Check the condition of the EGR valve (see Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2,
Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 1460 or 169).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 120).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Measure the resistance between connections 3EL and 3JM of component 1460 or 169.
If the resistance of the EGR valve is not between 1 kΩ < X < 7,5 kΩ, replace the EGR valve.
Measure the resistance between connections 3EL and 3GC of component 1460 or 169.
If the resistance of the EGR valve is not between 3.9 kΩ < X < 12.6 kΩ, replace the EGR valve.
After replacement, run command SC036 Reinitialise programming and select EGR valve to reinitialise the EGR
valve offsets.
Check the continuity and absence of interference resistance of the following connections:
•3GC between components 120 and 1460 or 169,
•3EL between components 120 and 1460 or 169,
•3JM between components 120 and 1460 or 169.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring,
otherwise replace the wiring.
Remove and clean the EGR valve, then refit the EGR valve and start the engine (see MR364 (Mégane II ph2),
MR370 (Scénic II ph2), MR 395 (Laguna II ph2), 402 (Vel Satis ph2), 405 (Espace IV ph2), Mechanical, 14A,
Emission control, Exhaust gas recirculation solenoid valve: Removal - Refitting).
If the fault is still present, replace the EGR valve then run command SC036 Reinitialise programming and select
EGR valve to reinitialise the EGR valve offsets.

STOREDREGENERATION TEMPERATURE LIMIT EXCEEDED
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present during an After-Sales regeneration, if the temperature
threshold is exceeded.
Special notes:
If the fault is present:
– regeneration in progress is stopped.
IMPORTANT: The fault appears if the temperature threshold is exceeded during
the After-Sales regeneration phase.
• Carry out particle filter replacement
• run command SC036 Reinitialise programming (see Interpretation of commands) and select After particle
filter replacement.
•switch off the ignition and wait for the diagnostic tool message (maximum wait 8 minutes): Loss of
dialogue with the computer: EDC16 CP33, check the tool connection and the computer supply voltage,
• then switch on the ignition again,
•clear the present or stored faults from the computer memory (operation to be carried out within 3 minutes
of switching on the ignition).
If the fault is still present, contact the Techline.

1.DEF: Configuration / Initialisation
NOTESSpecial notes:
If the fault is present:
– engine torque limited,
– an engine speed below 1500 rpm.
The level 1 warning light is illuminated.
Conditions under which the fault appears:
This fault only appears when the computer is reprogrammed after a change of Vdiag.
If the fault is present, display status ET781 Heater plugs in the sub-function Ignition/Preheating.
If status ET781 is STATUS 3, this means that the heater plugs are not configured in the injection computer.
To find out which type of heater plugs are fitted to the engine, look at the colour of the rings on the plugs.
– Slow plugs have a black ring.
– Fast plugs have a white ring.
To configure the type of plugs, run command SC036 Reinitialise programming and select HEATER PLUGS (see
Interpretation of commands).
If the fault is stored, clear the fault.
End of fault finding.
If the fault is still present or if status ET781 is not STATUS 3 or is inconsistent with the type of plug fitted, contact
the Techline.
