It is important to check the air filter maintenance minder periodically and service the air filter when recommended. The air filter minder monitors the vacuum in the intake and vacuum builds as the filter gets plugged. Vacuum can build enough so that it draws oil through the seals inside the turbocharger, damaging the seals.
