Installing
Installation is in reverse order of removal, note the following:
For trouble-free function of the Mass Air Flow sensor, it is important to observe the following notes and perform the work procedures exactly.
‹› In the event the air filter element is severely contaminated or completely saturated, dirt particles or moisture may penetrate the MAF sensor and
falsify the measured air mass value. This results in a reduction of power, since a lower injection quantity is calculated.
‹› Always use an original equipment air filter element.
‹› Air filter housing must always be clean.
‹› Secure all hose connections with hose clamps appropriate for the model.
‹› Note the following when blowing out air filter housing with compressed air: To prevent malfunctions, cover critical air-flow engine components
such as Mass Air Flow (MAF) sensor, air duct pipes etc. with a clean cloth.
‹› Observe disposal regulations!
