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.

SPEEDOMETERALL TYPES
An E.E.C. decree of 25 June 1976, regulates the speed displayed by the speedmeter in relation to the actual speed travelled.
This decree stipulates:
The speed indicated by a speedometer must never be lower than the actual vehicle speed.
Between the speed displayed «SD»and the speed travelled «ST», there must always be the following relationship:
ST < SD < 1.10 ST + 4 Kph
Example: For an actual speed of 100 Kphthe speed displayed by the speedometer may be between 100and 114 Kph.
The speed indicated by the speedometer may be influenced by:
The speedometer.
The tyres fitted to the vehicle.
The final drive ratio.
The speedometer drive ratio.
Any of these components can be checked without removing them from the vehicle
(see information note N° 78-85 TT of 19 October 1978).NOTE:Before replacing the speedometer, check the conformity of the following points:
The tyres fitted to the vehicle.
The gearbox final drive ratio.
The speedometer drive ratio.
