Installing
For the air mass gauge to work properly, respect the instructions and work procedures which are described below.
  Note
t  Renew O-ring.
t  If the air filter element is very dirty or wet, the air mass gauge could get dirty with dust particles or get wet and therefore the readings will be incorrect. This would lead to loss of power, since a smaller injection quantity is calculated.
t  Always use original parts.
t  Do not use a silicone based lubricant when fitting the air duct hose.
t  Secure all hose connections with the correct hose clips (original parts) → ETKA (Electronic parts catalogue).
–  Check that there are no salt residues, dirt or leaves in the air mass gauge, or in the air duct hose (clean air side).
–  Check that there is no dirt between the air duct and the air filter element. Check that there are no salt residues, dirt or leaves in the air filter housing (top and bottom); clean with a vacuum cleaner if necessary. Air filter cartridge: Removing and installing → Chapter.
Perform remaining installation in reverse order of removal.
