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).

COMPUTER REPLACEMENT OR REPROGRAMMING
Two operations must be performed when replacing or reprogramming the computer:
SC003 Save computer data and SC001 Enter saved data.
– Run command SC003 Save computer data before replacing or reprogramming the computer. This enables
certain data to be saved in the diagnostic tool so that the new computer* can be reconfigured like the old one.
The saved data includes: injector codes, EGR programming, specific data for particle filter operation and vehicle
options.
– Run command SC001 Write saved data after replacing or reprogramming the computer. This command
enables the data (saved by the command SC003 Save computer data) to be rewritten in the new computer*.
If you cannot establish dialogue with the computer being replaced: you will not be able to save anything.
After replacing the computer:
– Manually enter the IMA codes for each injector by reading the code on each injector (see 13B, Diesel injection,
Replacement of components, Injector replacement).
– Enter the data specific to particle filter operation by running SC036 Reinitialise programming and select After
replacing the injection computer with no save option.
Exhaust gas recirculation valve data is programmed automatically the 1st time the new computer is switched on*.
* New computer or reprogrammed computer.
Specific to the cruise control/speed limiter operation to be carried out before reprogramming of the
computer:
Before reprogramming the injection computer, move the main cruise control/speed limiter switch to the rest
position. The information about the cruise control or the speed limiter displayed on the instrument panel
disappears.
Otherwise, if the main switch remains in the cruise control or speed limiter position during and after reprogramming,
the Cruise control/Speed limiter function will not be operational.
The procedure for resetting the function is as follows:
– Vehicle ignition on.
– Position the cruise control/speed limiter switch in the rest position (the computer then detects the rest position).
– Position the cruise control/speed limiter switch in the Cruise control position to activate the Cruise control
function.
– Position the cruise control/speed limiter switch in the Speed limiter position to activate the Speed limiter function. IMPORTANT
– Switch on the diagnostic tool (mains or cigarette lighter supply).
– Connect a battery charger.
– Cut off all the electrical consumers (lights, interior lighting, air conditioning, radio CD, etc.).
– Wait for the engine to cool (engine coolant temperature < 60° and air temperature < 50°).
– For Vdiags 50, 58, 5C, during (re)programming of the computer, the engine fan assemblies are actuated
automatically.
– For Vdiags 18, 1C, 20, during (re)programming of the computer, the instrument panel screen displays
“Oil pressure fault”.
– Ignore this message and do not take any action in connection with it.

REPLACING OR CLEANING THE EXHAUST GAS RECIRCULATION (EGR) VALVE
After the exhaust gas recirculation valve has been replaced, the computer must store the new valve offset and the
offset measured when the ignition was last switched off, which corresponds to the valve closing.
Using this data, the computer can detect whether the valve is clogged or seized.
When the valve is replaced or cleaned, clear the stored offsets so that the program uses the new valve's offset
value.
The data linked to this strategy is compiled in the Antipollution/OBD sub-function.
– PR128 First EGR valve offset.
– PR129 Last EGR valve offset > or = PR128 for a new valve.
The PR128 and PR129 programming must be cleared every time the exhaust gas recirculation valve is replaced.
PROCEDURE:
– Run command SC036 Reinitialise programming.
–Select EGR valve as the type of operation, then follow the instructions given by the diagnostic tool.
When the command is finished,
– switch off the ignition,
–wait 1 minute before switching on the ignition again.
When the ignition is switched on again, the new EGR valve offset is automatically reprogrammed.
– start the vehicle to enable the latest EGR valve offset to be programmed,
– switch off the ignition,
–wait 1 minute before switching on the ignition again.
Reprogramming of the last EGR valve offset is stored in the computer.
– then check the system faults, and clear any stored faults,
– otherwise, deal with the faults that are present and clear the faults in the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
End of operation.Note:
When the reinitialisation is complete, the Emission control/OBD sub-function displays:
PR128 = PR129 > 100 %
Note:
When the new EGR valve offset has been reprogrammed, the Emission control/OBD sub-function displays:
10 % < PR128 < 40 %
PR129 > 100 %
Note:
When the last EGR valve offset has been reprogrammed, the Emission control/OBD sub-function displays:
10 % < PR128 < 40 %
10% < PR129 < 40%
