The fault appears if the weight of soot contained in the particle filter exceeds:
– 74 g for Scénic II and 66 g for Mégane II Vdiag 58 and 5C
– 45g for Vdiag 50.
–56 g for Vdiag 18.
– 59 g for Vdiag 1C and 20.
Step 1:
Run TEST 2 Air path at the turbocharger.
If the air path is not correct:
– Repair the leak,
– replace the particle filter,
– run command SC036 Reinitialise programming (see Interpretation of commands) and select After
particle filter replacement.
– Clear fault DF308, if Present or Stored.
IMPORTANT: DF308 must be cleared within the 3 minutes following the last power latch.
– 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.
If the air path is in order, go to Step 2.
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:
– 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.
