Checking the turbocharging pressure regulator to determine if it is a variable geometry turbocharger
Note:
The pressure regulator rod of a variable geometry turbocharger is orthogonal to the turbocharger shaft.
Variable geometry turbochargers are controlled by a solenoid valve.
Depending on the vehicle type, the best visual access will be either 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 leaktight.
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 comes back to its initial position without jerking.
Repeat the complete sequence 3 times.
Is the pressure regulator leaktight and is the rod movement correct?
The turbocharger is correct.
End of procedure.Replace the turbocharger (see MR 364 (Mégane II), 370

Checking the turbocharging pressure regulator to determine if it is a fixed geometry turbocharger
Note:
The pressure regulator rod of a fixed geometry turbocharger is aligned with the turbocharger shaft.
Fixed geometry turbochargers are controlled by a solenoid valve.
Depending on the vehicle type, the best visual access will be either 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 leaktight.
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 in 10 seconds.
4. Release the pressure and check that the control rod comes back to its initial position without jerking.
Repeat the complete sequence 3 times.
Is the pressure regulator leaktight and is the rod movement correct?
The turbocharger is correct.
End of procedure.Replace the turbocharger (see MR 364 (Mégane II), 370
