Wholesale Price Throttle Body Assembly 047133062D For VW Skoda Audi SEAT CAVC 1.4L TSI Twincharger Engines

Product Overview

The 047133062D is an electronic throttle body (ETC - Electronic Throttle Control) . It replaces older cable-operated throttles and is precisely controlled by the Engine Control Unit (ECU). It is a critical actuator within the engine management system.

Core Functions

1. Regulates Air Intake: Based on the driver's accelerator pedal position (signal sent from pedal sensors to the ECU), the ECU calculates the optimal opening command. An internal motor then rotates the flap to precisely control the amount of air entering the engine.

2. Idle Speed Control: At idle, the ECU finely adjusts the throttle opening to maintain a stable target idle speed, compensating for loads like AC compressor engagement or power steering operation.

3. Traction & Stability Control Integration: When systems like ESP/ASR intervene, the ECU can override the accelerator pedal signal and directly reduce the throttle opening to decrease engine torque and help restore vehicle stability.

4. Adaptation/Cleaning Mode: Under specific conditions (e.g., ignition on but engine not running), the ECU of some models may run a throttle adaptation or cleaning procedure, cycling the flap through its full range of motion.

Failure Symptoms

If this throttle body assembly fails or becomes excessively dirty, one or more of the following symptoms may occur:

• Check Engine Light Illuminated: The ECU detects a discrepancy between the actual and target throttle valve positions.

• Unstable, Rough Idling, or Stalling: Especially noticeable during cold starts.

• Lack of Power, Sluggish Acceleration: The throttle feels unresponsive, and power delivery is not linear.

• Increased Fuel Consumption: Incorrect air mass calculation leads to an improper air-fuel ratio.

• Abnormally High or Fluctuating Idle Speed.

Installation & Maintenance Notes

1. Adaptation/Programming: After installing a new electronic throttle body, a "throttle adaptation" or "basic setting" procedure is typically REQUIRED. This is performed using a diagnostic scan tool (e.g., VCDS, ODIS) to allow the ECU to learn the new throttle's limit positions (min and max opening). Skipping this step will likely cause idle problems.

2. Cleaning: If the issue is just sticking due to carbon buildup, professional cleaning can be attempted. NEVER manually force the electronic throttle flap open or closed, as this can severely damage internal gears. A basic setting is also required after cleaning.

3. Quality Selection: It is highly recommended to choose Genuine (OE), OEM (like Bosch, Continental), or high-quality branded replacement parts. Aftermarket parts vary greatly in quality; their precision and durability may not be guaranteed, potentially leading to recurring issues.

Purchasing Advice

• Confirm Need: First, read fault codes with a diagnostic tool to confirm if the throttle body itself is faulty or if it just needs cleaning.

• Verify Compatibility: Provide the accurate vehicle VIN to the supplier to ensure part compatibility.

• Choose Source: Purchase from reputable automotive parts suppliers, dealerships (4S), or authorized online platforms to ensure product quality and after-sales support.
