How to Remove and Replace the Throttle Body

Model: Audi Tt 8N, MK 1 - Years 1998-2006
Part: Throttle body

"The throttle body is a mechanical component located in the fuel system that regulates the airflow entering the carburetor or, in fuel-injected engines, the combustion chamber" (Wikipedia). It therefore controls the engine's RPM. First, open the hood and locate the throttle body, which in this case is found in front of the engine block, at the top, immediately after the radiator on the left side of the engine bay. Disconnect the air intake hoses and remove the bolts securing the throttle body in its housing. Once removed, disconnect the electrical connector secured by a clip. The maintenance operation shown in the images is performed on an Audi TT.
