Low oil warning that will not clear
A failed level sensor gives a false low oil warning, or no warning at all when the level is low. Dip the oil to check before replacing.
Fault codes
A level sensor fault code points to the sensor, its plug or the wiring.
Damaged float or lead
The float and lead sit in hot oil; a stuck float or chafed lead stops the sensor working.
Fitting tips
Drain the oil below the sensor first, fit a new gasket or O ring and refill to the correct level.
