Guidelines For Clean Working Conditions
Even small pieces of debris can cause faults. When working on the fuel supply and injection system, observe the following guidelines for 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 thoroughly dried.
- Immediately seal off any open lines and connections with clean plugs, for example taken from the 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.
- 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.
- Protect the disconnected connectors from dirt and moisture and only connect when they are dry.
