–Check the cleanliness of the air filter.
–Replace the filter if necessary.
–Check that the air inlet circuit is not blocked.
The turbocharging system must be perfectly sealed, from the exhaust manifold to the turbocharger, from the
turbocharger to the heat exchanger and from the heat exchanger to the throttle valve.
Check that there are no air leaks:
–around the turbocharger pressure sensor,
–around the air temperature sensor.
Check absence of leaks in the wastegate capsule pressure circuit connected to the turbocharger system.
Check that the air-air heat exchanger is not clogged (presence of oil).
If there is oil in the heat exchanger, the turbocharger is certainly damaged.
Using a pressure/vacuum pump, check that the turbocharger protection and turbocharging valve capsule
diaphragms do not leak.
Check the condition the motorised throttle valve in terms of clogging.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

* OCS: Oil Control System.
PR873OIL OXIDATION SIGNAL
(except D7F800 and D4F772)
PARAMETER
DEFINITIONThis parameter indicates the distance of the vehicle when the oil dilution threshold is
reached.
NOTESOnly apply the interpretation of this parameter if the OCS* strategy is activated on the
instrument panel. Check the configuration reading LC106 OCS on the instrument panel
computer is WITH.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant temperature
> 80˚C.
The oil condition is calculated by the oxidation program in the injection computer, according to the number of
engine revolutions.
When this count reaches a certain threshold before the end of the oil service period, the injection computer
sends a signal to the instrument panel, which will display service due. Parameter PR873 corresponds to
the vehicle mileage at the time this signal is sent.
Then the instrument panel computer deducts 900 miles (1500 km) before displaying the message Service required.
IMPORTANT:
When the message Service due appears on the instrument panel, the customer must have the oil changed within
the remaining 900 miles (1500 km).

AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
Repeat the conformity check from the start.
