Installing
To ensure the proper function of the air mass meter -G70- 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 -G70- 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 a silicone-free lubricant when installing the intake hose.
t  Secure all hose connections with the correct type of hose clips (same as original equipment) → Parts catalogue
–  Check water drain hose in air cleaner housing (bottom section) for dirt and leaves (use a vacuum cleaner if necessary).
–  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 intake hose (engine intake side).
–  Check for dirt in air duct leading to air filter element.
–  When installing the air filter element, check that it is properly centred in the retainer in the air cleaner (bottom section).
