Clean Working Conditions

NOTE:

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

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 the removed parts on a clean surface and cover them. Use a lint-free cloth.
Carefully cover or seal opened components if repairs are not performed immediately.
Only install clean components: Remove the replacement parts from their packaging just prior to installing them. 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.
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.
