Clean Working Conditions

Even a little contamination can lead to faults. Observe the following guidelines for cleanliness when working on the fuel system, injection system and turbocharger:

• 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 plugs, for example, take from Engine Bung Set :VAS6122  .
• Place removed parts on a clean surface and cover them with lint-free cloths.
• Carefully cover or seal opened components if repairs are not performed immediately.
• Install only clean parts: Remove the replacement parts from their packaging just before installing them. Do not use parts that have been stored out of their original packaging (for example, in tool boxes etc.).
• If system is open, do not work with compressed air and do not move the vehicle.
• Make sure no fuel gets onto the fuel hoses. If necessary, wipe off the fuel hoses immediately.
• Protect the disconnected connectors from dirt and moisture and only connect when they are dry.
