NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
– the level 1 warning light is lit,
– particle filter regenerations when driving are inhibited.
Use bornier Ele. 1681 for all operations on the engine management computer
connector.
Priorities when dealing with a number of faults:
Firstly, deal with the following faults:
– DF308 Particle filter clogged if it is present or stored,
– DF226 Damper valve circuit if it is present or stored,
– DF272 EGR valve control circuit if it is present or stored.
The fault appears after a certain number of failed regeneration attempts while driving (between 10 and 12
for MEGANE II and SCENIC II; between 6 and 8 for LAGUNA II).
–Run TEST 2 Air path at the turbocharger.
Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary
– Carry out an After-Sales regeneration.
– Follow the procedure for command SC017 Particle filter regeneration (see Interpretation of commands).
Carry out an oil change if the particle filter is replaced.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
– a warning message or a special particle filter warning light is displayed on the
instrument panel,
– A specific kind of driving is required to bring about regeneration of the
particle filter when driving.
Use bornier Ele. 1681 for all operations on the engine management computer
connector.
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 Number of failed regenerations exceeded if it is present or stored,
– DF226 Damper valve circuit if it is present or stored,
–DF272 EGR valve control circuit if it is present or stored.

– 8 failed regeneration attempts while driving for Vdiag 18
– 6 failed regeneration attempts while driving for Vdiag 1C and 20
–Run TEST 2 Air path at the turbocharger. Then continue fault finding by applying the following flow chart.

Repair request with DF312 present or stored ONLY
Read the information from the Particle filter history sub-function: PR784 to PR793 Stored DF312 no. 1 to no. 10
Are PR784 to PR793 all equal to 0 miles (0 km)?
NO YES
Among these parameters (PR784 to PR793):
– Find the parameter with the highest mileage: this is the mileage of the last DF312.
– Note the parameter index on the order of repair with the relevant mileage value.
E.g.: PR787 = 2794 miles (4657 Km)
Read the information from the Particle filter history sub-function:PR794 to PR803 Failed regeneration
records no. 1 to no. 10.
vdiag 5C and 20vdiag 50, 58, 18 and 1C
Is at least one of PR794 to PR803 = 19660 miles (32766 km)?YES
NO
Identify the distance(s) from the values of parameters PR794 to PR803 Failed regeneration records no. 1
to no. 10, included between the Mileage of the last DF312 and the Mileage of the last DF312 – 120 miles
(200 km). These are the mileages of the last failures.
Example: 2674 miles (4457 km) < PR801 = 2760 miles (4600 km) < 2794 miles (4657 km)
Is there at least one?
NO YES
Within ET706 to ET715 Stored engine status no. 1 to no. 10:
– Read the values of the statuses relating to the mileage of the last failures.
– These are the engine statuses of the last failures.
Is the engine status value for one of the last failures
STOPPED?NO
YES
– Read in the context of the appearance of fault DF312, PR383 Weight of soot in the particle filter.
It is the soot deposit at the time of DF312.
– Read in the current context, the current value of PR383 Weight of soot in the particle filter
NO Current value of PR383 > soot weight at the time of DF312 + 5g? YES
Contact the Techline.

1 NO particle filter regeneration.
2 On the repair order, note the parameter and the status that correspond to the last failure:
– Mileage of the last DF312.
– Mileage of the last failures.
– Engine statuses of the last failures.
E.g.: PR787 = 2794 miles (4657 km); PR801 = 2760 miles (4600 km); engine status = STOPPED.
3 Interpretation of the values written on the order of repair by the service advisor for the customer:
Before the last time the warning light or Particle Filter message came on (appeared at the Mileage of the last
DF312), the customer had not respected the driving recommendations: the failure that occurred at the Mileage of
the last failure is due to the engine being switched off.
4 Check the weight of soot: PR383 Weight of soot in the particle filter.
If PR383
≥ 1 g. Apply the procedure for test 8 Manual clearing of the soot weight.
5 Explain to the customer the procedure to turn off the warning light, backed up by the parameters written in the
repair order: see PART D.

1- Carry out a regeneration in the Renault network with the approval of the Techline.
2- Change the oil and replace the oil filter if requested by a message on the diagnostic tool.
3- Run command SC036 Reinitialise programming and select After particle filter replacement.
4- Explain to the customer the procedure for regeneration when driving in order to avoid unnecessary repairs: see
PART D.
