Guidelines For Clean Working Conditions
WARNING: This page is about a different car, the 2015 Volkswagen Touareg. However, it is still accessible from the selected car via links, so may be relevant.
When working on the fuel supply/injection system, pay careful attention to the following "rules" of cleanliness:
- Thoroughly clean the connection points and the surrounding area before loosening.
- Place the removed parts on a clean surface and cover them. Only use lint-free cloths.
- Carefully cover or seal opened components if the repair is 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 loosely stored or unpacked (for example, in tool boxes etc.).
- If the system is open: do not work with compressed air. Do not move the vehicle.
- Make sure no fuel gets onto the fuel hoses. If necessary, wipe off the fuel hoses immediately.
- Protect any disconnected connectors from dirt and moisture and connect them only when they are completely dry.
