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  Genuine filter cartridges must always be used for the air filter.
t  The hose connections and hoses for charge air system must be free of oil and grease before fitting. Do not use silicone based lubricants when installing.
t  The air filter housing elements must be clean.
t  Secure all hose unions with hose clamps the same as those of the series → Spare parts catalogue.
t  Upon blowing the air filter housing with pressurised air take note of the following: To prevent malfunctions, cover all critical parts of the engine air intake tract such as air mass meter, intake pipes, etc. with a clean cloth.
t  Please observe requirements for disposal.
