Guidelines For Clean Working Conditions
WARNING: This page is about a different car, the 2018 Volkswagen Passat, 2017 Volkswagen Passat, and 2016 Volkswagen Passat. 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 "5 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.
- Only install clean parts: Remove the replacement parts from their packaging just before installing them. Do not use parts that have been loosely stored or unpackaged (for example, in tool boxes etc.).
- When the fuel system is open: Avoid working with compressed air if possible. Do not move the vehicle if at all possible.
