Clean Working Conditions

WARNING: This page is about a different car, the 2008 Volkswagen R32. 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 area before disconnecting.
Place parts that have been removed on a clean surface and cover them. Use 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 tool boxes etc.).
When the system is open: Avoid working with compressed air if possible. Do not move vehicle unless absolutely necessary.
