Volkswagen Tiguan Throttle Body Replacement at your home or office.

How do mechanics replace the throttle body?

• The engine cover is removed, if necessary.
• The flexible rubber snorkel from the air filter housing to the throttle body is disconnected. Typically, the connection is made with a large stainless steel hose clamp.
• The electrical connections to the throttle body are removed.
• If the throttle body is not a drive-by-wire system, the accelerator cable and cruise control cable are disconnected and set aside.
• The bolts retaining the throttle body to the plenum, the gasket, and the throttle body are removed. If the throttle body is being cleaned and tested for re-use, approved chemicals are used in the cleaning process.
• The new or serviced throttle body is re-attached to the plenum and the bolts torqued to factory specifications.
• All cables and electrical connections are restored. The intake air snorkel is reconnected.
• If applicable, the electronic throttle installation and idle re-learn procedures are performed using an appropriate scan tool.
  
• Finally, the engine is started, brought to normal operating temperature, and idle speed is checked. The car is road tested to ensure normal operation and no illumination of warning or service lights.
