Installing

Installation is in reverse order of removal, note the following.

For trouble-free function of the Mass Air Flow (MAF) sensor, it is important to observe the following notes and perform the work procedures exactly.

• Replace O-ring.

• 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.

• Use a silicon-free lubricant to install the air duct hose.

• Secure all hose connections using hose clamps appropriate for the model type.

- Check Mass Air Flow (MAF) sensor and air duct hose (clean air side) for salt residue, dirt and leaves.

- Check the air duct up to the air filter element for dirt. Clean air filter housing (upper and lower sections) of salt residue, dirt or leaves (wash out or use vacuum cleaner if necessary).
