frequencyWhat to tell the
customer?
Output 1The last 10 regeneration
attempts have failed due to
the engine cutting out.Regeneration failures
caused by engine cut-off.No regeneration
frequency analysis.Explain to the customer
the need to wait until the
end of regeneration
(warning light goes out)
before switching off the
engine.
Output 2The last 10 regeneration
attempts have failed but
not because of the engine
cutting out.Unsuitable driving
conditions.No regeneration
frequency analysis.Explain again to the
customer the driving
criteria for when the
warning light comes on.
Output 3After successful
regenerations stored in the
memory, the warning light
did not come on. No
interval can be calculated.Since the last successful
stored regenerations, the
driving conditions have not
allowed the warning light to
come on.Should be normal Vehicle correct
Output 4The interval between a
successful regeneration
and the particle filter
warning light coming on is
correct (above the lowest
possible values). The
system does not have any
irregular components.Unfavourable driving
(urban zone, underspeed,
etc.)Normal Vehicle correct

TEST1 Exhaust system check
Engine stopped: Check that the silencer outlet is
not blocked. Repair or replace the silencer, if
necessary.
Check the seal of the exhaust manifold on the
contact surface between the turbocharger and the
exhaust manifold.
Is the seal in order?Repair or replace the faulty part.
Loosen the catalytic converter on the turbocharger
side.
Place a wooden block between the two parts.
Start the vehicle and check if the engine runs
better.
Is the engine running normally?The exhaust system is not the cause of the fault;
repeat the engine fault finding (see Customer
complaints - Fault finding chart).
Retighten the catalytic converter.
Loosen or separate the particle filter on the
catalytic converter side. Place a wooden block
between the two parts if necessary.
Start the vehicle and check if the engine runs
better.

TEST3 Low pressure circuit check
Check the fuel filter:
– Conformity of the fuel filter (correct part number and RENAULT filter).
– Positioning and degree of clogging of the filter cartridge.
– Positioning and condition of the seals.
– If there is metal swarf in the filter:
Replace the fuel filter, bleed the circuit and continue the fault finding procedure.
Supplying the injection system with fuel from an additional tank.
This operation aims to detect possible faults in the low pressure supply system of a vehicle by replacing it entirely
with an additional tank.
Mode:
– Disconnect the diesel fuel supply pipe at the fuel filter inlet and block it with a plug.
– Connect a pipe to the fuel filter inlet and insert the other end in a clean container with a capacity of approximately
5 litres.
– Disconnect the diesel fuel return pipe at the diesel temperature sensor (pump return and injector return join), and
block it using a plug.
– Connect a transparent pipe to the union of the diesel fuel temperature sensor, and insert the other end in the
container.
– Fill the container with clean diesel fuel.
– Start the engine and let the system drain itself of its air (there must not be any air bubbles in the return pipe).
Is the customer complaint still present?If the low pressure circuit is in order, reconnect the
various low pressure circuit pipes, and repeat the
fault finding chart procedure or the procedure for
the fault that referred you to this test.
Are the low pressure circuit connections in order
and in good condition?Carry out the necessary repairs.
