Clean Working Conditions

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, the connections and surrounding areas must be cleaned thoroughly with engine or brake cleaner, and then the cleaned area must be dried completely.

• Seal the open lines and connections immediately with clean plugs, for example, from the engine bung set (VAS 6122).

• Place removed parts on a clean surface and cover them with a lint free cloth.

• Carefully cover or seal, opened components if repairs are not performed immediately.

• Only install clean components: Only unpack replacement parts immediately prior to installation. Do not use parts that have been stored out of their original packaging (for example, in tool boxes etc.).

• If the system is open, do not work with compressed air and do not move the vehicle.

• Protect disconnected electrical connectors from dirt and moisture and only connect if dry.
