NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– engine speed is between idling speed and 1050 rpm PR055 Engine speed,
– a coolant temperature ≥ 50°C PR064 Coolant temperature.
Priorities when dealing with a number of faults:
DF249 Injector control, present or stored,
DF026 Injector 1 control circuit, present or stored,
DF027 Injector 2 control circuit, present or stored,
DF028 Injector 3 control circuit, present or stored,
DF029 Injector 4 control circuit, present or stored.
IMPORTANT
When removing or refitting an injector, observe the cleanliness and safety instructions
(see MR 364 (Mégane) or 370 (Scénic), Mechanical, 13B, Diesel injection, Diesel
injector: Removal - Refitting).
IMPORTANT
Possible absence of combustion on one cylinder even though the injector is properly
fed.
Do not disconnect the injectors when the engine is running.
