Throttle Body 04C133062C Reference Compatibility Table

Key Features

• Genuine/OE Quality: The part number 04C133062C is an original equipment (OE) number for the Volkswagen Group. This means its specifications, materials, and performance are identical to the part installed on the vehicle at the factory, ensuring perfect compatibility and reliability.

• Integrated Sensors: It contains built-in position sensors that provide real-time feedback to the ECU on the valve's angle, enabling precise closed-loop control.

• Actuation: The plate is operated by a precise electric motor instead of a mechanical cable.

Common Symptoms of Failure

When this throttle body starts to fail, you may experience:

• Check Engine Light illumination.

• Irregular, rough idling, or stalling.

• Lack of power, sluggish acceleration.

• Abnormally high fuel consumption.

• Hard starting.

Maintenance Advice

• Over time, carbon and oil deposits can build up on the back of the throttle plate, causing it to stick or respond sluggishly. Regular cleaning (typically recommended every 25,000 - 40,000 miles / 40,000 - 60,000 km) can prevent many issues.

• If problems persist after cleaning, or if the motor or sensors are faulty, the entire unit must be replaced.

• After replacement or cleaning, a throttle adaptation (basic settings) procedure must be performed using a professional diagnostic scan tool. This allows the ECU to relearn the throttle plate's positions; otherwise, you may experience high idle speeds.
