Guidelines For Clean Working Conditions

WARNING: This page is about a different car, the 2016 Audi A8 Quattro and 2015 Audi A8 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Even small pieces of debris can cause faults. When working on the fuel supply and fuel injection system, observe the following guidelines for a clean working environment:

Before loosening, the connection points and surrounding areas must be cleaned thoroughly with engine or brake cleaner, and then the cleaned area must be thoroughly dried.
Immediately seal off any open lines and connections with clean plugs taken from the Engine Bung Set :VAS6122 , for example.
Place removed parts on a clean surface and cover them with lint-free cloths.
Carefully cover or seal opened components if repairs are not performed immediately.
Only install clean parts: remove the replacement parts from their packaging just before installing them. Do not use parts that have been stored out of their original packaging (for example, in tool boxes).
If the 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, the fuel hoses must be cleaned again immediately.
Protect any disconnected connectors from dirt and moisture, and only connect them when they are completely dry.
