The potentiometer serves to control and run fault finding on the valve. The very first time the engine is started, then
each subsequent engine start, the "valve closed" position is programmed (offset). This value is compared to the very
first offset or last programmed offset, for the purposes of fault finding. It is also used to readjust the valve control
function. It is therefore important to associate the EGR valve with the computer that controls it.
Important: the EGR valve offsets must be reinitialised when replacing the valve or reprogramming/replacing
the computer.
V - Catalysed particle filter management (only for Vdiag: 18, 1C, 54, 20, 58, 5C, 24, 28 and 62).
The particle filter prevents the escape of carbon particles emitted by the engine but not yet removed from the
exhaust gases.
The particle filter is a microporous structure containing channels in order to force filter the exhaust gas.
The exhaust pipe consists of several components:
– an oxidation catalytic converter mounted after the turbocharger. This catalytic converter ensures that HC/CO levels
meet current standards by generating the heat (rise in exhaust temperature caused by catalysis) required for
particle filter regeneration,
– a catalysed particle filter located under the bodywork,
– a differential pressure sensor to tell the computer the pressure upstream and downstream of the particle filter,
– a particle filter upstream and downstream temperature sensor,
– a turbine upstream temperature sensor (TAVT).
As the vehicle is driven, the particle filter is loaded with particles (soot). Using a given weight of soot determined via
mapping in the computer, regeneration mode can be triggered if the maximum weight of soot in the particle filter is
reached and all engine operating conditions are met (coolant temperature, etc.).
Particle filter regeneration consists of burning the particles of soot accumulated in the filter.
The differential pressure sensor measures the particle filter inlet/outlet pressure differential; this measurement is
used to estimate the weight of soot present in the particle filter by mapping in the computer:
(weight of soot = pressure differential as a function of exhaust volume flow rate).
If all the criteria are met, the computer enters regeneration mode. The injection programming is then adjusted in
order to raise the target exhaust gas temperature to between 550 and 650°C.
This temperature allows the particles accumulated in the filter to be partially or completely burnt (regeneration).
Regeneration efficiency depends on the particle filter inlet temperature and the time spent in regeneration mode.
Regeneration can be performed automatically while driving if:
–the soot weight is less than the threshold for DF308 Clogged particle filter
–the number of regeneration failures while driving is less than the threshold for DF311 Failed regenerations
limit exceeded.

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).

PART B
1. No particle filter regeneration.
2.Write on the repair order the parameter and status relating to the last failure:
– Mileage of the last DF312 Speed request.
– 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 repair order by the service advisor for the customer:
Before the last time the particle filter warning light or 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. Explain to the customer the procedure to turn off the warning light, making use of the parameters noted in the
repair order: see PART D.
PART C
If Vdiag 18:
Reprogram the computer in Vdiag 1C.
Then apply the procedure corresponding to Vdiag 1C.
If Vdiag 1C, 54, 58, 20 and 24:
– Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary.
– Carry out an After-Sales regeneration with approval from 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.
