Guidelines For Clean Working Conditions
WARNING: This page is about a different car, the 2024 Audi SQ7 and 2023 Audi SQ7. 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, turbocharging system and injection system:
- 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.
- Before removal of the fuel injectors/injectors clean their surroundings throughly and if necessary blow out using compressed air, to do this wear protective eyewear.
- Immediately seal off any open lines and connections with clean plugs, for example from the Engine Bung Set:VAS 6122 .
- 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 any parts that have been kept out of packaging (for example, in a toolbox).
- 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 the disconnected connectors from dirt and moisture and only connect when they are dry.
