Particle filter injector fuel system pressurisation check (pressure test):
To check the pressure in the particle filter injector fuel system:
●Connect the T-union Mot 1311-08 to the particle filter injector fuel filter outlet (adapter visible without
dismantling).
●Connect the pressure gauge Mot 1311-01 to the T-union.
Pressurise the fuel system using the diagnostic tool, and run command AC237 Fuel pump relay.
If the pressure in the system is about 1 bar, perform the command a second time.
The pressure must be at least 3 bar.
If the fuel pressure is less than 3 bar, proceed as follows:
●Carry out a visual inspection of the flexible supply hose to the particle filter injector, before and after the
T-union (leaks, pinching, fuel filter condition, etc.).
Pressurise the fuel system again with the diagnostic tool, and run command AC237 Fuel pump relay.
If the pressure is not equal to or above 3 bar, replace the pump/sender unit (see Technical Note 5117A, Special
features of vehicles fitted with the K9K 772 engine).
Checking the pressure regulator:
●Run command AC237 Fuel pump relay, until the fuel pressure reaches 5 bar.
●Reactivate command AC237 Fuel pump relay again to check that the pressure is controlled between 5.5 bar
and 5 bar.
If the regulator is not working, replace the pump/sender unit (see Technical Note 5117A, Special features of
vehicles fitted with the K9K 772 engine).
Note:
To reduce the pressure in the system, run command AC238 Particle filter injector, until it drops to 3 bar, then
carefully disconnect the union.

1 - NO particle filter regeneration.
2 - Write on the repair order: the parameter and status relating to the last failure:
– Mileage of last Particle filter warning light record
– Mileage of last Failed regeneration records
– Engine statuses for last Engine status records
Example: PR837 = 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 warning light or Particle Filter message came on (appeared at the mileage of the last
Stored particle filter warning light) the customer did not follow the driving instructions: the failure which
occurred at the Mileage of the last failure was due to the engine being switched off.
4 - Service advisor explains to the customer the procedure to turn off the warning light, backed up by the
parameters written in the repair order: see PA R T D.
PA R T C
1 - Carry out a regeneration in the Renault dealership with the approval of the Techline.
Follow the procedure for command SC017 Particle filter regeneration.
Note: Do not carry out an engine oil change following an After-Sales regeneration.
2 - Explain the procedure for regeneration while driving to the customer to reduce returns to the garage:
see SECTION D:

SECTION D - Procedure for switching off the particle filter message or warning light on the instrument panel
Certain types of driving can trigger the activation of the particle filter warning light or message. This fault occurs
when the weight of soot is more than 30.8 g.
The customer must carry out a specific driving operation (cf. vehicle user manual) that consists of:
1. Making sure the engine is warm
2. Drive at a speed greater than 24 mph (40 km/h) for 2 minutes to initiate the regeneration process.
Initiating regeneration Minimum speed Minimum time
All vehicle types 24 mph (40 km/h) 2 minutes
3. Then drive at a speed of more than 24 mph (40 km/h) until the Particle Filter message or warning light on the
instrument panel goes out. In order for the procedure to succeed, it is necessary to drive without stopping
(without stopping the engine) or to leave the engine running at idle speed for an extended period of time. The
regeneration time depends on the vehicle and driving conditions but normally lasts about 20 minutes.
Regeneration duration Minimum speed Average time
All vehicle types 24 mph (40 km/h) 20 minutes
4. If regeneration when driving fails (the warning light has not switched off or the service warning light has come
on), carry out a particle filter regeneration in the Renault dealership. To carry out After-Sales regeneration:
check the oil level and remove some oil if the maximum level has been reached, then apply the procedure for
command SC017 Particle filter regeneration (see Interpretation of commands).
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

High pressure circuit check
Note:
According to the vehicle type, maximum visual
access will either be from above or from below.
Visually inspect the condition of the following
components:
– outlet pipe of the compressor to the
turbocharging air cooler,
– turbocharging air cooler outlet pipe at inlet
manifold,
– inlet manifold,
– temperature and pressure sensors.
Is one of these components incorrect
(disconnected, cut, bent, pierced or kinked
pipes)?
NO
Exhaust system check
Visually inspect the condition of the following
engine parts:
– the exhaust manifold circuit to the
turbocharger turbine,
– the turbine outlet pipe to the end of the
exhaust pipe,
– from the inlet manifold to the EGR valve,
– check that the temperature and pressure
sensors are connected.
Do some of these components have blackish
or whitish traces?
NO
