Parking/Auxiliary Heater And Fuel System Clean Working Conditions

WARNING: This page is about a different car, the 2016 Volkswagen Beetle, 2015 Volkswagen Beetle, 2014 Volkswagen Beetle, and 2013 Volkswagen Beetle. However, it is still accessible from the selected car via links, so may be relevant.

Follow these five "rules" when working on the fuel supply/injector system:

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.).
When the system is open: do not work with compressed air.
Do not move vehicle.
Seal off any open lines and connections immediately with plugs, for example, take from Engine Bung SetVAS6122.
Protect any disconnected connectors from dirt and moisture and connect them only when they are completely dry.
