Only for F9Q816:
If the vehicle is not new (mileage greater than 10 km):
Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary
– Do an after-sales regeneration using the control SC017 Particle filter regeneration.
– Perform an oil change (see MR 364 (Mégane II) or MR 370 (Scénic II), Mechanical, 10A Engine and
peripherals, Engine oil: Draining – Filling).
If the fault is still present, contact the Techline.
13B-171
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.

Repair request with DF312 present or stored ONLY
Read the information from the sub-function Particle filter histo*: PR784 to PR793 DF312 No. 1 to No. 10 records
Are PR784 to PR793 all equal to 0 miles (0 km)?
Among these parameters (PR784 to PR793):
– Find the parameter with the highest mileage: it 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 in the Particle filter histo* sub-function:
PR794 to PR803 Stored regeneration failures No. 1 to No. 10.
Does at least one of parameters PR794 to PR803 = 19659 miles
(32766 Km)?
Identify the distance(s) from the values of parameters PR794 to PR803 Stored regeneration failures 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)

PART B
1. No particle filter regeneration.
2. Write on the repair order the parameter and status relating to the last failure:
Mileage of last DF312
Mileage of last failures
Engine statuses of 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 repair order by the service advisor for the customer:
Before the last time the Particle Filter message or warning light illuminated (appeared at the Mileage of the
last DF312), the customer had not adhered to the driving recommendations: the failure that occurred at the
Mileage of the last failure is due to the engine being switched off.
4. Explain to the customer the procedure to turn off the warning light, making use of the parameters noted in the
repair order: see PA R T D.
PART C
Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary
Carry out an After-Sales regeneration with the consent of the Techline.
Follow the procedure for command SC017 Particle filter regeneration (see Interpretation of commands).
Explain to the customer the procedure for regeneration when driving to avoid unnecessary repairs: see PART D.

This status indicates the engine status in the event of a regeneration failure when driving:
NONE, + AFTER IGNITION, RUNNING, STOPPED.
Each STATUS between ET706 and ET715 corresponds to the engine status during a regeneration failure for which
the mileage is saved by PR794 Stored regeneration failure No. 1 to PR803 Stored regeneration failure No. 10
(for example, PR797 Stored regeneration failure No. 4 is related to ET709 Stored engine status No. 4).

are connected to parameters PR816 Stored regeneration start No. 1 to PR825
Stored regeneration start No. 10 which contains the stored mileage of the vehicle at
the start of the regeneration (for example, PR745 Store regeneration start No. 4 is
related to ET709 Store regen.* request status No. 4).

reached and measured in the particle filter, without the particle filter warning light
coming on.
