Visual inspection of the solenoid valve electrical connector
Switch off the engine.
Note:
The requested checks are entirely visual.
1- Check that the connector is correctly connected and locked.
2- Check that the electric wires are not damaged where they leave the insulation.
Disconnect the connector to continue the checks.
3- Check that there is no heat damage to the unit and mechanical damage to the lock.
4- Check that the contacts (clips and tabs) are not deformed.
5- Check the sealing of the connector.
Do the visual inspections highlight any damage?
NO YES
If there is a repair procedure (see Technical
Note 6015A, Electrical wiring repair, Wiring:
Precautions for repair), repair the connector,
otherwise replace the wiring.
After repair, restart the test from the beginning.

Checking the turbocharging pressure regulator for a turbocharger with variable geometry
Note:
The rod of the pressure regulator on a turbocharger with variable geometry is perpendicular to the turbocharger
shaft.
Turbochargers with variable geometry are controlled by a solenoid valve.
According to the vehicle type, maximum visual access will either be from above or from below.
Note:
If necessary, according to the vehicle type and the accessibility of the pressure regulator, connect the vacuum
pump to the end of the pressure regulator pipe at the solenoid valve outlet.
Using a manual vacuum pump, apply a vacuum on the turbocharging pressure regulator of approximately
650 mbar.
1- Check that the fitting is completely sealed.
2- Check that the control rod is resting against its stop.
3- Lock the vacuum device and check that the pressure variation is not greater than 100 mbar in 10 seconds.
4- Release the pressure and check that the control rod returns to its initial position without jerking.
Repeat the entire sequence three times.
Is the pressure regulator sealing and rod movement correct?
YES NO
The turbocharger is correct.
End of procedure.Replace the turbocharger (see MR 364 (Mégane II)
or 370 (Scénic II), Mechanical, 12B,
Turbocharging, Turbocharger: Removal -
Refitting and Technical Note 3938A, Broken

Checking the turbocharging pressure regulator for a turbocharger with fixed geometry
Note:
The pressure regulator rod for a turbocharger with fixed geometry is line with the turbocharger shaft.
Turbochargers with fixed, regulated geometry are controlled by a solenoid valve.
According to the vehicle type, maximum visual access will either be from above or from below.
Note:
If necessary, according to the vehicle type and the accessibility of the pressure regulator, connect the vacuum
pump to the end of the pressure regulator pipe at the solenoid valve outlet.
Using a manual vacuum pump, apply a vacuum on the turbocharging pressure regulator of approximately
650 mbar.
1- Check that the fitting is correctly sealed.
2- Check that the control rod moved several millimetres.
3- Lock the vacuum device and check that the pressure variation is not greater than 100 mbar over 10 seconds.
4- Release the pressure and check that the control rod returns to its initial position without jerking.
Repeat the entire sequence three times.
Is the pressure regulator sealing and rod movement correct?
YES NO
The turbocharger is correct.
End of procedure.Replace the turbocharger (see MR 364 (Mégane II)
