NOTESPerform this fault finding procedure:
– following interpretation of an unresolved fault or
– after processing the interpretation of PR041 Turbocharging pressure or
– after a customer complaint (loss of power, smoke etc.).
Ignition on and engine stopped.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
1. The following procedure is for checking that the turbocharger and its control circuit are working
properly.
Check the sealing of the high pressure air circuit, run test 3 Low pressure circuit check
Pipe not joined or pierced, pressure sensor disconnected or poorly fitted (seal present), exchanger pierced.
To test the exchanger: stabilise the engine speed between 3500 and 4000 rpm with the vehicle stopped and check
that there are no leaks.
Measure the resistance of the turbocharging pressure solenoid valve between the following connections:
– Connection code 3MG,
– Connection code 3FB,
of component 1475.
Replace the solenoid valve if its resistance is not: 20 Ω ± 2 at +23°C.
Check the continuity, insulation, and the absence of interference resistance on the following connections:
– Connection code 3MG between components 1475 and 120.
– Connection code 3FB between components 1475 and 983.
Run command AC004, if a faint whistling noise is heard along with a clicking from the solenoid valve, go to step
2, otherwise check the operation of the computer output stage:
Vehicle under + after ignition feed, clear the faults displayed by the diagnostic tool.
With the voltmeter in the direct current position:
With the turbocharging solenoid valve connected, connect the voltmeter earth lead to connection 3MG of
component 1475 and the positive lead to connection3FB.
Run command AC004, the voltmeter should display four successive voltages of 2.4 V ± 0.2 V.
If the measurement is not correct, contact the Techline.

2. Turbocharger control circuit check:
– With the engine stopped, make sure that the control rod is in the resting position.
– Start the engine and make sure that the control rod actuates to the upper stop.
(when the engine is switched off, the control rod should return to the rest position)
If the control rod does not move correctly, carry out the following checks:
1) Control vacuum check:
– Disconnect the solenoid valve inlet hose and connect it to a pressure gauge.
– Start the engine and run it at a stable idle speed.
– If the vacuum does not reach 400 mbar ± 150: check the vacuum pressure circuit from the vacuum pump.
– Stop the engine, reconnect the intake hose and go to step no. 2.
2) Solenoid valve control check:
– Disconnect the solenoid valve outlet hose.
– Start the engine and run it at a stable idle speed.
– Place your hand on the solenoid valve and block the outlet union with your thumb.
– If there is no perceptible vibration of the solenoid valve, contact the Techline.
3) Solenoid valve operation check:
– Connect the pressure gauge to the solenoid valve outlet union.
– Start the engine and run it at a stable idle speed.
If the vacuum does not reach 400 mbar ± 150, replace the solenoid valve.

otherwise, check that the computer output stage is operating correctly:
Vehicle under + after ignition feed, clear the faults displayed by the diagnostic tool.
With the voltmeter in the direct current position:
With the pressure regulator connected, connect the voltmeter earth lead to connection 3HI of component 1105

Step 2
In the event of rail overpressure:
Check that there are no air bubbles in the diesel fuel low pressure circuit.
Check that the rail pressure sensor is operating correctly.
Consult the interpretation of parameter PR038 Rail pressure.
If these checks reveal no irregularities, replace the regulator.
in the event of rail underpressure:
Check that the rail pressure sensor is operating correctly.
Consult the interpretation of parameter PR038 Rail pressure.
Check the low pressure diesel circuit priming.
Check the conformity of the diesel filter connections.
Check the condition of the filter (clogging and water saturation).
Check that there are no air bubbles between the filter and the high pressure pump.
Check the sealing of the low and high pressure diesel fuel systems: use ALP6 Fuel circuit leaks (visual
inspections, touch tests, odours, etc.) on:
pump body, pressure release valve, pipes, rail and injectors unions, injector wells, etc.
Check the conformity of the seal fitting on the pressure regulator.
Check the operation of the injectors, run Test 10 Poor injector operation.
Carry out the necessary repairs.
If the engine starts:
Clear any faults.
Check the pressure regulator by applying (see ALP7 Rough idle).
With the engine warm, leave it to idle for a few minutes (3 to 5 minutes):
– If it stalls and the fault reappears, replace the regulator.
– If it does not stall, stabilise the engine speed at 2000 rpm(1 minute) then accelerate at full load until it cuts out.
If the engine stalls, contact the Techline
If the engine does not startor there is no timing:
first, replace the regulator and if the fault is still present, contact the Techline.
