NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
– the special regenerate particle filter warning light is lit or a warning message is
displayed on the instrument panel.
– The vehicle needs to be driven specially to activate particle filter regeneration during
driving.
Priorities when dealing with a number of faults:
Firstly, deal with the following faults:
– DF308 Particle filter clogged if it is present or stored.
– DF311 Failed regenerations limit exceeded if it is present.
– DF315 Particle filter diff* pressure sensor if it is present or stored.
The fault appears after:
– 7 failed regeneration attempts when driving and the weight of soot in the particle filter is greater than
21 g.
– the weight of soot in the particle filter is greater than 58 g.
PART A:
The flow chart on the following page can be used to analyse the driving profile and causes of the activation of this
fault.

Check the status of the differential pressure sensor connector and engine management computer.
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the particle filter is present.
If it is present,
Visually check that the particle filter is in good condition by positioning the vehicle on a lift:
– not damaged (no abnormal welds, if necessary compare it with another vehicle fitted with particle filter),
– if there are After-Sales sleeves, as a result of a previous operation, check that the particle filter's contents were
not emptied out when it was removed.
If the particle filter is not in good condition or is absent:
– Replace the particle filter.
– Switch on the ignition.
– establish dialogue with the injection computer,
– run command SC036 Reinitialise programming,
–select After particle filter replacement as the operation type, then follow the instructions given by the
diagnostic tool,
– switch off the ignition,
– wait for the diagnostic tool message (maximum time 8 minutes): Communication lost with computer:
EDC16C36, check the tool connection and computer supply before switching the ignition back on.
– clear the faults from the computer memory (this operation must be carried out within 3 minutes of the ignition
being switched on).
– Check the weight of soot: PR383 Weight of soot in the particle filter.
– If PR383
≥ 1 g. Apply the procedure of test 12 Manual clearing of the weight of soot.
If the fault is still present, contact the Techline.

PR383 < 70 g.
If the weight is greater than 70 g carry out an After-Sales regeneration.
Check that there are no leaks or blockages in the exhaust pipe,
