Clean Working Conditions

WARNING: This page is about a different car, the 2009 Volkswagen GTI and 2008 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" :

Thoroughly clean all connections and the surrounding areas before disconnecting.
Place parts that have been removed on a clean surface and cover them using lint free cloths.
Carefully cover or seal opened components, if repairs are not performed immediately.
Only install clean components: Only unpack replacement parts immediately prior to installation. Do not use parts that have been stored loose (for example, in a tool box, etc.).
When the system is open: Avoid working with compressed air if possible. Do not move the vehicle unless absolutely necessary.
