Guidelines For Clean Working Conditions

NOTE:

Even small pieces of debris can lead to faults. Therefore when working on the fuel supply, injection system and turbocharger, pay careful attention to the following rules of cleanliness:

Before loosening, the connection points and surrounding areas must be cleaned thoroughly with engine or brake cleaner, and then the cleaned area must be dried completely.
Immediately seal off any open lines and connections with clean plugs, for example, taken from the 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 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).
If the 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, the fuel hoses must be cleaned again immediately.
Protect any disconnected connectors from dirt and moisture, and only connect them when they are completely dry.
