Guidelines For Clean Working Conditions
Even Very Small Particles of Dirt Can Cause a Fault. Observe the Following Guidelines for Cleanliness When Working on the Fuel System, Injection System and Turbocharger:
- Before loosening, the connection points and surrounding areas must be cleaned thoroughly with engine or brake cleaner, and then the cleaned area must be thoroughly dried.
- Immediately seal off any open lines and connections with clean plugs taken from the Engine Bung Set: VAS6122 , for example.
- 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.
- Only install clean parts: remove the replacement parts from their packaging just before installing them. Do not use any parts that have been kept out of packaging (for example, in a toolbox).
- 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.
