The bleed line fills with fluid.

If the bottle should become empty while performing the filling procedure, repeat the previous procedure.

-- Close the filling hose shut-off valve on the tank.

-- Close the vent hose shut-off valve on the bottle.

-- Disconnect the quick-release coupling from the bleed line and have the extra fluid flow into a container specially for that purpose.

-- If no more fluid flows out of the bleed line: Remove the AdBlue® Filling Tool VAS 6542 from the fuel tank filler neck.

-- Use a lint-free cloth soaked in water to clean the fuel tank filler neck and fuel cap.

-- Close the cap.

-- Take the bottle from the adapter plate and lay it on the floor.

-- Open the filling hose shut-off valve and drain any reducing agent still in the bottle.
