NOTESOnly address this customer complaint after a complete check with the diagnostic
tool.
If the noise is coming from the turbocharger, apply the Technical Note 5164A, Fault finding of noises.
Note:
Pay close attention to faulty components that might result in unjustified replacement of the turbocharger. For
example, whistling does not necessarily indicate damage to the turbocharger (this could be coming from the
exhaust, the timing, the gearbox, etc.).

TEST 7 High pressure circuit sealing check
NOTESSpecial note:
Certain faults make it impossible to carry out this test - deal with these first.
The command AC029 High pressure circuit sealing test enables a high pressure circuit sealing test to be
carried out when the engine is running.
This command can locate a leak in the high pressure circuit if a union is incorrectly fitted or screwed on. This test
does not identify a minor leak due to a union not being tightened to torque.
This command can be used only if the engine temperature is greater than 60ºC.
Watch out for any objects (tool or others) on the sides of the engine housing during the 4 accelerations
(possible vibrations).
Run command AC029 High pressure circuit sealing test, the engine will automatically carry out a cycle of
four accelerations to increase the rail pressure and check for leaks in the high pressure circuit.

TEST 8 Injector return flow
NOTESSpecial note:
Certain faults make it impossible to carry out this test - deal with these first.
Does the engine start?
Command AC029 High pressure circuit sealing also checks the return volume of each injector to detect any
leaks around the injectors.
Be careful with any objects (tool or other) on the engine housing during the four cycles of the operation
(possible vibrations).
Tooling required
–Mot. 1711 Injector flow measuring kit.
Or: Use four pipes with internal diameter 4mm and approximately 50 cm in length, and four graduated
measuring cylinders.
Procedure
– Ensure that the engine coolant temperature is above 60°C,
– switch off the ignition,
– disconnect the return pipes from the four injectors,
– cap the pump venturi tube to prevent the low-pressure circuit from depriming,
– connect the four transparent tubes in place of the return pipes,
– put the other ends of the four pipes into four graduated measuring cylinders.
