PR383WEIGHT OF SOOT IN PARTICLE FILTER
PARAMETER
DEFINITIONThis parameter indicates the weight of soot in the particle filter in g.
NOTESNone.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
The value of the weight of soot in the particle filter must be:
PR383 < 56 g.
If the weight is greater than 56 g:
For all Vdiags (except 18): carry out an After-Sales regeneration. Run command SC017 Particle filter
regeneration and follow the procedure (see Interpretation of commands).
For Vdiag 18:
Reprogram the computer in Vdiag 1C.
Then apply the procedure corresponding to Vdiag 1C.
In the event of a fault, refer to the interpretation of fault DF315 Particle filter diff* pressure sensor.

PR1012WEIGHT OF SOOT AFTER REGENERATION
STATUS
DEFINITIONThis parameter indicates the weight in g of soot present in the particle filter following
regeneration.
NOTESThis parameter should be consulted after running SC017 Particle filter regeneration.
Conformity check: Engine stopped and ignition on, or engine running and engine coolant
temperature > 80°C without electrical consumers
If this parameter is less than 15 g, particle filter regeneration was successful.
If PR1012 is greater than 15 g, it is necessary to perform a second particle filter regeneration using command
SC017 Particle filter regeneration.
IMPORTANT:
Before performing a second After-Sales regeneration of the particle filter, the engine must be allowed to cool down
for 2 hours with the bonnet open.
Do not carry out an engine oil change before a second After-Sales regeneration.

VALIDATING THE REGENERATION PROCESS:
At the end of regeneration, a message appears to announce whether the regeneration was successful:
•Particle filter regeneration finished:
Consult PR1012 Weight of soot after regeneration. If this parameter is less than 15 g, the particle filter
regeneration was successful. If PR1012 is greater than 15 g, it is necessary to carry out a second particle filter
regeneration using the diagnostic tool and run command SC017.
IMPORTANT:
Before performing a second After-Sales regeneration of the particle filter, the engine must be allowed to cool
down for 2 hours with the bonnet open.
Do not carry out an engine oil change before a second After-Sales regeneration.
For Vdiag 28 and 62:
Change the engine oil if requested by a message on the instrument panel.
For the other VDiag:
Consult PR848 Number of regeneration failures. If PR848 is greater than 3, change the engine oil.
Particle filter too full - replace the particle filter: regeneration has failed. The weight of soot in the particle filter
is so great that it is creating a counter pressure. Deal with any faults that appear or replace the particle filter. Run
command SC036: Reinitialise programming and select After particle filter replacement.
For Vdiag 28 and 62:
Change the engine oil if requested by a message on the instrument panel.
For the other Vdiags:
Consult PR848 Number of regeneration failures. If this parameter is greater than 3, it is essential to
change the engine oil.

TEST12 Diesel fuel conformity check
WARNING
During this operation, it is essential to:
– refrain from smoking or bringing incandescent objects close to the work area,
– guard against petrol splashes caused by the residual pressure in the pipes,
– wear safety goggles with side guards,
– wear leaktight gloves (Nitrile type).
IMPORTANT
– To avoid any corrosion or damage, protect the areas on which fuel is likely to run.
– To prevent impurities from entering the circuit, place protective plugs on all fuel circuit components
exposed to the open air.
Preparations:
Weigh an empty 1300 ml plastic cup (part no. 77 11 171 413) with its cover (part no. 77 11 171 416) using
electronic scales such as those used in body paint workshops (example: PANDA part no. 77 11 224 995). Record
the weight of the empty plastic cup.
This type of plastic cup is used to prepare paint.
Remove 1 litre of fuel from the diesel fuel filter outlet (see MR395 (Laguna II ph2) or MR402 (Vel Satis ph2)
or MR405 (Espace IV ph2) or MR364 (Mégane II ph2) or MR370 (Scénic II ph2), Mechanical, 19C, Tank, Fuel
tank: Draining), using a pneumatic transfer pump (part no. 634-200) and place it in the 1300 ml plastic cup.
Cover the plastic cup with its cover and let it settle for approximately2 minutes.
Is the fuel cloudy or does it
separate into two parts?Presence of water in diesel fuel, the fuel is not compliant.
Drain the fuel circuit, including the tank (see MR395 (Laguna II
ph2) or MR402 (Vel Satis ph2) or MR405 (Espace IV ph2) or
MR364 (Mégane II ph2) or MR370 (Scénic II ph2), Mechanical,

If the fuel weight is less than the minimum value then there is petrol
in the diesel fuel.
If the fuel weight is greater than the minimum value then there is oil
in the diesel fuel.

Note:
If the weight measured reaches the limit values, the measurement can be performed with a 2230 ml plastic cup
(part no. 77 11 171 414) and its cover (part no. 77 11 171 417):
– Carry out a quick test drive in order to mix the fuel, then remove 2 l of fuel.
– Perform the test again and check the results by multiplying the limit values by 2.
