Secondary air injection system

WARNING: This page does not describe the selected car, but rather 20 other vehicles, including the 2009 Volkswagen Golf, 2008 Volkswagen Golf, 2007 Volkswagen Golf, 2006 Volkswagen Golf, and 2005 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:

When performing repair work, especially due to the confined conditions in the engine compartment, pay attention to the following:

  • Route all types of lines (e.g. for fuel, hydraulics, EVAP system, coolant, refrigerant, brake fluid and vacuum) as well as electrical wiring so that the original positions are restored.
  • Ensure sufficient clearance to all moving or hot components.
