Installing
To ensure the proper function of the air mass meter -G70- it is important to observe the following 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
