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 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 any disconnected connectors from dirt and moisture, and only connect them when they are completely dry.
- Make sure no diesel fuel gets onto other components inside the engine compartment. Clean it off immediately if necessary.
