WARNING: This page is about a different car, the 2021 Volkswagen GTI, 2020 Volkswagen GTI, 2019 Volkswagen GTI, 2018 Volkswagen Golf, and 2018 Volkswagen GTI. 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 connecting 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 will not be done immediately.
- Install only clean parts: remove the replacement parts from their packaging just before installing them. Do not use parts that have been stored loose (for example, in tool boxes etc.).
- If the system is open: do not work with compressed air. Do not move 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.
