SPECIAL FEATURES: FORCED REGENERATION OF THE PARTICLE FILTER
Tools.
Diagnostic stations: LEXIA or PROXIA
Imperative: Respect the safety and cleanliness requirements.
Forced regeneration of the particle filter.
IMPERATIVE: Respect the safety and cleanliness requirements specific to HDi engines.
ESSENTIAL: Connect the vehicle to a gas extractor approved for this type of operation.In the absence of the required installations,carry out the forced regeneration of the particle filter outside the workshop, in a concreted
area well away from any inflammable materials. Place the vehicle in the high position.
WARNING:
Check that the fuel level is sufficient (at least 20 litres).
Start the engine and allow it to warm up (60°C minimum).
Connect the diagnostic tool to the vehicle’s central socket.
Trigger the regeneration cycle, with the diagnostic tool.
Automatic running of the regeneration cycle of the particle filter:
Autocheck by the engine ECU. Stabilisation of engine speed at
4000 rpm, operating with post injection.
Change to idling speed (for 30 seconds).
Stabilisation of engine speed at 3000 rpm, checking of the efficiency of the regeneration of the particle filter.
Change to idling speed.
NOTE:Let the engine run at idling speed for the benefit of cooling.
Stop the engine.
IMPERATIVE: Wait for at least an hour before any operation on the exhaust line.

SPECIAL FEATURES: PARTICLE FILTER / CHECKING THE ADDITIVE PUMP
Sealing of the additive injector.
Couple tool [1] to the tube (1).
Action the manual pump [1].
WARNING:The additive injector should open at a pressure of 100 ± 20 Bars.
Action the manual pump in vacuum
[1]at 800 m.bars.
WARNING:The downstream pressure should not fall rapidly.
NOTE:Replace the fuel tank if the injector is defective.
Couple the tube
(1).
Operate the actuator test «Filling the tube: additive pump – additive injector», with the aid ofLEXIAor PROXIA.
Check the additive level.
The checking of the additive level is done with reference to the gradations «a»marked on the additive
reservoir.
The top graduation indicates maximum filling
(3 Litres).
The difference between the two gradations equates to 0,25 Litres.
