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.

–Particle filter regeneration failed: regeneration failed because the temperature upstream of the turbine is too
low. Apply Test 11 Temperature upstream of turbine too low.
In all cases, carry out the following operations:
– switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes) Communication
lost with computer: EDC16 CP33, check the tool connection and the computer supply,
– switch on the ignition and establish dialogue with the injection computer,
– run command SC036,
– depending on the operation carried out, select After particle filter regeneration with the diagnostic tool or
After particle filter replacement,
–switch off the ignition and wait for the diagnostic tool message (maximum wait 8 min): Loss of dialogue
with the computer: EDC16 CP33, check the tool connection and the computer supply voltage,
– then switch on the ignition again,
clear the present or stored faults from the computer memory (operation to be carried out within 3 minutes of
switching on the ignition).
Note:
Always change the engine oil and the oil filter in the following cases:
• following an After-Sales regeneration only if requested by a message on the CLIP diagnostic tool,
• after particle filter replacement following DF311 Number of failed regenerations exceeded,
– after a second regeneration (when two successive regenerations).

– That the diesel filter is not clogged.
– That there are no leaks on the high and low pressure diesel circuits: run Test 3 Low pressure circuit check.
–Test the high pressure fuel circuit:
Run scenario SC035 High pressure fuel circuit fault finding (see Interpretation of commands).
Continue by checking the following:
– The connection of the oil vapour rebreathing circuit.
– The pump pressure regulator (MPROP), (jamming - sticking); apply the interpretation of command AC226 Pump
pressure regulator.
– The rail pressure regulator (DRV), (jamming - sticking); apply the interpretation of command AC225 Rail
pressure regulator.
– Check the engine timing (and the position of the high pressure pump sprocket).
– Check the engine compressions: use a compression gauge, M9R hose end piece, part no. Mot. 1772 and apply
