Clean Working Conditions
Even a little contamination can lead to faults. When working on the fuel supply and fuel injection system, observe the following guidelines for a clean working environment:
- Before loosening, the connection points and surrounding areas must be cleaned thoroughly with engine or brake cleaner, and then cleaned area must be dried completely.
- Seal off any open lines and connections immediately with clean plugs, for example, taken from 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.
- 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 etc.).
- 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.
