Removing –  Loosen the engine cover at the locations -arrows- and remove.

–  Disengage the locking connection -arrows- and remove the air pipe -1-.

–  Separate the plug connection on the charge pressure control solenoid valve -N75--2-. –  Unscrew the bolt -1-. –  Remove all vacuum lines together with their brackets -arrows- upwards from the air filter. –  Place charge pressure control solenoid valve -N75- with vacuum hoses on engine.

–  Unplug connector -3- from air mass meter -G70-. –  Remove the air intake hose, and release the hose clip -2-. –  Version for cold climate zones: Remove air hose; loosen hose clip -1- for this. –  Unscrew the bolt -4- and remove the air filter housing. Remove suction hose   Note As it is difficult to gain access to clip on suction hose, it is better to remove intake connecting pipe from turbocharger.

Installing Installation is carried out in reverse order, noting the following:   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  In order to avoid functional problems, you should cover the critical air-conducting components such as air mass meter, air pipes etc. with a clean cloth when blowing out the air filter housing with compressed air. t  Hose connections and air pipes and hoses must be free from oil and grease before fitting. t  Use a silicone-free lubricant when installing the air hoses. t  Secure all hose connections with the correct type of hose clips (same as original equipment) → Electronic parts catalogue. –  Check suction hose (engine intake side) for salt residue, dirt and leaves and, if necessary, clean. –  Check air duct leading from lock carrier to air filter housing for dirt and leaves. Clean if necessary. Remaining assembly is performed in reverse sequence.
