| IMPORTANT
Consult the safety and cleanliness advice and operation
recommendations before carrying out any
repair. |
IMPORTANT
Use the diagnostic tool before any operation is carried
out on the injection circuit to check:
- that the rail is not under pressure,
- that the fuel temperature is not too high.
Working on the circuit with the engine running is
strictly forbidden. |
IMPORTANT
During this operation, be sure to:
- refrain from smoking or bringing red hot objects
close to the working area,
- be careful of fuel splashes when disconnecting the
union.
|
| WARNING
To avoid any corrosion or damage, protect the
areas on which fuel is likely to run. |
| WARNING
Once the warranty period for the high pressure
pump has expired, only the pressure regulator can
be replaced separately.
Whilst the warranty period for the high pressure
pump is still running, the high pressure pump
should be replaced as a whole if the pressure regulator
displays a fault. |
REMOVAL
I - REMOVAL PREPARATION OPERATION
- Remove:
- the engine cover,
- the battery.
- Rotate the clip (1) of the intercooler air inlet pipe on
the turbocharger.
- Remove the intercooler air inlet pipe bolt (2) from the
fuel pipe support.
- Move aside the intercooler air inlet pipe.
- Remove:
- the protector plate (3) from the injector rail protector,
- the injector rail protector bolt (4) .
- Remove the wiring nut (5) .
- Remove the wiring bolt (6) .
- Move aside the wiring.
II - OPERATION FOR REMOVAL OF PART
CONCERNED
- Disconnect the rail pressure sensor connector.
- Remove the rail pressure sensor (7) .
- Insert the blanking plugs.
REFITTING
I - REFITTING PREPARATION OPERATION
- Always replace the seal of the intercooler air inlet
pipe.
| WARNING
Do not remove the blanking plugs from each
component until the last moment.
Also, do not remove the components from their
packaging until they are to be fitted to the vehicle. |
II - REFITTING OPERATION FOR PART
CONCERNED
- Remove the blanking plugs.
| Note:
The rail pressure sensor has no seal. |
| Note:
Use a torque wrench with an adapter for an
open-ended spanner (27 mm) to tighten the rail
pressure sensor. |
- Refit the rail pressure sensor.
- Torque tighten the rail pressure sensor (80 N.m).
- Connect the rail pressure sensor connector.
III - FINAL OPERATION.
- Fit the wiring.
- Refit:
- the wiring bolt,
- the wiring nut,
- the injector rail protector bolt.
- Torque tighten the injector rail protector bolt (8
N.m).
- Remove the intercooler air inlet pipe seal using a
tweezers.
| Note:
Check that the seal (8) on the intercooler air inlet
pipe is fitted the correct way round. |
- Refit:
- the new seal of the intercooler air inlet pipe,
- the protector plate on the injector rail protector.
- Turn the intercooler air inlet pipe to refit the clip in its
housing.
- Clip the intercooler air inlet pipe onto the turbocharger.
- Refit the intercooler air inlet pipe bolt on the fuel pipe
support.
- Torque tighten the intercooler air inlet pipe bolt (8
N.m).
- Connect the battery.
- Prime the fuel circuit using the manual priming pump.
- Refit the engine cover.
