📋 Procedure

1. Remove cover above radiator grille (4 bolts).
2. Completely remove air duct (1).
3. Unplug electrical connector (2) at air mass meter G70.
4. Release hose clip (3) and detach air hose from air mass meter G70.
5. Remove bolts (arrows) from air cleaner (top section) and lift out air cleaner (top section).

6. Disconnect vacuum hose (1) at air filter bypass flap valve N275 (if fitted) (2).
7. Release retainer for bottom section of air cleaner (press in rubber on left and right side and pull upwards).
8. Unplug electrical connector at air filter bypass flap valve N275 (if fitted). [Note: The air filter bypass flap valve N275 is not installed on certain equipment versions or on certain country-specific versions.Electrical connector (2) for air filter bypass flap valve N275 is located at side of air cleaner housing.]
9. Carefully take out air cleaner (bottom section). [Note: 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.Always use genuine part for air filter element.Use a silicone-free lubricant when installing the intake hose.Secure all hose connections with the correct type of hose clips (same as original equipment) Electronic parts catalogue.Do not use lubricant when installing retainer.]
10. If hot air intake is fitted (for countries with cold climates only), make sure that air intake connection has engaged properly (arrows) (pay attention to markings).
11. Check water drain hose (arrow) in air cleaner (bottom section) for dirt and other obstructions (clean if necessary).
12. Clean salt residue, dirt and leaves out of air cleaner housing (top and bottom sections); use a vacuum cleaner if necessary.
13. Check for salt residue, dirt and leaves in air mass meter and air intake hose (engine intake side).
14. Check for dirt in air duct leading to air filter element.
15. Plug in electrical connector at air filter bypass flap valve N275 again.
16. Re-install air cleaner (bottom section). [Note: The water drain hose must be routed straight downwards and must not be kinked.]
17. Slide vacuum hose (1) back onto connection of air filter bypass flap valve N275.
18. Lug on air filter element (1) must make contact with lug on air cleaner housing (2).
19. Fit the top section of the air cleaner carefully on the bottom section, without using force. [Note: Before tightening bolts, make sure that top section of air cleaner is inserted into groove on bottom section of air cleaner (to prevent air leaks).]
20. Then screw top section of air cleaner back onto bottom section.
21. Ensure secure fit of air hose at air mass meter G70.
22. Re-connect electrical connector at air mass meter G70.
23. The remaining installation steps are carried out in the reverse sequence.
