If fault DF062 is present: there is engine noise and jerking, the engine runs on three
cylinders, the engine speed is held at 1000 rpm, the engine performance is reduced to
75%, and the level 1 warning light illuminates.
Conditions for applying fault finding procedures to stored faults:
The fault is present with the engine idling.
Priorities when dealing with a number of faults:
–DF029 Cylinder 4 injector control circuit (CC or CO),
–DF053 Rail pressure regulation function.
Check the presence and conformity of the fuel. Run TEST 13: Diesel fuel conformity check.
Run TEST 3 Injector check.

Check the engine compression.
Repair if necessary.
Check the valve clearance and adjust if necessary.
Check the inlet ducts, as well as the EGR valve, and clean them if necessary (see Technical Note 3916 Cleaning
the EGR solenoid valve).
If the fault is still present, replace the injector, component code 196 (see MR 364 (Mégane II), MR 370 (Scénic II),

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
(Scénic II), MR 385 (Modus), MR 392 (Clio III), MR 411 (New Twingo), MR 417 (Kangoo 2), Mechanical, 14A,
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.
