Check the resistance of the EGR valve, component code 169:
– with the engine stopped, the EGR valve will be closed (unless there is a fault),
– wait for the ambient temperature around the valve to stabilise (approximately 20°C),
– measure the resistance between connections 3FB2 and 3GB. The resistance must be between
7.5Ω – measure the resistance between connections 3GC and 3JM. The resistance must be between
2.4 kΩ – measure the resistance between connections 3JM and 3EL. The resistance must be between
800Ω If the value is not correct, replace the EGR valve, component code 169 (see MR 364 (Mégane II), MR 370 (Scénic
II), Mechanical, 14A, Emission control, Exhaust gas recirculation solenoid valve: Removal - Refitting). If the
EGR valve was replaced, use command RZ002 EGR adaptives to reinitialise the EGR valve offsets.
Also, if a 3.DEF, 4.DEF, or 5.DEF fault is present:
Remove the EGR valve. Check that there are no foreign bodies (scale, etc.) that could jam the valve.
Remove the foreign matter and clean the EGR valve (see MR Technical Note 3916, Cleaning the EGR solenoid
valve).
Use command RZ002 EGR adaptives to reinitialise the EGR valve offsets.
Clear the faults from the computer memory. Carry out a road test followed by another check with the diagnostic
tool.
If the fault is still present, contact the Techline.

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present with the engine running and with a climate control request.
Priorities when dealing with a number of 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. There is no longer any air
conditioning.
Check fuse F22 (10 A) of the UPC, component code 1337.
Check the connector of the air conditioning compressor, component code 171.
