Check the resistance of the EGR valve:
–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 3VP and 3VQ of component 1460. The resistance should be
between 0.5 ΩΩ Ω Ω
< R < 50 Ω (while running command AC002 EGR solenoid valve).
If the value is not correct, replace the EGR valve, component code 1460 (see MR 364 (Mégane II), MR 370

Emission control, Exhaust gas recirculation solenoid valve: Removal - Refitting).
After replacing the EGR valve, 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 Technical Note 3916A, Cleaning the EGR solenoid
valve).
–Refit the EGR 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.
