PARAMETER
DEFINITIONThese parameters are shown in Km.
NOTESSpecial notes:
Interpret these parameters only if DF312 Speed request is present or stored.
Conformity check with the engine stopped and the ignition on, or with the engine running and the engine
coolant temperature > 80°C
These parameters are used so that the history of the last ten regeneration failures when driving are known.
For VDIAG 58, 18, 1C
Each of these parameters contains the vehicle mileage during a failed particle filter regeneration when driving.
Each parameter relates to an engine status. The statuses and parameters are recorded at the same time
(for example PR797 is associated with ET709 Engine status record no. 4).
Each new recorded value is saved under the next PR (PR+1).
When all ten parameters have a value other than zero and there is a regeneration failure when driving, the
mileage information for PR794 is cleared and replaced with the new value.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

For VDIAG 5C and 20
Each parameter between PR794 and PR803 contains the vehicle mileage when particle filter regeneration fails
when driving. Each parameter relates to an engine status. They are recorded simultaneously (for example, PR797
is associated with ET709 Engine status record no. 4).
PR795 to PR803 operate through successive feedback (when regeneration fails whilst driving, the value of
PR794 is copied in PR795, the value of PR795 is copied in PR796 and so on).
When there are more than ten records, the value of PR803 is overwritten. The new mileage is allocated to PR794.
If none of parameters PR794 to PR803 is available in the sub-function, this means that no record has been made.
The parameters appear in the sub-function when they have a value above zero.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

PARAMETER
DEFINITIONThese parameters are shown in Km.
NOTESSpecial notes:
Interpret these parameters only for ALP9 Particle filter warning light comes on too
often.
Conformity check with the engine stopped and the ignition on, or with the engine running and the engine
coolant temperature > 80°C
These parameters are used so that the history of the last ten activations of the particle filter warning light are
known.
For VDIAG 58, 18 and 1C
Each parameter between PR816 and PR825 contains the vehicle mileage when particle filter regeneration starts
when driving. Each parameter is connected with a "Rege* request status record". They are recorded
simultaneously (for example, PR819 is associated with ET745 Rege* request status record no. 4).
Each new recorded value is saved under the next PR (PR+1).
When all ten parameters have a value other than zero, and a new regeneration starts when driving, the mileage
information for PR816 is cleared and replaced with the new value.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

For VDIAG 5C and 20
Each parameter from PR816 to PR825 records the mileage when particle filter regeneration starts and the status
of each request is recorded by ET742 Rege* request status record no. 1 to ET751 Rege* request status
record no. 10 (for example, PR819 is associated with ET745 Rege* request status record no.4).
Each time a new regeneration when driving is started, the vehicle mileage is recorded in PR816, as well as its
status in ET742 Rege* request status record no. 1
PR816 to PR825 operate through successive feedback (when regeneration starts, the value of PR816 is copied to
PR817, the value of PR817 is copied to PR818 and so on).
When there are more than ten records, the value of PR825 is overwritten.
The new mileage is allocated to PR816.
If only parameter PR816 is available in the sub-function and it has a value of zero, this means that no record was
made.
If a recording has been made, it will have a value above zero.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.
