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.

SC035HIGH PRESSURE FUEL CIRCUIT FAULT FINDING
NOTESThis command is used to interpret the state of the high pressure fuel circuit (high
pressure pump, rail, injectors and high pressure supply pipes).
To run this command, select scenario SC035 on the diagnostic tool.
Procedure to be followed:
– select scenario SC035,
– follow the instructions then “confirm”,
– with the command in progress: do not operate on the vehicle,
– switch off the engine at the end of the test,
–the diagnostic tool displays the results,
– end of test.
Interpretation of correct results:
– If the results displayed are OK, the entire high pressure fuel circuit is in order. There is no need for any
operation.
