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.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

With + after ignition feed on, check for + 12 V feed between connection codes 3AHB and M at the electric pump
connector of the particle filter injector, component code 1767.
If there is no + 12 V feed to the sensor, check the continuity, insulation and absence of interference
resistance on the following connections:
●connection code 3AHB between components 1767 and 1768,
●Connection code M between component 1767 and the vehicle earth.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A,
Electrical wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
(Refer to the interpretation of faults DF1004 Electric fuel pump relay control and DF1001 Particle filter
upstream temperature regulation).
●Reconnect or replace the pipe.
Repeat the pressure test.
●Replace the fuel filter (see MR 392, 385, 364, 370 and 417 Mechanics, 13A, Fuel supply, Fuel filter:
Removal - Refitting).
Repeat the pressure test.
●Replace the particle filter injector electric pump.
Repeat the pressure test.
●Check that the particle filter injector is fitted correctly.
Check that the particle filter injector is correctly held in place. Repair or replace the particle filter injector mounting.
●"Only on Kangoo 2:
Check the integrity and correct fitting of the evaporator plate located under the particle filter injector, at the level of
the bracket.
If the blade of the evaporator plate has become detached, it may be located downstream from the line between its
original position and the oxidation catalytic converter inlet.

WARNING
During this operation, it is essential to:
– refrain from smoking or bringing incandescent objects close to the work area,
– protect yourself against fuel splashes due to residual pressure in the pipes,
– wear safety goggles with side guards,
– wear leaktight gloves (Nitrile type).
IMPORTANT
– To avoid any corrosion or damage, protect the areas on which fuel is likely to run.
– To prevent impurities from entering the circuit, place protective plugs on all fuel circuit components
exposed to the open air.
Preparations:
Weigh an empty 1300 ml plastic cup (part no. 77 11 171 413) with its cover (part no. 77 11 171 416) using
electronic scales such as those used in body paint workshops (example: PANDA part no. 77 11 224 995). Record
the weight of the empty plastic cup.
This type of plastic cup is used to prepare paint.
Take a 1 l fuel sample from the diesel fuel filter outlet (see MR 392 (Clio III), 364 (Mégane II ph2), and 417
(Kangoo II), Mechanical, 19C, Tank, Fuel tank: Draining, or MR 385 (Modus) and 370 (Scénic II ph2)
Mechanical, 19C, Tank, Draining the fuel tank), using a pneumatic transfer pump (part no. 634-200) and place
it in the 1300 ml plastic cup.
Cover the plastic cup with its cover and let the fuel settle for approximately 2 minutes.
Is the fuel cloudy or does it separate
into two parts?Presence of water in diesel fuel, the fuel is not compliant.
Drain the fuel circuit, including the tank (see MR 392 (Clio III),
