t  Secure all hose connections with the correct type of hose clips (same as original equipment) → Parts catalogue.
t  To prevent malfunctions, cover all critical parts of the engine air intake tract (air mass meter, intake pipes, etc.) with a clean cloth when blowing out the air cleaner housing with compressed air.
–  Blow out water drain (small hole in bottom section of air cleaner) with compressed air.
–  Clean salt residue, dirt and leaves out of air cleaner housing (top and bottom sections); use a vacuum cleaner if necessary.
–  Check for salt residue, dirt and leaves in air mass meter and air hose (engine intake side).
–  Check for dirt and leaves in air duct going from lock carrier to air cleaner housing.
