| Pull air cleaner housing (top section) out of retainer and move it clear towards engine. |
| –
| Take out air filter element. |
| To ensure the proper function of the air mass meter it is important to observe the following notes and instructions. |
Note | t
| If the air filter element is very dirty or wet, dirt or water could reach the air mass meter and affect the air mass value. This would lead to loss of power, since a smaller injection quantity is calculated. |
| t
| Always use genuine part for air filter element. |
| t
| Hose connections and hoses for charge air system must be free of oil and grease before assembly. Do not use any lubricants containing silicone when assembling. |
| t
| The air cleaner housing MUST be clean. |
| t
| Secure all hose connections with the correct type of hose clips (same as original equipment) → Parts catalogue. |
| t
| To prevent malfunctions, cover all critical parts of the engine air intake tract (air mass meter, intake pipes, etc.) with a clean cloth when blowing out the air cleaner housing with compressed air. |
| t
| Please observe requirements for disposal. |
| –
| Blow out water drain (small hole in bottom section of air cleaner housing) with compressed air. |
| –
| Clean salt residue, dirt and leaves out of air cleaner housing (top and bottom sections); use a vacuum cleaner if necessary. |
| –
| Check for salt residue, dirt and leaves in air mass meter and air intake hose (engine intake side). |
| –
| Check for dirt and leaves in air duct going from lock carrier to air cleaner housing. |
| –
| When installing the air filter element, check that it is properly centred in the retainer in the air cleaner housing (bottom section). |
| –
| Fit the top section of the air cleaner housing carefully on the bottom section, without using force. Make sure the top section of the air cleaner housing is fitted straight on the air filter element (note position of sealing lip on air filter element). |
| –
| Ensure secure fit of intake hose at air mass meter -G70-. |
| The remaining installation steps are carried out in the reverse sequence. |
