Bleed the low and high pressure diesel circuit.
Does the starter motor work properly?
Ensure that the engine speed reaches PR055
Engine speed > ~ 200 rpm with the starter in
operation, Consult Technical Note 6014A, Checking the

ALP4 Poor performance
NOTESBefore analysing this customer complaint, check that there are no faults, and the
conformity (or otherwise) of the parameters and statuses, using the diagnostic
tool.
If the customer complaint is not eliminated, perform the following checks.
IMPORTANT
In the case of engine overheating to above 118°C, the computer deliberately limits the fuel flow (overheating
warning light lights up from 115°C).
Please observe the cleanliness guidelines and safety advice.
Is the poor performance accompanied by smoke?
Check the conformity of the fuel used by running test 11 Diesel fuel conformity check.
If the diesel fuel is not correct:
– Replace the diesel fuel.
– Change the diesel filter.
– Bleed the low and high pressure diesel circuit.
Test the high pressure fuel circuit:
Run the scenario SC035 High pressure fuel circuit fault finding (see Interpretation of commands).
Check that the injectors are correctly fitted (presence and conformity of the sealing washer).
Checking procedure:
– Take a straightedge approximately 40 cm long and place it on the 4 injectors. The straightedge should rest on
the 4 injectors.
– If 1 injector protrudes, remove the injector and check that the washer is correct.
– If one injector does not touch the straightedge (clearance of more than 1 mm), remove the injector and check
that the washer is present.
– Clean the injector wells and the injector, refit the injector with the correct sealing washer.
– The tightness seal and the condition of the inlet circuit: run test 4: Turbocharged air inlet circuit check.
– The condition of the air flowmeter, run test 5 Air flowmeter.
– The turbocharger, run the following tests:
– test 2: Air path at the turbocharger,
– test 6: Turbocharger control solenoid valve check,
– test 7: Turbocharger.

ALP11 Particle filter warning light comes on too often
NOTESThis ALP is specific to Vdiag48.
Before dealing with this customer complaint, check that there are no faults
except DF312 Speed request, and check the conformity (or otherwise) of the
"parameters" and "statuses" using the diagnostic tool. Deal with the other faults
first.
If the customer complaint is not eliminated, perform the following checks.
Have the last 10 regeneration attempts failed?
Is the mileage of PR412 Mileage of last successful
regeneration less than all the parameters of group 2? (PR794
to PR803 Stored regeneration failure no. 1 to no. 10)Is at least one status in group 1
= STATUS4?
Symptom not
confirmed
Are all the regeneration failures linked to engine cut-off?
See parameter ET706 Stored engine status no.1 to ET715
Stored engine status no.10 (E.g. ET706 STOPPED)
Check the exhaust pipe for leaks or blockage. Repair if
necessary.
Perform After-Sales regeneration if it was not performed
previously (see Interpretation of commands, SC017 Particle
filter regeneration)

Check:
– the condition of the damper valve,
– the tightening of the mounting bolts,
– cracks in the damper valve.
Carry out the necessary repairs.
Replace if necessary.
Check that there is no leak at the exhaust manifold, in particular at the exhaust manifold/turbocharger connection.
Check the exhaust system: run test 1 Exhaust pipe check in ALP2.
Carry out the necessary repairs.
Carry out a visual inspection of the EGR circuit sealing.
Note: the operating play in the EGR heat exchanger valve shaft produces small black marks due to a slight leak
of no importance. Do not replace this part.
Replace if necessary.
Check the condition of the intercooler:
– clogging,
– leaks (vehicle stationary, stabilise the engine speed between 3500 rpm and 4000 rpm and check that there are
no leaks).
Replace if necessary.
Check that the take-off point for the turbocharging pressure sensor is not blocked.
Replace if necessary.
