Check that the turbocharger and the control circuit are working:
–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 stops, the control rod should return to the rest position).
If the control rod does not move correctly, carry out the following checks:
1Check the control vacuum pressure:
–disconnect the solenoid valve inlet hose and connect it to a pressure gauge,
–start the engine and stabilise it at idle speed,
–If the vacuum does not reach 800 mbar ± 100: check the vacuum pressure circuit from the vacuum pump,
–stop the engine, reconnect the inlet hose and proceed to step 2.
2Solenoid valve control check:
–Disconnect the solenoid valve outlet hose,
–start the engine and stabilise it at idle speed,
–place your hand on the solenoid valve and block the outlet connection with your thumb,
–if there is no detectable vibration of the solenoid valve, check that the computer output is operating correctly (see
DF054 Turbocharging solenoid valve control circuit 1.DEF).
3Solenoid valve operation check:
–Attach the pressure gauge to the solenoid valve outlet union,
–start the engine and stabilise it at idle speed,
–if the vacuum pressure does not reach 800 mbar ± 100, replace the solenoid valve.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

NOTESPriority when dealing with a number of faults:
Deal with fault DF004 Turbocharger pressure sensor
circuit first if it is present or stored.
Check the turbocharging pressure sensor connections,
Check the connections of the turbocharging solenoid valve,
Check the injection computer connections.
Repair if necessary.
Check the conformity of the turbocharging pressure signal (refer to the interpretation of parameter PR041
Turbocharging pressure).
Make sure the turbocharging pressure relief solenoid valve is not jammed open:
–With the engine switched off, disconnect the inlet and outlet hoses from the solenoid valve.
–connect a vacuum pump to the inlet union and apply a vacuum pressure.
–if the vacuum pressure is not maintained: replace the solenoid valve.
Check that the turbocharger control rod has not seized:
–with the engine stopped, make sure the turbocharger control rod is in the rest position.
–apply a vacuum pressure of 800 mbar ± 100, to the hose connected to the turbocharger control diaphragm,
–if the diaphragm is affected by the vacuum, check the movement and setting of the turbocharger control rod (see
MR 364 (MEGANE II) and 370 (SCENIC II), Mechanical, 12B, Turbocharging).
If the control rod is seized, replace the turbocharger.
If the fault is still present, apply test 9 Air line at the turbocharger, then test 5 Turbocharger control solenoid
valve check and test 6 Turbocharger.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after a road test.
Priorities when dealing with a number of faults:
–DF118 EGR solenoid valve servo-control,
–DF209 EGR valve position sensor circuit,
–DF272 EGR valve control circuit,
if they are present or stored.
Special note:
If the fault is present:
–The EGR and turbocharging functions are inhibited.
–The level 1 warning light is lit.
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
IMPORTANT
If the EGR valve needs to be replaced to resolve the fault, use command SC036
Reinitialise programming and select EGR valve to reinitialise the EGR valve offsets
(see Replacement of components).
Check the EGR valve connections.
Check the injection computer connections.
Repair if necessary.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
