Always clean the connection locations and the area around them before loosening.

Use lint-free cloths when cleaning. Audi recommends the "WYPALL X70/WORKHORSE" cloth made by Kimberly-Clark Professional.
Seal all open lines and connections immediately with clean plugs or caps from the Engine Bung Set VAS6122.
Place removed parts on a clean surface and cover them. Use foil or lint-free cloths.
Cover or plug unpacked components if repairs cannot be performed immediately.
Only install clean components: Install replacement parts immediately after removing them from their packaging.
Protect the disconnected connectors from dirt and moisture and only connect when they are dry.
