PRECAUTIONS
Cylinder NO.1 is at the flywheel end.
-1: Crankshaft pulley
ENGINE RUNNING
No work should be carried out on the hydraulic system while engine is running.
Remember that fuel pressure values in hydraulic circuit can reach up to 1,600 bar.
Keep hands or face (particularly eyes) out of any high pressure leak.
Recall that fuel is dangerous for health.
FUEL RAIL PRESSURE SENSOR
Under warranty, do not remove the fuel rail pressure sensor from the rail.
Do not try to measure the resistance of the fuel rail pressure sensor. This test is destructive for the
internal components.
FUEL INJECTOR
Fuel injectors are driven by over 100V.
FUEL injector electronics are polarised. In case of intervention on wiring harness, do not
invertwires. It is destructive for the piezo components.
Do not drive the fuel injectors if their body is not connected to the battery ground (risk ofelectro-
static discharge). For instance, fuel injector body have to be in contact with cylinder.
Piezo fuel injector connector must not be unplugged while engine is running. Risk of majordamage
to the engine (fuel injector could stay opened).
CleanlinessINFOID:0000000001162747
Cleanliness
RISKS ASSOCIATED WITH CONTAMINATION
The high pressure direct injection system is highly sensitive to contamination. The risks associated withcon-
tamination are:
 damage to or destruction of the high pressure injection system,
 components jamming,
 components losing seal integrity.
All After-Sales operations must be performed under very clean conditions. This means that no impurities (par-
ticles a few microns in size) should have entered the system during dismantling.
The cleanliness principle must be applied from the filter to the fuel injectors.
What are the sources of contamination?
 metal or plastic chips,
 paint,
fibres:
- from cardboard,
- from brushes,
- from paper,
- from clothing,
- from cloths,
 foreign bodies such as hair,
 ambient air
etc.
NOTE:
Cleaning the engine using a high pressure washer is prohibited because of the risk of damaging connections.
In addition, moisture may collect in the connectors and create electrical connection malfunction.

NOTE:
Before any work is carried out on the high pressure injection system, protect:
 the accessories and timing belts,
 the electrical accessories, (starter, alternator, electric power assisted steering pump),
 the flywheel surface, to prevent any diesel from running onto the clutch friction plate.
 Check that you have plugs for the unions to be opened (set of plugs available from the Parts Department).
The plugs are single-use only. After use, they must be discarded (once used they are soiled and cleaning is
not sufficient to make them reusable). Unused plugs must be discarded.
 Check that you have hermetically resealable plastic bags for storing removed parts. Stored parts will there-
fore be less subject to the risk of impurities. The bags are to be used once only, and discarded after use.
 Use lint-free cleaning cloths. Using normal cloth or paper is prohibited. They are not lint-free and could con-
taminate the fuel circuit. Each cloth should only be used once.
 Use fresh cleaning agent for each operation (used cleaning agent is contaminated). Pour it into an uncon-
taminated container.
 For each operation, use a clean brush in good condition (the brush must not shed its bristles).
 Use a brush and cleaning agent to clean the unions to be opened.
 Blast compressed air over the cleaned parts (tools, workbench, the parts, unions and injection system
zones). Check that no bristles remain.
 Wash your hands before and during the operation if necessary.
 When wearing leather protective gloves cover them with latex gloves to prevent contamination.
INSTRUCTIONS TO BE FOLLOWED WHEN CARRYING OUT ANY WORK
 As soon as the circuit is open, all openings must be plugged to prevent impurities from entering the system.
The plugs to be used are available from the Parts Department. The plugs must not be reused under any cir-
cumstances.
 Seal the pouch shut, even if it has to be opened shortly afterwards. Ambient air carries contamination.
 All components removed from the injection system must be stored in a hermetically sealed plastic bag once
they have been plugged.
 Using a brush, cleaning agent, air gun, sponge or normal cloth is strictly prohibited once the circuit has been
opened. These items could allow contamination to enter the system.
 A new component replacing an old one must not be removed from its packaging until it is to be fitted to the
vehicle.
