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),

Check the presence and conformity of the fuel. Run TEST 13: Diesel fuel conformity check.
Run TEST 3 Injector check.
Run TEST 7 High pressure circuit sealing 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),
