| Unplug electrical connector -1- at air mass meter -G70-. |
| –
| Release hose clip securing air hose (coming from turbocharger) and disconnect hose from air mass meter -G70-. |
| –
| Unscrew both bolts from air mass meter -G70-. |
| –
| Then carefully pull air mass meter -G70- out of guide on air cleaner housing. |
| To ensure that the air mass meter -G70- functions properly, 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
| Use a silicone-free lubricant when installing the air hoses. |
| –
| Check for salt residue, dirt and leaves in air mass meter and air intake hose (engine intake side). |
| –
| Check for dirt in air duct leading to air filter element. If necessary, clean salt residue, dirt and leaves out of air cleaner housing (top and bottom sections); wash out or use a vacuum cleaner as required. Removing and installing air cleaner → Chapter. |
