• Always clean the connection locations and the area around them with engine or brake cleaner before loosening. The always dry the cleaned location.
• 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 out of their original packaging (for example, in tool boxes etc.).
• Do not work with compressed air when the system is open. Do not move the vehicle if possible.
• Protect any disconnected connectors from dirt and moisture, and only connect them when they are completely dry.
