassis Code | Example Engine Model / Notes |
|---|---|---|
| C-Class | W205 | M274 engine (e.g., C200, C250, C300) |
| E-Class | W212 (Facelift) | M274 engine (e.g., E200, E250, E300) |
| W213 | M274 engine (e.g., E200, E300) | |
| GLC-Class | X253 | M274 engine (e.g., GLC200, GLC250, GLC300) |
| GLA-Class | X156 | M270 / M274 engine (VIN verification required) |
| CLA-Class | C117 | M270 / M274 engine (VIN verification required) |
| A-Class | W176 | M270 / M274 engine (VIN verification required) |
| B-Class | W246 | M270 / M274 engine (VIN verification required) |
Important Note: Compatibility depends on the model year and engine calibration. The most reliable method is to verify compatibility using your vehicle's VIN (Vehicle Identification Number) to avoid incorrect purchase.
3. Primary Purpose
Core Function: Precisely regulate engine air intake to control the air-fuel ratio, thereby managing engine power output.
Fault Replacement: Used to resolve issues caused by a faulty throttle body, such as check engine light (e.g., codes P0121, P0221), unstable idle, sluggish acceleration, starting difficulties, and increased fuel consumption.
4. Production Process (Brief)
Involves precision manufacturing:
Casting/Machining: Aluminum housing is high-pressure die-cast and CNC machined for precise dimensions and smooth airflow.
Motor & Gear Assembly: High-precision micro DC motor and nylon/metal gears assembled in a clean environment for low noise and long life.
Sensor Integration: Non-contact Hall sensors or precision potentiometers are integrated into the assembly.
Sealing & Testing: High-temperature resistant seals are used. The complete assembly undergoes rigorous electrical performance testing, leak testing, and opening calibration.
5. Operation & Installation Method (Overview)
- Disconnect Power: Disconnect the negative battery terminal before starting for safety.
- Removal: Remove the intake hose, disconnect the electrical connector, remove mounting bolts, and remove the old throttle body.
- Cleaning: Clean the carbon deposits and sealing surface on the intake manifold flange.
- Installation: Install a new gasket, mount the new throttle body, torque bolts to specification, reconnect the electrical connector and intake hose.
- Adaptation/Calibration: This is a crucial step. Connect a professional diagnostic tool (e.g., Mercedes STAR Diagnosis/XENTRY), access the relevant control unit, and perform the "Throttle Adaptation" procedure. This allows the ECU to learn the new throttle's open and closed positions.
- Test Drive: Start the engine after adaptation, check for stable idle, and perform a road test.
