Clean Working Conditions

Even very small particles of dirt can cause a fault. When working on the fuel supply and fuel injection system, observe the following guidelines for a clean working environment:

• Before loosening, connections and surrounding areas must be cleaned thoroughly with engine or brake cleaner, and then cleaned area must be dried completely.
• Seal off any open lines and connections immediately with clean plugs, for example, taken from Engine Bung Set VAS6122.
• 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.
• Only install clean parts: remove replacement parts from the packaging immediately prior to installation. Do not use parts that have been stored outside of their original packaging (for example in tool boxes etc.).
• When the system is open: do not work with compressed air. Do not move vehicle unless absolutely necessary.
• Protect the disconnected connectors from dirt and moisture and only connect when they are dry.
