DEFINITIONThese parameters are shown in Km.
NOTESSpecial notes:
Interpret these parameters only if DF312 Speed request is present or stored.
Conformity check with the engine stopped and the ignition on, or with the engine running and the engine
coolant temperature > 80°C
These parameters are used so that the history of the last ten regeneration failures when driving are known.
For VDIAG 58, 18, 1C
Each of these parameters contains the vehicle mileage during a failed particle filter regeneration when driving.
Each parameter relates to an engine status. The statuses and parameters are recorded at the same time
(for example PR797 is associated with ET709 Engine status record no. 4).
Each new recorded value is saved under the next PR (PR+1).
When all ten parameters have a value other than zero and there is a regeneration failure when driving, the
mileage information for PR794 is cleared and replaced with the new value.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

WEIGHT OF SOOT AFTER REGENERATION
PARAMETER
DEFINITIONThis parameter indicates the weight of soot in g present in the particle filter after
a regeneration.
NOTESThis parameter is to be consulted after using SC017 Particle filter regeneration.
Conformity check with the engine stopped and ignition on, or the engine running and engine coolant
temperature > 80°C, without electrical consumers
If PR1012 is less than 15 g, the particle filter regeneration completed correctly.
If PR1012 is greater than 15 g, a second particle filter regeneration must be performed 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 perform a routine oil change before a second After-Sales regeneration (see SC017 Particle filter
regeneration).
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

DESCRIPTION OF THE PROCESS
particle filter regeneration takes place in 3 stages (values given as a guide only):
–Warm-up phase: the engine speed is fixed or varies between 1000 rpm and 1650 rpm.
This phase lasts at least 3 minutes, until the coolant temperature exceeds 80°C.
–Regeneration phase: the engine speed is fixed or varies between 1000 rpm and 1650 rpm. Engine injection
is retarded. The exhaust fumes rise in temperature and burn the soot retained in the particle filter. The particle
filter downstream temperature starts to rise after the particle filter upstream temperature due to the
volume of the particle filter. Then the combustion of the soot stored in the particle filter causes the particle filter
downstream temperature to increase, possibly reaching more than 700°C depending on the amount of soot in
the filter (with a particle filter upstream temperature of approximately 600°C). This phase lasts between 20
and 25 minutes.
–Cooling phase: the engine speed is fixed or varies between 1000 rpm and 1650 rpm.
Engine injection returns to normal and the exhaust gases cool the particle filter.
This phase lasts 3 minutes. At the end of this period, the engine speed returns to idle speed or remains fixed at
1500 rpm.
The process lasts at least 30 minutes (regeneration time will be increased depending on how long it takes for
the coolant temperature to reach 80°C).
CONFIRMING 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 PR1012 is less than 15 g, the particle filter regeneration
completed correctly. If PR1012 is greater than 15 g, a second particle filter regeneration must be performed using
the command in the diagnostic tool and choose 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 systematically change the engine oil before a second After-Sales regeneration.
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 back-pressure. Deal with any faults that appear or replace the particle filter.
Run command SC036 Reinitialise programming and select After particle filter replacement.
Check the weight of soot: PR383 Weight of soot in the particle filter.
If PR383
≥ 1 g. Apply the procedure for test 8 Manual clearing of the soot weight.

ALP 2 Starting difficult (or impossible)
NOTESBefore dealing with this customer complaint, check that there are no faults, and
the conformity (or otherwise) of the parameters and statuses using the
diagnostic tool.
If the customer complaint is not eliminated, perform the following checks.
Is it difficult or impossible to start the engine?
PART A:
Check the engine earths.
Ensure that the engine speed reaches 250 rpm with the starter motor, as displayed on the parameter screen (PR055
Engine speed).
If the engine speed is less than 250 rpm, refer to Technical Note 6014A, Checking the charging circuit.
If the engine speed shown on CLIP is zero and the engine is running, check the resistance of the engine speed
sensor between connections 3BG and 3BL of component 149:
Replace the sensor if its resistance is not 510 Ω < X < 850 Ω at 20°C
Check the continuity of the following connections:
– connection codes 3BG and 3BL between components 120 and 149.
Check the conformity of the engine earths (oxidation, tightness, etc.).
Check the mounting, the gap (if necessary refer to the information in the workshop repair manual for the vehicle) and
the condition of the sensor (overheating).
Replace if necessary.
Check the synchronisation of the camshaft sensors and the engine speed sensors with the display of ET238
Synchronisation.
If synchronisation is not active, refer to the checks described in DF195 Camshaft/engine speed consistency.
check the fuel circuit sealing.
If the fault is still present, see DF053 Rail pressure regulation function 2.DEF, step 4.
Check that the heater plugs are actuated using the AC001 Preheating unit command.
Check the sealing and condition of the inlet circuit: run Test 4 Turbocharged air inlet circuit check and follow the
associated fault finding procedure.
Check that there are no foreign bodies on the flowmeter grille: run Test 5 Air flowmeter and follow the associated
fault finding procedure.
Check the position of the exhaust gas recirculation valve.
Check that the exhaust is not blocked: run Test 1 Exhaust pipe check and follow the associated fault finding
procedure.
Check the consistency of the signal from the engine coolant temperature sensor.
Check the operation of the pressure regulator (see AC011 Rail pressure regulator).
Check the operation of the injectors (excessive return leak, clogging, seizing): run Test 9 Poor injector operation.
Check the engine timing (and the position of the high pressure pump sprocket).
Check the balance of the compressions, according to the power consumption during the starting phase
(Compression test menu on the CLIP Technic tool or using a compression gauge)
after the operation, clear the faults caused by disconnecting the regulator and the heater plugs.
End of part AImpossible
