If regeneration whilst driving has not been possible, the driver should request After-Sales regeneration in the
following cases:
– the soot weight is greater than 56 g for Vdiag 18.
– the soot weight is greater than 59 g or the number of failed regenerations is greater than 10 for Vdiag 1C
and 20.
This regeneration is carried out in the workshop. It is essential to follow the instructions described in the
interpretation of commands SC017 Particle filter regeneration. To carry out regeneration safely (see Te c h n i c a l
Note 5040A, Recommendations for particle filter regeneration).
Warning light management:
Instrument panel display
The computer manages the data display on the instrument panel relating to engine operation. This involves six
functions:
– the pre-postheating warning light,
– the coolant temperature warning light or warning message;
– the level 1 fault warning light (non-critical fault),
– the level 2 fault warning light (emergency stop),
– the OBD warning light (European On Board Diagnostic),
– particle filter warning message or light.
These six functions are represented by 4 or 5 warning lights and/or messages displayed by the trip computer.
In addition, for vehicles fitted with a voice synthesiser the illumination of some warning lights may be accompanied
by a spoken message (refer to the Driver's Handbook for the vehicle concerned).
A 3 second visual inspection (automatic test procedure managed by the instrument panel) is carried out by the
injection computer when the ignition is switched on.
Orange pre-post heating/non-critical fault SERVICE warning light (level 1)
This light is used both as an in-operation indicator light and as a system fault indicator:
– Continuously lit with + after ignition feed:
Indicates plug preheating (this light goes out when preheating is complete and the engine is able to start).
– Continuously lit accompanied by the message Check injection or Electronic fault:
Indicates a level 1 fault (involving operation of the injection system in defect mode).
The driver should carry out repairs as soon as possible. IMPORTANT
The particle filter must be replaced after a period of time which largely depends on the grade of engine oil used.
This information is provided in the vehicle's Driver's handbook.
After replacing the particle filter, it is essential to reconfigure certain parameters in the computer (see SC036
Reinitialise programming).
