STATUS1Request by weight of soot
Regeneration was requested based on the measurement of maximum soot weight in
the particle filter, without the particle filter warning light coming on.
STATUS2Request by estimated weight of soot
Regeneration was requested based on an estimation of maximum soot weight in the
particle filter, without the particle filter warning light coming on.
STATUS3Request by distance travelled
Regeneration has been requested after a maximum distance has been travelled
since the last successful regeneration without the particle filter warning light
coming on.
STATUS4Request by number of regeneration failures or weight of soot
This status corresponds to the appearance of DF312 Speed request.
This corresponds to the maximum number of failed regeneration or to the maximum
weight of soot in the particle filter, with the particle filter warning light coming on.

These parameters are used so that the history of the last ten activations of the particle filter warning light are
known.
In Vdiag 18, 1C, 54:
Each parameter from PR784 to PR793 records the distance when the particle filter warning light comes on which
is associated with the appearance of DF312.
Each time the particle filter warning light comes on, the vehicle mileage is stored in the following parameter (PR+1).
When all ten parameters have a value other than zero, and the particle filter warning light comes on again, the
distance information for PR784 is cleared and replaced by the new value.
For other Vdiags:
Each parameter from PR784 DF312 record no. 1 to PR793 DF312 record no. 10 contains a record of the vehicle
mileage when the particle filter warning light comes on. The appearance of fault DF312 Speed request is
associated with each of these parameters.
PR784 to PR793 operate through successive copying (when the particle filter warning light comes on, the value of
PR784 is copied to PR785 DF312 record no. 2, the value of PR785 is copied to PR786 DF312 record no. 3 and
so on).
When there are more than ten records, the value of PR793 is deleted. The new mileage is allocated to PR784.
If none of the parameters between PR784 and PR793 is available in the sub-function, this means that no data has
been saved. The parameters appear in the sub-function when they have a value above zero.

Fault finding – Interpretation of commands13B
SC017PARTICLE FILTER REGENERATION
NOTESOnly run this command after interpretation of the following faults:
– DF308 Clogged particle filter,
– DF311 Failed regenerations limit exceeded,
– df312: speed request.
WARNING:
– It is essential to observe the health and safety guidelines (see MR364 (Mégane II ph2), MR370 (Scénic II ph2),
MR 395 (Laguna II ph2), 402 (Vel Satis ph2), 405 (Espace IV ph2) Mechanical, 19B, Exhaust, Particle
filter: Cleaning) and follow the procedure below.
SAFETY INSTRUCTIONS TO BE FOLLOWED:
The regeneration causes exhaust fumes and high temperatures.
It is strongly recommended that you put the vehicle outside during regeneration.
If it is not possible to carry out regeneration outside, use an extractor fan that can withstand the very high
regeneration temperatures (400°C at the exhaust outlet).
Perform regeneration on a surface free from fire risks (oil, dry leaves, etc.).
Nothing should be left in the vicinity of the exhaust pipe.
Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary.
WARNING:
Check the engine oil level before running the command to avoid any engine racing. The oil level must be
between the minimum level and the middle level on the oil dipstick.
Before performing a particle filter regeneration, it is essential to deactivate the air conditioning
compressor (risk of engine damage) and all the electrical consumers.
IF NECESSARY:
Regeneration can be stopped by pressing the engine start button twice briefly (less than 3 seconds).
Switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes) Communication
lost with computer: EDC16 C33, check the tool connection and the computer power supply before
switching the ignition back on.

NOTESBefore dealing with this customer complaint, check that there are no faults except
DF312 Speed request, and the conformity (or otherwise) of the "parameters" and
"statuses" using the diagnostic tool. Deal with the other faults first.
If the customer complaint is not eliminated, perform the following checks.
Have the last 10 regeneration
attempts failed?Are all the regeneration failures
linked to engine cut-off?
See group parameter (ET706
