Even a Little Contamination Can Lead to Faults. Observe the following Guidelines for Cleanliness When Working on the Fuel System, on the Injection System and on the Charging System:
- Before loosening, connections 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 plugs, for example, take 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 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, wipe off the fuel hoses immediately. Replace any corroded fuel hoses.
- Protect the disconnected connectors from dirt and moisture and only connect when they are dry.
