Clean Working Conditions

WARNING: This page is about a different car, the 2006 Volkswagen Jetta and 2005 Volkswagen Jetta. 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 "6 rules" of cleanliness:

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 over opened components or seal, 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 (e.g. in tool boxes etc.).
When the system is open: Avoid working with compressed air if possible. Do not move vehicle unless absolutely necessary.
In addition, do not let diesel fuel flow onto coolant hoses. If necessary, the hoses must be cleaned again immediately. Replace corroded hoses.
