Electronic Throttle Body for Vauxhall Antara & Chevrolet Captiva 2.0 D | OEM 4816305

The Throttle Body – Vauxhall/Opel Antara & Chevrolet Captiva (OEM 4816305) is a direct-fit electronic throttle valve assembly engineered for turbo-diesel engines such as the 2.0 D / 2.0 CDTi variants used in Vauxhall/Opel Antara A and Chevrolet Captiva SUVs. This component is a key part of your vehicle’s air intake system — it regulates the amount of air entering the engine based on input from the accelerator pedal and the engine control unit (ECU). A functioning throttle body ensures accurate airflow control, stable idle speed, smooth throttle response and efficient combustion. Over time, deposits, wear or electrical faults can cause poor throttle response, stalling or check-engine warnings, so replacing a faulty throttle body with a quality unit restores performance and drivability.

Frequently Asked Questions (FAQs)

Q1: What does the throttle body do?
A: It is an electronically controlled valve in your engine’s air intake path that regulates the amount of air entering the engine based on throttle (accelerator pedal) input — crucial for proper air-fuel mixing and engine control.

Q2: Which vehicles is this part compatible with?
A: This throttle body fits Vauxhall/Opel Antara A (L07) and Chevrolet Captiva (C100/C140) models equipped with the 2.0 D / 2.0 CDTi diesel engines — make sure to check your existing part number before ordering.

Q3: What are symptoms of a failing throttle body?
A: Signs include rough idle, hesitation on acceleration, stalling, erratic throttle response, loss of power or a check-engine light — often indicating carbon buildup or electronic/actuator issues.

Q4: How is it different from cleaning the throttle?
A: Cleaning can help remove carbon and restore some performance, but if the throttle body is electrically faulty or mechanically worn, a new replacement unit is typically required for reliable operation.

Q5: Is installation difficult?
A: Replacing a throttle body typically involves removing intake hoses, unplugging electrical connections and securing the new unit with proper torque and gasket sealing — a moderate-difficulty job best done with the correct tools or by a qualified technician.
