Clean Working Conditions

WARNING: This page is about a different car, the 2009 Audi TT and 2008 Audi TT. However, it is still accessible from the selected car via links, so may be relevant.

Even a little contamination can lead to faults. Observe the following guidelines for cleanliness when working on the fuel system, injection system and turbocharger:

Before loosening, connections and surrounding areas must be cleaned thoroughly with engine or brake cleaner, and then the cleaned area must be dried completely.
Seal the open lines and connections immediately with clean plugs, for example, from the engine bung setVAS 6122.
Place removed parts on a clean surface and cover them with 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 out of their original packaging (for example in tool boxes etc.).
If system is open, do not work with compressed air and do not move the vehicle.
Make sure no fuel gets onto the fuel hoses. If necessary, wipe off the fuel hoses immediately. Replace any corroded fuel hoses.
Protect disconnected electrical connectors from dirt and moisture and only connect if dry.
