– Switch off the ignition, reconnect the electrical
connections to the four injectors and the low-pressure
actuator.
– Switch on the ignition again, and clear the injection
faults using the diagnostic tool.
– Check if there is no fuel leak in the high pressure
circuit. Run TEST 7 High pressure circuit sealing
check
– Check the conformity of the diesel filter. Run TEST 9
Diesel fuel filter check.
– Carry out fault finding on the injectors by checking the
return flow volume of the four injectors, run TEST 8
Injector return flow.
Is TEST 8 OK?The pump can supply the operating pressure.
Switch off the ignition, reconnect the electrical
connections
to the four injectors and the low pressure
actuator. Switch on the ignition again, and clear
the injection faults using the diagnostic tool.
– Check that there is no fuel leak in the high
pressure circuit, apply TEST 7 High pressure
circuit sealing check.
– Carry out fault finding on the injectors by
checking the return flow volume of the four
injectors, run TEST 8 Injector return flow.
If TEST 8 is correct, the high pressure fuel circuit
is correct.
Replace the faulty injector(s) (see MR
388 (Logan/Sandero), MR 451
(Duster), MR 423 (Thalia 2/Symbol 2)
or MR 374 (Kangoo VLL), Mechanical,

TEST 9 Diesel filter check
Check the conformity of the diesel filter.
Is the diesel filter in order?Replace the filter with an original
part (see MR 388 (Logan/Sandero),
MR 451 (Duster), MR 423 (Thalia 2/
Symbol 2) or MR 374 (Kangoo VLL),
Mechanical, 13A, Fuel supply, Fuel
filter: Removal - Refitting).
Switch off the ignition and analyse the diesel fuel in the diesel filter.
– Disconnect the diesel supply and return hoses from the filter.
– Block the filter inlets and outlets straight away with appropriate plugs.
– Remove the filter from its support and shake it well keeping the plugs in place and empty the contents of the
filter into a glass container by lifting up a protective plug and undoing the bleed screw.
Check whether there are black particles present at the bottom of the container.
Pass a magnet beneath the container to collect all the
metal particles.
Take the magnet away from the container.Diesel filter in good order.
Do the particles collected using the magnet cover a surface
area greater than 1 cm
2?
Replace the entire injection
system.Diesel filter in good
order.

TEST 11 Turbocharger air chain
Check for the air filter
Check the replacement interval of the air filter on the maintenance booklet.
Compare the part numbers of the air filter fitted to the vehicle and that of the air filter recommended by the
manufacturer.
Check the air filter direction of fitting.
Is the air filter fitted to the vehicle correct?
Check the condition of the air filter
Visually inspect the condition of the filtering section of the
air filter.
Is either the air filter or its seal damaged?
Is the air filter fouled (does it contain a lot of
impurities)?Replace the air filter (see MR 388
(Logan/Sandero), MR 423
(Thalia 2/Symbol 2), MR 451
(Duster) or MR 374 (Kangoo
VLL), Mechanical, 12A, Fuel
mixture, Air filter: Removal -
Refitting).
Low pressure circuit check
Note:
Depending on the vehicle type, the best visual access will
be either from above or from below.
Visually inspect the condition of the following
components:
– fresh air inlet scoop on the front panel of the vehicle,
– air inlet pipe to the air filter,
– air pipe of the filter until the compressor inlet,
– mountings of the air flowmeter.
Is one of these components incorrect (disconnected,
cut, bent, pierced or kinked pipes)?Replace the faulty parts (see MR
388 (Logan/Sandero), MR 451
(Duster), MR 423 (Thalia 2/
Symbol 2) or MR 374 (Kangoo

WARNING
During this operation, it is essential to:
– refrain from smoking or bringing incandescent objects close to the work area,
– guard against petrol splashes caused by the 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.
Remove 1 l of fuel at the diesel filter outlet (see MR 388 (Logan/Sandero), MR 451 (Duster), MR 423 (Thalia
2/Symbol 2) or MR 374 (Kangoo VLL), 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 it 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 system, including the tank (see MR 388 (Logan/
Sandero), MR 451 (Duster), MR 423 (Thalia 2/Symbol 2) or MR 374
(Kangoo VLL), Mechanical, 19C, Tank, Draining the fuel tank).
