NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after a road test.
Priorities when dealing with a number of faults:
– DF118 EGR solenoid valve servo-control,
– DF209 EGR valve position sensor circuit,
– DF272 EGR valve control circuit,
if they are present or stored.
Special note:
If the fault is present:
– the EGR function is inhibited,
– particle filter regeneration is inhibited,
– turbocharging is inhibited,
– the level 1 warning light is lit.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
IMPORTANT
This fault can result in a rapid and significant fouling of the particle filter. If the EGR
valve needs to be replaced to resolve the fault, use command SC036 Reinitialise
programming and select EGR valve to reinitialise the EGR valve offsets (see
Replacement of components).
Check the EGR valve connections.
Check the injection computer connections.
Repair if necessary.
Check the operation of the EGR valve:
– exit fault finding mode in CLIP,
– switch off the vehicle ignition,
– disconnect the EGR valve connector,
– remove the EGR valve.
– Check that there are no particles blocking the movement of the piston.
– Clean the EGR valve, (see Technical Note 3916A Cleaning the EGR valve).
– Refit the EGR valve, run command SC036 Reinitialise programming and select EGR valve to reinitialise the
EGR valve offsets (see Replacement of components).
If the valve is jammed or irrevocably seized, replace the EGR valve. Run command SC036 Reinitialise
programming and select EGR valve to reinitialise the EGR valve offsets (see Replacement of components).
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
– the level 1 warning light is lit,
– the OBD warning light illuminates after three consecutive driving cycles (starting

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault becomes present during an After-Sales regeneration carried out using the
diagnostic tool at a speed above zero.
Special notes:
If the fault is present, the particle filter regeneration in progress is interrupted.
IMPORTANT
The fault is present because the vehicle has been driven while the After-Sales regeneration was in
progress.
The vehicle must remain stationary throughout regeneration.
DO NOT DRIVE THE VEHICLE.
CHECK THAT THE VEHICLE IS CORRECTLY IMMOBILISED.
– switch off the ignition and wait for the diagnostic tool message:
“Loss of dialogue with the computer, check the tool connection and the computer supply”,
– switch on the ignition,
– establish dialogue with the injection computer,
– Check that there are no leaks or blockages in the exhaust pipe,
– Repair if necessary
– carry out another After-Sales regeneration,
– Run command SC017 Particle filter regeneration and follow the procedure (see Interpretation of
commands).
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

STATUS 9
Vehicle speed monitoring
Status ET415 changes to STATUS 9 if the vehicle speed received by the computer is
invalid or absent.
This signal is conveyed on the multiplex line and deactivates the cruise control.
Carry out a multiplex network test, then Perform fault finding on the ABS computer.
Deal with any present or stored faults (see 38C, Anti-lock braking system,
interpretation of faults).
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status 9 continues, contact the Techline.
STATUS 10Monitoring by injection computer
Status ET415 becomes "STATUS 10" when driving with cruise control active (ET042
"Cruise control/speed limiter": CRUISE CONTROL) if the injection computer detects
a fault anywhere in the engine management system, or an engine speed that is too high
or too low.
This signal is conveyed on the multiplex line and deactivates the cruise control.
Carry out a multiplex network test, then Perform fault finding on the injection computer.
Deal with present or stored faults.
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status 10 continues, contact the Techline.

Vehicle with ignition on, and the engine stopped for over 1 minute:
Compare the values of PR041 and PR035 Atmospheric pressure.
If the difference between PR041 and PR035 Atmospheric pressure is greater than 0.1 bar,
check the value of PR035 Atmospheric pressure by comparing it with the reading on a vehicle in the workshop
which is correct.
If the value of PR035 Atmospheric pressure is not correct (difference greater than 0.1 bar between
the 2 vehicles), contact the Techline.
Otherwise (when the value PR035 Atmospheric pressure is correct), change the turbocharging pressure
sensor.
If the difference between PR041 and PR035 Atmospheric pressure is less than 0.1 bar.
Start the engine, with the engine idling:
Compare the values of PR041 and PR035 Atmospheric pressure.
If the difference between PR041 and PR035 Atmospheric pressure is greater than 0.2 bar.
Check the air inlet circuit:
absence of leaks or blockages in the low and high pressure air circuit: ducts, presence and tightness of the
mounting clips, mounting of the turbocharger pressure sensor, intercooler, etc.
Check that the damper valve is not jammed closed.
Repair if necessary.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

– check that the damper valve is not jammed.
Carry out the necessary repairs.
Check the electrical conformity of the air flowmeter:
Check the + 5 V supply to the air flowmeter on connection 3KJ between components 120 and 799.
Check the + 12 V after relay supply to the air flowmeter on connection 3B between components 120 and 799.
Check the continuity and the absence of interference resistance on the following connections:
– connection code 3DV,
– connection code 3DW.
Between components 120 and 799.
If any of the connections are faulty and there is a repair method (see Technical Note 6015A, Electrical wiring
repair, Wiring: precautions for repairs), repair the wiring; otherwise replace the wiring.
With the flow meter connected, the vehicle ignition on and engine stopped:
Measure the voltage between connections 3DV and 3DW between components 120 and 799.
Replace the air flowmeter if its voltage is not approximately 0.5 V < PR073 Air flowmeter supply voltage < 0.7 V.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
