Removing
-
Remove the bolts - arrows - from the upper section of the air filter housing.
-
Lift the upper section of the air filter housing and remove the air filter element.
Installing
Install in reverse order of removal, noting the following:
‹› If the air filter element is very dirty or soaked, dirt particles or moisture may have contaminated the MAF sensor and may be causing false mass air
flow values. This results in a reduction of power, since a lower injection quantity is calculated.
‹› Always use original equipment air filter insert
‹› Observe all disposal regulations!
‹› The air filter housing must be clean.
Note the following when cleaning the air filter housing with compressed air:
‹› To prevent malfunctions, cover critical air flow engine components such as the mass air flow sensor with a clean rag.
-
Check the mass air flow sensor and the intake hose (clean air side) for contamination.
-
Check the intake duct up to the air filter insert for contamination. If any contaminants are discovered, clean the air filter housing by washing or
vacuuming.
-
Remove and clean the snow screen - 1 -.
