WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2018 Audi S8, 2018 Audi A8 Quattro, 2017 Audi S8, 2017 Audi A8 Quattro, and 2016 Audi S8. However, it is still accessible from the selected car via links, so may be relevant.
Even small pieces of debris can cause faults. Observe the following guidelines for cleanliness when working on the fuel supply system, injection system and turbo charging system:
- Before loosening, thoroughly clean the connection points and surrounding areas with engine or brake cleaner, and then allow the cleaned area to dry completely.
- Immediately seal off any open lines and connections with clean plugs taken from the Engine Bung Set:VAS6122 , for example.
- Place the removed parts on a clean surface and cover them. Only use 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 outside of their packaging (for example, in tool boxes etc.).
- Do not work with compressed air when the system is open. Do not move the vehicle if at all possible.
- 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.
