VW Throttle Body - Genuine VW 03G128063Q

Product Information

A Fuel Injection Throttle Body is a component in a vehicle's fuel injection system that controls the amount of air entering the engine. It consists of a throttle plate that opens and closes based on the driver's accelerator pedal input. The throttle body plays a crucial role in regulating engine power and efficiency by managing the air-fuel mixture that enters the combustion chamber.

• Poor Acceleration or Hesitation: A malfunctioning throttle body can lead to poor acceleration or hesitation during driving, particularly when the driver presses the accelerator pedal. This can result from a stuck or faulty throttle plate that doesn’t open or close properly
• Rough Idle or Stalling: If the throttle body is dirty or malfunctioning, it may cause the engine to idle roughly or stall, especially when coming to a stop or during low-speed driving. This is often due to incorrect air-fuel mixture or air supply issues
• Check Engine Light: A faulty throttle body may trigger the Check Engine light. Diagnostic trouble codes (DTCs) related to the throttle position sensor or airflow may be stored in the vehicle’s system, indicating issues with the throttle body.

In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine VAG parts box and find an OEM branded part inside, simply with the addition of a VAG logo.
