After-Sales regeneration comprises 4 important stages:
– Heating of the engine and checking for a small quantity of soot in the particle filter by measuring the differential
pressure.
– The system changes from combustion mode and starts to regenerate the particle filter. Gradual cooling of the
particle filter.
– End of After-Sales regeneration.
Stopping conditions:
– Dialogue with the diagnostic tool has been lost.
– Vehicle movement detected by speed sensor.
– Brake or clutch pedal depressed.
– Stop regeneration requested by the diagnostic tool.
– End of test.
The procedure lasts 30 minutes.
– At the end of regeneration, a message announces whether the regeneration has been successful or which
operations to carry out.
CONFIRMING THE REGENERATION PROCESS:
At the end of regeneration, a message appears to announce whether the regeneration was successful:
particle filter regeneration successful: regeneration completed correctly.
weight of soot too high - run command SC017 again: regeneration failed because the weight of soot at
the end of regeneration was too high and the temperature upstream of the particle filter was too low. Check
the oil level before starting another regeneration.
weight of soot too high: regeneration failed because the weight of soot at the end of regeneration was
too high in spite of the correct temperature upstream of the particle filter. The particle filter is full of residue
(regeneration impossible), refer to the fault finding chart ALP21 Particle filter warning light lit.
present or stored fault: regeneration failed because faults were declared.
Refer to the interpretation of faults, after resolving the faults, run command SC017 again.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool

NOTESOnly address this customer complaint after a complete check with the diagnostic
tool.
Check the grade of the engine oil and that the engine oil level is correct.
Perform fault finding on the charging circuit (see Technical Note 6014A, Checking the charging circuit).
Check the starter (see Technical Note 3632A, Starter fault finding).
Check the coolant temperature sensor, fuel sensor and air inlet sensor (refer to the interpretation of faults DF001
Coolant temperature sensor circuit, DF098 Fuel temperature sensor circuit and DF301 Air inlet circuit).
If the wiring is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Check the preheating system (refer to the interpretation of fault DF025 Preheating unit diagnostic line).
Check the low pressure fuel supply system by performing test 1 Low pressure supply check and test 2
Internal fuel transfer pump (ITP) check.
Check compression values.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

NOTESOnly address this customer complaint after a complete check with the diagnostic
tool.
Is the vehicle equipped with a particle filter?
(Vdiag 45, 49 and 4D only)
NO
Check the engine oil grade and level.
Check the presence and conformity of the fuel, by running Test 13 Diesel fuel conformity check, and its circuit
(see MR 385, 392, 364, 370 or 417, Mechanical, 13A, Fuel supply).
Check the cooling system (see MR 385 392 364, 370 or 417 Mechanics, 19A, Cooling, Engine cooling system:
Specifications).
Check the fuel temperature sensor (refer to the interpretation of Fuel temperature sensor circuit faults DF098).
Check the coolant temperature sensor (refer to the interpretation of faults DF001 Coolant temperature sensor
circuit).
Check the air inlet circuit (refer to the interpretation of fault DF301 Air inlet circuit).
Check that the damper valve operates correctly (refer to the interpretation of fault DF641 Damper valve circuit).
Check the air flowmeter (refer to the interpretation of faults DF039 Inlet air temperature sensor circuit, DF129 Air
flow requested and DF056 Air flow sensor circuit).
Check the turbocharging pressure (consult the interpretation of fault DF004 Turbocharging pressure sensor circuit).
Check the preheating system (refer to the interpretation of fault DF025 Preheating unit diagnostic line).
Check the injection computer: that the connections and wiring are in good condition, that earths and feeds are present.
If the wiring is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring:
Precautions for repair), repair the wiring, otherwise replace it.
YES
Deal with the following faults first: DF238
Thermoplunger no. 3 relay circuit, DF239
Thermoplunger no. 2 relay circuit, DF240
Thermoplunger no. 1 relay circuit and DF1005
Thermoplunger control unit fault finding 1
connection. Check the particle filter injector supply
circuit, by running Test 8 Checking the particle filter
injector supply circuit.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
