Guidelines For Clean Working Conditions On Parking/Auxiliary Heater And Fuel System

Special tools and workshop equipment required 

• Engine Bung Set:VAS6122 

Follow these "rules" when working on the fuel supply/injection system:

• Thoroughly clean the connection points and the surrounding area before loosening.
• Place the removed parts on a clean surface and cover them. Only use lint-free cloths.
• Carefully cover or seal opened components if the repair is not performed immediately.
• Only install clean parts: remove the replacement parts from their packaging just before installing them. Do not use parts that have been loosely stored or unpackaged (for example, in tool boxes etc.).
• Do not work with compressed air when the system is open.
• Do not move the vehicle.
• Immediately seal off any open lines and connections with clean plugs, for example, taken from the :VAS6122  .
• Protect any disconnected connectors from dirt and moisture, and only connect them when they are completely dry.
