Throttle Body 04C133062C Reference Compatibility Table

Key Features

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.
