Throttle Body Replacement

Model: Audi A4 B6 - Years 2000-2004
Part: Throttle body

Cars have a mechanical component located within the fuel system that regulates the airflow into the combustion chamber. If this component fails, it will compromise the engine's functions. This component is the throttle body, and the following guide shows how to replace it. Perform the operation with the engine cold. Disconnect the electrical connectors from the throttle body and remove the intake hose. Typically, the throttle body has a long screw, a wing nut, and clips that secure the duct. Disassemble everything and disconnect the cables connected to the throttle body. Once done, you can remove it.
