Check whether there are other cylinders with a combustion misfire fault detected by the
tool before starting the following fault finding procedure.
Conditions for applying the fault finding procedure to stored faults:
The fault is considered present under the following conditions:
– there must be no further electrical faults,
– programming must be carried out.
– warm engine (coolant temperature 75°C minimum),
– engine running at idling speed with all electrical consumers on for approximately
15 minutes.
Special note:
–OBD warning light illuminated.
1.DEF
NOTESSpecial note:
– As soon as the fault is detected, the injection is cut off on
the faulty cylinder(s) to limit the temperature increase in
the catalytic converter,
– if a fault is present, the OBD warning light flashes.
2.DEFSpecial note:
–the OBD warning light remains continuously lit.
AFTER REPAIRDeal with any faults declared by the diagnostic tool.

The fault is probably due to a component that can only affect this cylinder:
– check the cylinder 3 pencil coil,
– check the condition and conformity of the spark plugs,
– check the cylinder 3 injector.
If everything is in order, check the same components on cylinder 2 (to correct a possible
cylinder identification error).
The fault is probably due to a component that affects a pair of cylinders:
– check the ignition coil circuit concerned (apply the interpretation of fault DF362
Ignition coil 2-3 control),
– check the condition and conformity of the spark plugs.
The fault is probably due to a component affecting all the cylinders:
– check that the correct fuel is being used,
– check the condition and conformity of the spark plugs.
If the fault is still present, carry out the following checks:
– check the flywheel sensor,
– check the condition and cleanliness of the flywheel,
– check the mounting of the flywheel sensor,
– check the flywheel/sensor air gap,
– check the cylinder compressions,
– check the complete fuel system (see MR 364 or 370 Mechanics, 13A, Fuel supply, Petrol supply system),
– check the complete ignition system (see MR 364 or 370 Mechanics, 17A, Ignition, Spark plugs),
– check the hydraulic tappets if there is camshaft noise (see MR 364 or 370 Mechanics, 11A, Top and front of
engine).
If the fault is still present, deal with the other faults then proceed with the conformity check.
AFTER REPAIRDeal with any faults declared by the diagnostic tool.
