Program the injector codes using command SC002 Enter injector codes.
Carry out the procedure described in the Interpretation of commands section.
If the fault is still present after switching off the ignition, waiting for 1 minute and then re-establish dialogue,
Follow the interpretation of command SC002 Entering injector codes.
If the fault is still present, contact the Techline.

WARNING
A computer without the IMA option can be replaced by a computer with this option. The codes are not
saved during command SC003 Save computer data.
In this case, status ET104 Use of Injector Codes becomes YES, fault DF276 Injector Code Programming
will be present, and the engine will operate in defect mode.
Program the injector codes using command SC002 Enter injector codes.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present when the ignition is switched on or with the engine
running.
Special notes:
If the fault is present, the level 1 warning light comes on.
IMPORTANT
The fault can appear after the alternator has been saturated for too long.
For stored faults, clear the fault, switch off the ignition and wait for 1 minute before
carrying out a road test to confirm the fault before any operation.
Run a multiplex network test (see 88B, Multiplexing).
If the fault is still present, check the insulation and continuity on the following connection:
Injection computer, connector C, track A3Alternator, Track 2, black connector
Repair if necessary.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

Check the operation of the EGR valve:
–exit fault finding mode in CLIP,
–switch off the vehicle ignition,
–disconnect the EGR valve connector,
–remove the EGR valve.
–Check that there are no particles blocking the movement of the piston.
–Clean the EGR valve, (see Technical Note 3916A Cleaning the EGR valve).
–Refit the EGR valve, run command SC036 Reinitialise programming and select EGR valve to reinitialise the
EGR valve offsets (see Replacement of components).
If the valve is jammed or irrevocably seized, replace the EGR valve. Run command SC036 Reinitialise
programming and select EGR valve to reinitialise the EGR valve offsets (see Replacement of components).

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:
–there is heavy smoke coming from the exhaust,
–the OBD warning light will come on after three consecutive driving cycles (starting
+ 5 seconds + switching off the ignition and waiting 1 minute).
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.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault becomes present:
–ignition is on (CC.0),
–following a road test, engine warm (CO.1).
Special notes:
If the fault is present:
–the EGR function is inhibited,
–particle filter regeneration is inhibited,
–the vehicle performance is reduced,
–the level 1 warning light is illuminated.

IMPORTANT
The turbine upstream temperature sensor only measures temperatures above
200˚C.
Check the condition of the turbine upstream temperature sensor connector (see Wiring Diagram Technical Note,
Mégane II, Scénic II, component code 1589).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Mégane II, Scénic II, component code 120).
If one of the connectors is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring
repair, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
