Parking/Auxiliary Heater And Fuel System Clean Working Conditions

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

• Thoroughly clean the connecting 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 will not be done immediately.
• Install only clean parts: remove the replacement parts from their packaging just before installing them. Do not use parts that have been stored loose (for example, in tool boxes etc.).
• When the system is open: do not work with compressed air.
• Do not move vehicle.
• Seal off any open lines and connections immediately with plugs, for example, take from :VAS6122  .
• Protect any disconnected connectors from dirt and moisture and connect them only when they are completely dry.
