OIL DILUTION SIGNAL
PARAMETER
DEFINITIONThis parameter indicates the vehicle mileage when the oil dilution threshold is reached.
NOTESThis parameter should be interpreted only if the OCS (Oil Control System) program
is activated on the instrument panel. On the instrument panel computer, check the
configuration reading LC106 O.C.S: WITH.
Except Vdiag 44, 45 and 49.
Conformity check: Engine stopped and the ignition on, or the engine running and the engine coolant
temperature > 80°C, without electrical consumers
The injection computer assesses the dilution rate of the engine oil according to the customer's driving style.
When the dilution level reaches a certain threshold before the end of the oil change interval, the injection
computer sends a signal to the instrument panel, which then displays Service required. Parameter PR875
corresponds to the vehicle mileage at the time this signal is sent.
IMPORTANT
When the message Service required appears on the instrument panel, the customer must arrange an immediate
oil change to prevent damage to the engine.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
