Removal
Disconnect the negative battery terminal.
Connect the pressure measuring hose to the bleed valve (1) of the fuel supply circuit.
Drain the fuel into a suitable container.
Release the wire harness (2) from the clamps.
Disconnect the connectors (3).
Disconnect the EGR valve pipe (4).
Unscrew bolts (5) and (6) and nuts TU.
Remove:
- hose kit (8);
- air supply pipe (9);
- vacuum supply tube;
- electrical connector located under the intake manifold;
- intake manifold (see the corresponding operation).
Clean the high pressure hoses before unscrewing them.
Cover the generator and starter.
Using "Sodimac" or similar, clean the zones "a "(see picture).
Caution: After opening the fuel injection circuit, no cleaning is permitted.
Disconnect the fuel supply pipe (11).
Unscrew the nuts (10) of the noise-insulating gasket.
Remove the tube (12) and soundproofing element (13) of the fuel distribution rail.
Close the fasteners on the pipes (11) of the fuel distribution rail (12) and the high-pressure fuel pump with plugs. Unscrew the fastening bolts (14) and remove the fuel distribution rail (remove manually by pulling several times).
Note: Move the injectors by turning them several times to break the layer of deposits that has formed between the injector and the combustion chamber.
If the fuel injection rail cannot be removed by hand, insert two flat-head screwdrivers into area "a" to lift it up.

Close the holes in the injectors with plugs.
Remove the clamps (15) and injectors (16) using a screwdriver.
Plug all open holes in the high pressure circuit.
Replacing the injector sealing washer
Remove the sealing washer (17), being careful not to scratch the injector (using snap ring pliers).
Clean the injector nozzles with a brush using Sodimac/Mecanet degreaser.
Caution: Do not clean the injectors with a rag or compressed air.
Install the new gasket into the injector groove, having first placed it onto the tool sleeve.
Insert the nozzle into the body of the device.
Note: Once the gasket is placed on the injector body, it must be installed in place as quickly as possible.
Installation
Note: Replace the gaskets (18) - (19), clamps (15) and high pressure pipe (20).
