Installing
To ensure the proper function of the air mass meter it is important to observe the following notes and instructions.
  Note
t  If the air filter element is very dirty or wet, dirt or water could reach the air mass meter and affect the air mass value. This would lead to loss of power, since a smaller injection quantity is calculated.
t  Always use genuine part for air filter element.
t  Use silicone-free lubricant when fitting air intake hose.
t  Secure all hose connections with the correct type of hose clips (same as original equipment) → Parts catalogue.
–  Check for salt residue, dirt and leaves in air mass meter and air intake hose (engine intake side).
–  Check for dirt in air duct leading to air filter element. Clean salt residue, dirt and leaves out of top and bottom sections of air cleaner housing (wash out or vacuum out if necessary). Removing and installing air filter element → Chapter.
The remaining installation steps are carried out in the reverse sequence.
