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.

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.
PA R T C
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.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

Procedure to switch off the Particle filter message or warning light on the instrument panel.
Certain types of driving can trigger the illumination of the particle filter warning light or message, and therefore
cause fault DF312 to appear. The customer must drive in a specific way (refer to vehicle's user manual) which
entails:
1. When the engine is warm, drive at a speed greater than 48 mph (80 km/h) for 2 minutes to trigger the
regeneration procedure.
2. Continue to drive at an average speed of 48 mph (80 km/h) until the "particle filter" message or warning light
on the instrument panel goes out. In order for the procedure to succeed, it is necessary to drive without
stopping the engine or leaving the engine running at idle speed for an extended period of time. The
regeneration time depends on the vehicle and driving conditions but should last for 20 minutes maximum.
If regeneration when driving fails (the warning light has not switched off or the service warning light has come on),
carry out a particle filter regeneration in the Renault dealership. First, check the exhaust pipe for leaks or
blockage. Repair if necessary.
Run command SC017 Particle filter regeneration (see Interpretation of commands).
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
