WARNING
This fault only appears in Vdiag 48.
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– a road test,
– an actuator command AC002 EGR solenoid valve.
Special notes:
The EGR and turbocharging functions are inhibited.
The level 1 warning light comes on.
Use bornier Ele. 1681 for all operations on the injection computer connectors.
Check the EGR valve connections.
Check the injection computer connections.
Repair if necessary.
Clear any stored faults.
Run command RZ002 EGR Adaptives to reinitialise the valve operating values.
Switch off the ignition and wait for the engine immobiliser warning light to start flashing.
Switch the ignition on again and check the system faults.
If the fault is still present:
– remove the EGR valve, and then reconnect it,
– check that the movement of the valve is not being blocked by a particle,
– check that the valve is not jammed or stuck in one position,
– run command AC002 EGR solenoid valve,
– check the movement of the solenoid valve,
– check that the solenoid valve is completely closed,
– if there is no movement, or if the valve is seized and cannot be repaired, replace the EGR solenoid valve.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present with the engine running and a heating and air
conditioning request
Priorities when dealing with a number of faults:
Firstly, deal with the following faults:
– DF049 Refrigerant sensor circuit if it is present or stored.
When the fault is present or stored, the heating and air conditioning system is inhibited.
Check fuse F22 (10A) of the UPC and the condition of the air conditioning compressor connector.
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the air conditioning compressor wiring.
If the wiring is faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Manually check if the compressor is jammed (turn the clutch plate manually to check that there is no point of
resistance). In the event of sticking, replace the air conditioning compressor (see MR 364 (Mégane II) or 370
(Scénic II), Mechanical, Heating and air conditioning system, 62A, Air conditioning, Compressor: Removal
- Refitting).
Top up with freon, check for any leaks and repair if necessary (see MR 364 (Mégane II) or 370 (Scénic II),
Mechanical, Heating and air conditioning system, 62A, Air conditioning, Refrigerant circuit: check,
Refrigerant circuit: Draining - Filling).
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.
