2. Unplug electrical connector (2) at air mass meter G70.
3. Unbolt air cleaner (top section) (arrows) and take out air filter element. [Note: 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.Always use genuine part for air filter element.The air cleaner housing MUST be clean.Secure all hose connections with the correct type of hose clips (same as original equipment) Electronic parts catalogue.To prevent malfunctions, cover all critical parts of the engine air intake tract (air mass meter, intake pipes, etc.) with a clean cloth when blowing out the air cleaner housing with compressed air.Please observe requirements for disposal.]
4. Blow out water drain (small hole in bottom section of air cleaner) with compressed air.
