Removing
   
–  Detach air hose -2-.
–  Lift air cleaner housing -1- off ball studs.
–  Release hose clips -3- and -4- and remove air ducts.
Installing
  Note
If the air filter element is very dirty or wet, particles of dirt or water may reach the components and falsify the measured air mass value. This would lead to loss of power, since a smaller injection quantity is calculated.
Always use genuine part for air filter element.
A clean air filter housing is essential.
Before fitting the air filter housing, the ball pins on the intake manifold must be moistened with water without additives.
Hose unions and air intake pipes and hoses must be free of oil and grease before installation.
Use a silicone-free lubricant when installing air hoses.
Secure all hose connections with the same type of hose clips as original equipment → Electronic Parts Catalogue.
To prevent malfunctions, cover critical parts of the engine air intake (air pipes etc.) with a clean cloth when blowing out the air cleaner housing with compressed air.
Observe disposal regulations!
–  Extract salt residues, dirt or leaves from upper or lower part of air filter housing.
–  Blow out water drain with compressed air.
