Note  
The air mass value may be falsified due to excessive soiling  
or moisture. This would lead to a loss of power because a  
smaller injection quantity is calculated.  
Please observe disposal instructions!  
The cleaning is carried out according to a separate calcula‐  
tion.  
– Check for salt residue, dirt and leaves in air mass meter and  
air intake hose (engine intake side).  
– Check water drain hose in lower part of air filter housing for  
dirt and clogging.  
– Remove salt residues, dirt and leaves from upper and lower
